HOW TO OBTAIN TECHNICAL MANUALS
When a new system is introduced to the Army inventory, it is the responsibility of the receiving units to
notify and inform the Unit Publications Clerk that a Technical Manual is available for the new system.
Throughout the life cycle of the new system, the Distribution Center DOL-W will also provide updates and
changes to the Technical Manual.
To receive new Technical Manuals or change packages to existing Technical Manuals (TM) for fielded
equipment, provide the Unit Publications Clerk the full Technical Manual number, title, date of publication,
and number of copies required. The Unit Publications Clerk will justify the request through the Unit
Publications Officer. When the request is approved, the Unit Publications Clerk will use DA Form 12-R to
order the series of Technical Manuals from the Army Publishing Directorate (APD).
Instructions for Unit Publications Clerk

Manual Organization and Page Numbering System. The manual is divided into five major chapters that
ix
TM 10-1670-276-23&P
detail the topics mentioned above. Within each chapter are work packages covering a wide range of
topics. Each work package is numbered sequentially starting at page 1. The work package has its own
page-numbering scheme and is independent of the page numbering used by other work packages. Each
page of a work package has a page number of the form, XXXX YY, where XXXX is the work package
number (e.g., 0010 is work package 10), and YY is the revision number for that work package. A page
number such as 0010 00-1/2 Blank means that page 1 contains information but page 2 of that work
package has been intentionally left blank.
Finding Information. The table of contents permits the reader to find information in the manual quickly.
The reader should start here first when looking for a specific topic. The table of contents lists the topics
contained within each chapter and the work package sequence number where it can be found.
Example: If the reader were looking for instructions on Splicing Radial Tape, which is a unit maintenance
topic, the table of contents indicates that the unit maintenance information can be found in Chapter 3.
Scanning down the listings for Chapter 3, Radial Tape information can be found in WP 0018 (Work
Package 18).
An Alphabetical Index can be found at the back of the manual; specific topics are listed with the
corresponding work package number.

CORROSION PREVENTION AND CONTROL (CPC)
Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any
corrosion problems with this item be reported so that the problem can be corrected and improvements can
be made to prevent the problem in future items.
While corrosion is typically associated with rusting of metals, it can also include deterioration of other
materials, such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of these
materials may be a corrosion problem.
If a corrosion problem is identified, it can be reported using Standard Form SF 368, Product Quality
Deficiency Report. Use of keywords such as "corrosion,” "rust," "deterioration," or "cracking" will ensure
that the information is identified as a CPC problem.
The form should be submitted to the address specified in DA PAM 750-8, Functional Users Manual for the
Army Maintenance Management System (TAMMS).
PREPARATION FOR STORAGE AND SHIPMENT
For storage and shipment, refer to TM 10-1670-201-23/T.O. 13C-1-41/NAVAIR 13-1-17, and WP 0037 of
this manual.
DESTRUCTION OF ARMY MATERIEL TO PREVENT ENEMY USE
GENERAL INFORMATION:
Objective
Methods of destruction used to inflict damage on air delivery equipment should make it impossible to
restore equipment to a usable-condition in a combat zone, by either repair or cannibalization.
Authority
Destruction of air delivery equipment that is in imminent danger of capture by an enemy is a command
decision that must be made by a battalion or higher commander, or the equivalent.
Implementation Plan
All units that possess air delivery equipment should have a plan for the implementation of destruction
procedures.
0001-2
TM 10-1670-276-23&P
0001
Training
All personnel, who use or perform such functions as rigging, packing, maintenance, or storage of air
delivery equipment, should receive thorough training on air delivery equipment destruction procedures and
methods. The destruction methods demonstrated during training should be simulated. Upon completion
of training, all applicable personnel should be thoroughly familiar with air delivery equipment destruction
methods and be capable of performing destruction without immediate reference to any publication.
SPECIFIC METHODS
Specific methods of destroying Army materiel to prevent enemy use shall be by mechanical means, fire, or
by use of natural surroundings.
Destruction by Mechanical Means
Air delivery equipment metal assemblies, parts, and packing aids shall be destroyed using hammers, bolt
cutters, files, hacksaws, drills, screwdrivers, crowbars, or other similar devices used to smash, break,
bend, or cut.
WARNING
Exercise extreme care when using petroleum products to destroy
equipment by fire, as these materials are highly flammable.
Improper handling may cause injury to personnel.
Destruction by Fire
Items that can be destroyed by fire shall be burned. The destruction of equipment by use of fire is an
effective method of destroying low-melting-point metal items (e.g., side rails, threaded portions of nuts and
bolts, and platforms). However, mechanical destruction should be completed first, whenever possible,
before initiating destruction by fire. When items to be destroyed are made of metal, textile materials (or
some comparable low combustible material) should be packed under and around the items, then soaked
with a flammable petroleum product and ignited. Proper concentration of equipment, that is suitable for
burning, will provide a hotter and more destructive fire.
Destruction by Use of Natural Surroundings
Small vital parts of assemblies, that are easily accessible, may be disposed of as follows: Disposal or
denial of equipment to an enemy may be accomplished through use of natural surroundings. Accessible
vital parts of assemblies may be removed and scattered through dense foliage, buried in dirt or sand, or
thrown into a lake, stream, or other body of water. Total submersion of equipment in a body of water will
provide water damage as well as concealment. Salt water will inflict extensive damage to air delivery
equipment.

OVERVIEW
This chapter contains information necessary to maintain the 26-Foot Diameter, High-Velocity Cargo
Parachute, on the Field maintenance levels, in accordance with the Maintenance Allocation Chart (MAC)
for the equipment. It includes the following:
1. Procedures for processing a new or used parachute assembly upon receipt.
2. Assembly of components prior to packing.
3. Preventive maintenance procedures to ensure continued serviceability of all components.
4. As required, inspections and maintenance procedures performed prior to packing, such as shakeout
and airing, and cleaning and drying, and acidity and salt-water contamination tests.
5. Detailed packing procedure.
6. Repair methods and repair, or replacement, procedures for all components of the parachute
assembly.
INITIAL RECEIPT
The following describes the procedures for processing parachutes upon initial receipt.
General Procedures for Air Delivery Equipment
When air delivery equipment is initially procured from a supply source and issued to a using unit, the
item(s) will be unpacked from the shipping container(s) and inspected by a qualified parachute rigger
(MOS 92R). The inspection will be a technical/ rigger-type inspection and will be conducted as outlined in
the Preventive Maintenance Checks and Services (PMCS) procedures. Upon completion of the
inspection, the item(s) will be tagged as prescribed in DA PAM 738-751. Serviceable equipment may then
be entered either into storage or into use in airdrop operations, as applicable. An unserviceable item will
be held and reported in accordance with DA PAM 750-8/MCO 4855.10B.
0003-1
TM 10-1670-276-23&P
0003
Inspection Personnel
Personnel other than parachute rigger personnel may assist in the unpacking process of initially received
parachutes, as directed by the local Airdrop Systems Technician (921A) or Senior Airdrop NCO (92R4P)
and above, under guidance from an Airdrop Systems Technician assigned to the command at the
Battalion level or higher, when no Airdrop Technician is assigned at the Company/Detachment/Team
level. However, the entire unpacking effort must be conducted under the direct supervision of a qualified
rigger (92R).
Configuration Condition
Acceptance of new equipment from the manufacturer is based upon inspections made of sample lots that
have been randomly selected in accordance with military standards. It is incumbent upon the using
activity personnel to bear this in mind whenever equipment is first placed in service. Changes will
sometimes evolve from the original equipment design, and sometimes contractors are authorized
deviations in material and construction techniques. Air delivery equipment that has been in the field
cannot be expected to meet exacting manufacturing specifications; however, the equipment should closely
reflect desired design characteristics. Since repairs, modifications, and/or changes can alter or detract
from the configuration originally desired, such equipment shall be airworthy, safe, of the desired
configuration, and adequate for intended use.
Marking Parachutes
Prior to being placed into service, personnel parachutes that have had no previous use will be marked to
reflect the date of entry into service. The marking will be made on the canopy information data block by
stenciling the lettering in minimum ½-inch characters, using the marking and restenciling repair
procedures detailed in WP 0014. Other applicable parachute components will be marked adjacent to
existing data. The stenciled data will appear on IN-SVC followed by the date, which will indicate the
month and calendar year, such as "Jan. 05". Ensure the added marking does not infringe upon, or
obliterate, any original data on the information data block.
Parachute Log Record
The Army Parachute Log Record, DA Form 3912, AFTO 391 is a history-type maintenance document that
accompanies the parachute canopy and pack tray assemblies through the period of service of the
individual assembly. The log record provides a means of recording maintenance actions performed on a
parachute canopy assembly. Normally, a log record is initiated and attached to a riser assembly (main
parachute) or pack tray (reserve parachute) upon receipt by a using unit. If the item is subjected to
alteration or modification by a maintenance activity during the interim period, from date of manufacture to
receipt by a using unit, the log record will be prepared by the activity performing the maintenance function.
Once initiated, a log record will be attached to and contained in an affixed parachute log record/inspection
data pocket, until such time as the parachute canopy assembly is destroyed or rendered unfit for further
use or repair.
Additionally, should an item that requires a log record be transferred from one unit to another, the log
record for the parachute assembly will accompany the item in the transfer action. A prepared log record
will not be removed or separated from a parachute, especially a packed parachute, except as directed by
the local air delivery equipment maintenance activity officer or aerial delivery NCOIC.
A log record that is illegible, lost, damaged, soiled, or precludes further entries due to lack of space will be
replaced upon the next repack or inspection, as applicable, with a serviceable item from stock.

SERVICE AND FIELD MAINTENANCE
26-FOOT DIAMETER, HIGH-VELOCITY CARGO PARACHUTE ASSEMBLY
PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS), INTRODUCTION
GENERAL
The following paragraphs describe PMCS procedures for the Service maintenance support level. The purpose
of PMCS is to ensure the 26-Foot Diameter, High-Velocity Cargo Parachute is in proper operating condition
and ready for its primary use.
SCOPE
The scope of this work package is to provide guidance on the PMCS procedure, what to do once a fault is
identified, and how to record faults.
MAINTENANCE FUNCTIONS/PROCEDURES
Each of the mentioned work packages above identifies a maintenance function specified in the MAC.
PARACHUTE REPACK INTERVAL
The 26-Foot Diameter, High-Velocity Cargo Parachute will be repacked at a scheduled interval to ensure
airworthiness. When necessitated by climate/storage/use condition, the local Airdrop Systems Technician
(921A) or Senior Airdrop NCO (92R4P) and above, under guidance from an Airdrop Systems Technician
assigned to the command at the Battalion level or higher, when no Airdrop Technician is assigned at the
Company/Detachment/Team level, may require more frequent repack intervals. In this regard, a major
concern would be rapid fluctuations of temperature (fluctuations around 32 degrees Fahrenheit, freezing
point), sustained high or low temperature, or high humidity and a heavily-polluted atmosphere. The 26-Foot
Diameter, High-Velocity Cargo Parachute will be repacked every 365 days. However, the repack cycle of the
26-Foot Diameter, High-Velocity Cargo Parachutes stored in depots and facilities that maintain contingency
stocks of 26-Foot-Diameter Parachutes, which are specifically identified as “PACKED FOR CONTINGENCY”
and stored separately from normal parachute stock, will be repacked at a 144-month interval. This is only to
occur providing the storage conditions are in accordance with this TM.
DROP-TESTING CRITERIA
Drop-testing the 26-Foot Diameter, High-Velocity Cargo Parachute consists of physically airdropping an item
from an aircraft in flight. The drop-test is used as a means of proving the serviceability of an item or checking
parachute rigger proficiency and will only be performed under the supervision of qualified parachute rigger
personnel who satisfy the supervisory requirements outlined in AR 750-32. Drop testing will usually be
conducted by an activity responsible for the inspection and maintenance of airdrop equipment, which includes
either parachute packing or airdrop load rigging. The criteria required to accomplish a drop-test is as follows:
1. During the drop-test of any type parachute, the deployment of the parachute will be thoroughly monitored
and observed to detect any indication of malfunction or defect. Any defect or malfunction detected in a
drop-test will be annotated in the log record book using procedures outlined in WP 0003, SERVICE
UPON RECEIPT.
2. Any type of airdrop equipment that indicates evidence of malfunction/defect, during or after a drop-test,
will be disposed of as prescribed in WP 0009, INSPECTION.
3. Airdrop equipment that does not reflect evidence of malfunction or defect upon completion of a test-drop
will be administered a technical/rigger-type inspection as outlined in WP 0009, INSPECTION. If items are
deemed serviceable, the item(s) may then remain in use.

GENERAL
The following paragraphs describe PMCS procedures for the service maintenance level. Table 1 has been
provided to ensure the 26-Foot Diameter, High-Velocity Cargo Parachute is in proper operating condition and
ready for its primary mission.
Warnings and Cautions
Warnings and cautions appear before applicable procedures. You must observe these warnings and cautions
to prevent serious injury to yourself and others and to prevent damage to equipment.
Frequency of Performing PMCS
PMCS will be performed before equipment is packed for use, during modification and repair, after use, or at
any time deemed necessary by the air delivery equipment maintenance supervisor.
PMCS Table Column Entries
Enter data in the columns as follows:
● Item number. Item number required for the TM number column on DA Form 2404 (Equipment
Inspection and Maintenance Worksheet) when recording the results of PMCS.
● Interval. Required PMCS level.
● Item to be inspected. Common name of the item to be inspected.
● Procedures. Brief description of the procedure by which the checks are to be performed.
Recording Defects
All defects discovered during the inspection will be recorded using the applicable specifics in DA PAM 750-8,
DA PAM 738-751, and TB 43-0002-43.
Conservation of Resources
To conserve time and labor, and to avoid evacuation to an intermediate maintenance activity, unit/detachment
commanders may designate, in writing, rigger personnel to accomplish classification inspection of overage air
delivery equipment. The 26-Foot Diameter High-Velocity Cargo Parachute has no age or service life.
Inspection Function Requirement
Normally, airdrop equipment maintenance personnel at a packing, rigging, or repair activity will perform a
technical/rigger-type inspection. The inspection of initial receipt items will be performed as a separate
function from packing or rigging activity; the item to be inspected will be placed in proper layout on a packing
surface or suitably-sized floor area.
Should any defect or damage be discovered at any point during the inspection, the inspection will be
terminated, and the applicable item will be processed and forwarded to the repair activity. The repair activity,
in turn, will conduct a technical/rigger-type inspection that will be performed by only those parachute rigger
personnel cited in AR 750-32.
Any defect discovered during a service level repair activity inspection, that exceeds the capability of that
activity, will require the affected item to be evacuated to a field maintenance function for further determination
of economic repair and repair accomplishment, if applicable.

SHAKEOUT
A two-person team, either indoors within a shakeout room or outdoors at a shakeout tower, will
accomplish the shakeout. Each parachute will be suspended by the canopy bridle loop and all debris
removed by shaking the canopy thoroughly or by brushing with a dry, soft-bristled brush, as detailed
below:
1. With assistance from the No. 2 person, the No. 1 person will connect the snap on a pulley rope to the
canopy bridle loop.
Figure 1. Attaching Rope to Canopy.
2. Through use of the pulley rope, the No. 2 person will raise the canopy to a suitable height; this will
enable the No. 1 person to perform shakeout on each of the canopy gores. Until the gore shaking
process is completed, the No. 2 person will maintain a steady pull on the pulley rope to hold the
suspended canopy at the working height needed by the No. 1 person.
0007-1
TM 10-1670-276-23&P
0007
3. The No. 1 person will grasp any two-consecutive suspension lines, one in each hand, and vigorously
shake the first gore. When the gore is free of debris, the No. 1 person passes the line from the right
hand to the left hand and grasps the next consecutive suspension line in the right hand. The No. 1
person will shake out each consecutive gore until all suspension lines are held in the left hand and all
gores are free of debris.
Figure 2. First Gore.
4. Once the gore shaking process is completed, the No. 2 person will slowly raise the suspended canopy
higher as the No. 1 person clears the suspension lines of debris and removes entanglements, when
possible.
Figure 3. Entanglement.
0007-2
TM 10-1670-276-23&P

5. After the suspension lines have been cleared, the No. 2 person may hold, or temporarily secure, the
pulley rope while the No. 1 person proceeds to clear debris from other parachute components such as
the risers, harness, and pack tray. When all components are free of debris, the No. 2 person will
slowly lower the canopy, while the No. 1 person S-folds the suspension lines into a suitably-sized
container. After the suspension lines have been completely folded, the No. 1 person will accordionfold the canopy length on top of the folded lines.
Figure 4. S-Fold Suspension Lines.
6. As the canopy folding is being completed, the No. 1 person disconnects the canopy vent from the
pulley rope snap. Secure the folded canopy assembly for further handling.
END OF TASK
AIRING
Where dampness and mildew are prevalent, air delivery equipment will be aired at frequent intervals
according to the severity of the prevailing conditions. Parachutes that have been previously packed or are
unpacked, and have been subjected to conditions of dampness or mildew, will be aired for a period of at
least 6 hours prior to being repacked. Air delivery items may be aired either indoors or outdoors, in dry
weather. However, fabric items will not be aired in direct sunlight. Airing may be accomplished by
suspending or elevating the applicable item(s) in a manner that would allow maximum exposure to air
circulation. Outside facilities used for the shakeout of parachutes may be used for the airing of air delivery
equipment, if weather conditions permit. If the shakeout facilities are inadequate for airing, the applicable
item(s) may be suspended or elevated at several points, or draped over suitable type objects that will not
cause damage.

NOTE
Cleaning of parachutes should be held to a minimum and should be
performed only when necessary, to prevent malfunction or
deterioration. When a parachute contains debris, or when it is soiled
by dirt, oil, grease, rust, corrosion, or other foreign substances, to
such an extent that cleaning is necessary, the cleaning should be
performed manually and should be limited to the soiled area only,
unless the parachute has been contaminated by water. The
methods of cleaning must be determined by the nature of the
substance to be removed. Do not use cleaning solvent to clean
items soiled by airsickness. Use a solution of hand dishwashing
compound to clean this type of soiling.
CLEANING FABRIC ITEMS WITH A SOLUTION OF HAND DISHWASHING COMPOUND
Use dishwashing compound to clean fabric items as follows:
1. Gently brush with a soft bristle brush.
2. Spot clean with a solution of dishwashing compound.
a. Dissolve one-half cup of dishwashing compound in one gallon of warm water.
b. Rub the soiled area with a clean cloth dampened with a solution of dishwashing compound.
c. Rinse the cleaned area by repeating the rubbing process, with a clean portion of the cloth
dampened with water.

TECHNICAL/RIGGER-TYPE INSPECTION PROCEDURES
Perform inspection as follows:
1. Overall inspection. An overall inspection will be made on the 26-Foot HV parachute to ascertain the
following:
a. Log record/parachute inspection data pocket and form. As applicable, inspect the assembly log
record parachute inspection data pocket to ensure the Army Parachute Log Record (DA Form
3912), NAVWPNCEN or NAVWPNS CL 13512/11(Parachute History Record) is enclosed and
properly attached. Further, remove the log record from the pocket and evaluate the recorded
entries. Inspect and evaluate as follows:
The Army Parachute Log Record, DA Form 3912, and AFTO 391 are history-type maintenance
documents that accompany the parachute canopy and pack tray assemblies through the period
of service of the individual assembly. The log record provides a means of recording
maintenance actions performed on a parachute canopy assembly. Normally, a log record is
initiated and attached to a right rear riser upon receipt by a using unit. However, if the item is
subjected to alteration or modification by a maintenance activity, during the interim period from
date of manufacture to receipt by a using unit, the log record will be prepared by the activity
performing the maintenance function. Once initiated, a log record will be attached to and
contained in an affixed parachute log record/inspection data pocket, until such time as the
parachute canopy assembly is destroyed or rendered unfit for further use or repair.
Additionally, should an item that requires a log record be transferred from one unit to another,
the log record for the parachute assembly will accompany the item in the transfer action. A
prepared log record will not be removed or separated from a parachute, especially a packed
parachute, except as directed by the local air delivery equipment maintenance activity officer.
A log record that is illegible, lost, damaged, soiled, or precludes further entries due to lack of
space, will be replaced upon the next repack or inspection, as applicable, with a serviceable
item from stock.
b. Assembly completeness. Ensure the applicable assembly is complete and that no components
(or parts) are missing.
c. Operation adequacy. Check the item components and parts to ensure proper assembly, which
includes attachment and alignment, and that the assembled product functions in the prescribed
manner. Further, ensure that no stitch formation (or sewn seam) has been omitted.
d. Markings and stenciling. Inspect each assembly and components for faded, illegible,
obliterated, or missing informational data and identification numbers.
e. Foreign material and stains. Inspect each assembly and related components for the presence
of dirt or similar type foreign material. Also check for evidence of mildew, moisture, oil, grease,
pitch, resin, or contamination by salt water.
2. Detailed inspection. In addition to the overall inspection performed in 1, above, a detailed inspection
will be performed on the materials that constitute the assembly or component construction, using the
0009-2
TM 10-1670-276-23&P
0009
following criteria, as applicable:
a. Metal. Inspect for rust, corrosion, dents, bends, breaks, burrs, rough spots, sharp edges, wear,
deterioration; damaged, loose or missing grommets, safety pins, connector snap, eye hook,
pack fastener; improper swaging or welding; loss of spring tension; and missing or loose
screws.
b. Cloth. Inspect for breaks, burns, cuts, frays, holes, rips, snags, tears; loose, missing, or broken
stitching or tacking; and weak spots, wear, or deterioration.
c. Fabric tape, webbing, and cordage. Inspect for breaks, burns, cuts, frays, holes, snags, tears,
incorrect weaving, and sharp edges formed from searing; loose, missing, or broken stitching,
tacking, whipping, and weaving; weak spots, wear, and deterioration.
d. Pressure-sensitive (adhesive) tape. Inspect for burns, holes, cuts, tears, weak spots, and
looseness and deterioration.
e. Rubber and elastic. Inspect for burns, cuts, holes, tears, weak spots, loss of elasticity and
deterioration.
END OF TASK
IN-STORAGE INSPECTION
An in-storage inspection is a physical check conducted on a random sample of air delivery equipment that
is located in storage. The purpose of the inspection is to ensure that the equipment is ready for issue, that
the item is properly identified and segregated from other types of equipment, that no damage or
deterioration of equipment has been incurred, and that all modifications or similar action requirements
have been completed. The inspection shall also concern the methods and procedures applied to the
storage of air delivery items, the adequacy of storage facilities, efforts of pest and rodent control, and
protection against unfavorable climatic conditions. Air delivery equipment that is in storage will be
inspected at least semiannually and at more frequent intervals if prescribed by the local parachute
maintenance advisor. The frequency of inspection may vary according to the type of storage facilities and
local climatic conditions. Only parachute rigger personnel designated by the local Airdrop Systems
Technician (921A) or Senior Airdrop NCO (92R4P) and above, under guidance from an Airdrop Systems
Technician assigned to the command at the Battalion level or higher, when no Airdrop Technician is
assigned at the Company/Detachment/Team level, will conduct in-storage inspections.
END OF TASK
EQUIPMENT DISPOSITION
Air delivery equipment may be rendered unserviceable by either normal fair wear or by aging and will
subsequently be repaired, modified, or condemned as appropriate. Equipment that is uneconomically
repairable (outdated) will be condemned. Disposition of air delivery equipment that is condemned,
unserviceable, or for which the serviceability is questionable, will be accomplished using the following
procedures, as applicable:
1. Item requiring repair or modification. An air delivery item that requires repair or modification will be
tagged in accordance with DA PAM 738-751. Subsequent work on the item will be performed at the
maintenance level specified for the maintenance function in the applicable supporting technical
publication and noted in the parachute log record.
2. Parachutes with exhausted age or service life. Any parachute component or air delivery equipment
whose age or service life has expired as specified in TB 43-0002-43 will be removed from service,
0009-3
TM 10-1670-276-23&P
0009
condemned, and tagged as prescribed by DA PAM 738-751.
3. Disposition of condemned air delivery equipment. Condemned equipment, other than fatality
parachutes, will be removed from service and disposed of in accordance with current directives listed
in this Work Package.
4. Rejected equipment. Equipment which, prior to use, is deemed unserviceable for use will be reported
in a PQDR in accordance with DA PAM 750-8, as authorized by AR 750-1. Each applicable item that is
defective will be held and safeguarded pending receipt of disposition instructions from the National
Maintenance Point (NMP). In all instances, PQDR exhibit material will be handled as prescribed in DA
PAM 750-8. If the quality or the serviceability of an item is questionable, clarification and assistance
may be obtained by contacting Commander, TACOM-LCMC, ATTN: AMSTA-LC-SECT, 15 Kansas
Street, Natick, MA 01760-5052.
5. Equipment of doubtful serviceability. Equipment that has had previous use and has not exceeded
normal fair wear or aging criteria, but of which further serviceability is doubtful, will be tagged as
prescribed in DA PAM 738-751. In addition, the equipment will be reported in an EIR, in accordance
with DA PAM 750-8 and AR 750-1. The item(s) in question will be held as EIR exhibit material as
outlined in DA PAM 750-8, pending receipt of disposition instructions from the NMP. A maintenance
activity holding EIR exhibit material will not tamper with the applicable item(s) or make any attempt to
ascertain cause factors. Unnecessary handling of EIR exhibit material may disturb or alter peculiar
aspects of the affected item(s) that might affect the judgment of engineering personnel who have the
responsibility for final evaluation of EIR actions. If the quality or the serviceability of an item is
questionable, clarification and assistance may be obtained by contacting Commander, TACOM-LCMC,
ATTN: AMSTA-LC-SECT, 15 Kansas Street, Natick, MA 01760-5052.
6. Equipment immersed in salt water. Any air delivery item constructed from cotton material that has
been immersed in salt water will be condemned. Cotton thread used for tacking and sewing on nylon
parachute packs that have been immersed in salt water will only be replaced when there is visible
evidence or deterioration, such as extreme discoloration or indications of broken thread. Any air
delivery equipment constructed of nylon or rayon material that has been immersed in salt water for a
period less than 24 hours, but which cannot be rinsed within 48 hours after recovery, will also be
condemned. However, if the cited time limitations can be met, then immediately, upon recovery,
suspend or elevate the recovered equipment in a shaded area and allow the item(s) to drain for at least
5 minutes. Do not attempt to wring the equipment fabric or the suspension lines. Within 48 hours after

The parachute shall be repacked every 365 days.
INSPECTION
If defects or damages are discovered during inspection of a parachute, the parachute must be rigger-rolled
and processed for maintenance in accordance with DA PAM 738-751. A technical/rigger-type inspection and
a pack-in-process inspection must be performed in conjunction with the packing of each parachute.
1. Technical/rigger-type inspection. Before each parachute is packed by air delivery, it must be given a
technical/rigger-type inspection by the packer in accordance with WP 0009.
2. Pack-in-process inspection. A designated supervisory rigger, other than the packer, must perform a
pack-in-process inspection at seven (7) intervals during the packing procedure. The inspection is
performed to ensure that the parachute is packed according to authorized packing procedures (refer to
WP 0009).
END OF TASK
ORIENTATION
Throughout this manual, all directions (right, left, upper, lower, top, bottom, clockwise, and counterclockwise)

1. Place packing tools in convenient locations on the packing table.
2. Lay the canopy assembly lengthwise on the packing table and attach the bridle loop to the packing
table apex hook.
Figure 2. Canopy Attached to Packing Table Apex Hook.
NOTE
When inversion, turns, tangles, and twists are present in the canopy
assembly, the proper sequence for removal, to achieve proper layout, is to
remove an inversion first, remove turns secondly, then remove tangles, and,
finally, remove twists.
END OF TASK
REMOVING INVERSION
To remove an inversion, proceed as follows:
1. Canopy inversion. Check canopy vent lines to determine if canopy has been inverted. Canopy is
inverted when vent lines are located inside upper lateral band (Figure 2). Remove inversion as
follows:

STITCHING AND RESTITCHING
Perform stitching and restitching as follows; refer to Tables 1 and 2.
1. Parachute canopy assemblies. The stitching and restitching made on parachute canopies should be
accomplished with thread that is contrasting in color to the fabric being restitched. If contrasting color
thread is not available, thread of matching color may be used, providing all other specifications are
met. Straight stitching and restitching on parachute canopy assemblies should be locked by at least 2
inches at each end of a stitch row, when possible. Zig-Zag stitching does not require locking;
however, zig-zag restitching should extend at least ¼ inch into undamaged stitching at each end,
when possible. When restitching parachute canopy assemblies, stitch directly over the original
stitching and follow the original stitch pattern as closely as possible.

(Refer to Tables 1 and 2). Darning is a sewing procedure used to repair limited size holes, rips, and tears.
A darning repair may be made either by hand or by sewing machine, depending upon the method
preferred and the availability of equipment. However, a darning machine should be used to darn small
holes and tears where fabric is missing. A darning repair will be performed using the following
procedures, as appropriate:
1. Machine darning. Proceed as follows:
a. Using an authorized marking aid of contrasting color, mark a square around the damaged area
and ensure the marking is at least ¼-inch back from each edge of the damaged area.
b. Darn the damaged area by sewing the material in a back and forth manner, using size A or E
nylon thread.
c. Turn the material and stitch back and forth across the stitching made in b., above, until the hole
or tear is completely darned.

ZIG-ZAG SEWING
(Refer to Tables 1 and 2). Components of the 26-Foot Diameter, High-Velocity Cargo Parachute, except
the parachute canopy, that have sustained cut or tear damage, may be repaired by zig-zag sewing,
provided the applicable damaged area does not have any material missing and the cut or tear is straight or
L-shaped. Should the damaged area be irregular shaped or have material missing, the repair will be
achieved by either darning or patching, as required. A zig-zag sewing repair will be accomplished using a
zig-zag sewing machine, with the following procedures:
1. Set the sewing machine to the maximum stitch width.
2. Beginning at a point ¼-inch beyond one end of the cut or tear, stitch lengthwise along the damaged
area to a point ¼-inch beyond the opposite end of the cut or tear.

CAUTION
Cotton tape, webbing, or cord will not be seared.
NOTE
Fabric materials such as cord, tape, and webbing, that are cut for
use in the maintenance of the 26-Foot Diameter, High-Velocity
Cargo Parachute, will normally be heat-seared or dipped in a melted
wax mixture, as applicable, to prevent the material from fraying or
unraveling. However, in some instances, the preparation of the
material may not be necessary and will be specified accordingly.
SEARING
The cut ends of nylon tape, webbing and cord lengths may be prepared by heat-searing, which is
performed by pressing the raw end of the material against a hot metal surface (knife) until the nylon has
melted sufficiently. Avoid forming a sharp edge or lumped effect on the melted end.
END OF TASK
WAXING
The fraying or unraveling of cotton or nylon tape, webbing, and cord length ends may be prevented by
dipping ½ inch of the raw end of the material into a thoroughly melted mixture of half beeswax and half
paraffin in an electric melting pot. The wax temperature should be substantial enough to ensure the wax
completely penetrates the material, rather than just coating the exterior fabric.

NOTE
Repair and/or replacement of a gore section is accomplished at the
Intermediate (Field) Maintenance Level only, in accordance with the
Maintenance Allocation Chart (MAC), WP 0049.
REPAIR
1. Restitching. Stitching and restitching made on parachute canopies should be accomplished with
size E or A nylon thread that is contrasting in color to the fabric being stitched or the original thread
being restitched. If contrasting color thread is not available, thread of matching color may be used,
providing all other specifications are met. Straight stitching and restitching should be locked by at
least two inches at each end of a stitch row, when possible. Zig-zag restitching should extend at
least ¼ inch into undamaged stitching at each end, when possible. Restitch directly over the
original stitching and follow the original stitch pattern as closely as possible.
2. Darning. Darn a hole or tear in a gore section which does not exceed ¾ inch in length or diameter
as prescribed in WP 0012, using size E or A nylon thread. There is no limit to the number of darns
which may be made on a gore section.
3. Patching. Use a patch to repair holes which exceed ¾ inch in length or diameter, using either the
sewn patch or the pressure-sensitive patch methods.
0034-1
TM 10-1670-276-23&P
0034
NOTE
The following limitations apply to the 26-foot cargo parachute.
The limitations prescribed for parachute canopy patching will be
stringently adhered to under all circumstances and without any
deviations:
A patch will not be applied to a damaged area that has been
previously patched.
There is no limitation to the number of patches or size of patch
to each canopy gore section or gore panel. However,
determination should be made as to the most economical method
to be used, i.e., two or more patches versus one large patch or
one large patch versus a section replacement.
A patch applied to a parachute canopy may extend from radial seam
to radial seam.
4. Sewn Patches. There are two types of sewn patches authorized, the basic and
miscellaneous. A basic patch is used to repair damaged cloth when the affected area is no
closer than 1 inch from a radial tape, vent reinforcement tape or skirt reinforcement tape.
Should a damaged area be closer than 1 inch to the cited areas, a miscellaneous patch will
be made.
NOTE
Sewn patches on the canopy will be applied to the inside and may be
square or rectangular in shape.
When a miscellaneous canopy patch is used, cut stitching and remove or
lay aside items which may interfere with patch application. Refer to
applicable item repair paragraph for proper procedures.
a. Using an authorized marking aid of contrasting color, mark a square or rectangle around
area to be patched and ensure one side of marked square or rectangle is parallel to warp or
fill of fabric.
b. Cut damaged area of fabric along lines made in paragraph 1 above. Further, cut fabric
diagonally at each corner to allow a ½-inch foldback in raw edges. Cut stitching and lay
aside or remove any item which will interfere with miscellaneous patch application.
c. Make ½-inch foldback on each raw edge. Pin and baste each foldback to complete
prepared hole. Basting will be performed using procedures in WP 0012.
d. Using 3.5-ounce muslin cloth, mark and cut a patch 2½ inches wider and longer than inside
measurements of prepared hole. Ensure patch material is marked and cut along warp or
fill of fabric.
e. Center patch material over prepared hole and ensure warp or fill of patch material
matches warp or fill of fabric being patched. Pin patch material in position.
f. Make ½-inch foldunder on each edge of patch material and baste patch to prepared area.
Basting will be performed using procedures in WP 0012.
g. Remove pincushions securing item to the repair table and secure patch by stitching, using
the applicable details in Figure 1, and stitching specifications outlined in Table 3, WP 0012.
Make first row of stitching completely around patch; invert canopy and make a second row
of stitching around prepared hole. Stitching will be performed in accordance with WP 0012.
h. Replace items removed for miscellaneous patch, as required, in accordance with
applicable item procedures.

5. Pressure-sensitive (iron-on) patch. This method of applying a basic patch is a heat and pressure
(iron-on) technique using pressure-sensitive coated cotton balloon cloth. This method is limited to
use on the cotton muslin canopies, such as the 26-foot cargo parachute. A complete canopy
section replacement will be performed when an individual section has been patched extensively
with the pressure-sensitive patch material and an apparent stiffening of the section occurs. The
stiffening effect may adversely affect the proper layout and packing of a parachute canopy. Apply a
pressure-sensitive (iron-on) patch as follows:
a. Smooth all wrinkles from materials surrounding the damaged area.
b. Cut a piece of pressure-sensitive coated cotton balloon cloth large enough to extend 1 inch
beyond all edges of the damaged area. If damaged area extends to a point within 1 inch of
upper lateral band, only a sewn patch, as outlined in Figure 1, B, will be allowed.
c. Place coated cloth patch over damaged area with adhesive side facing down. If damaged
area has no material missing, patch will be applied to the inside of canopy only. Whenever
damaged area has a space between the edges of material which indicates that material is
missing, patch will be applied to both inside and outside of canopy (Figure 2).
d. Using a household-type electric iron with heat regulated for cotton material, apply heat and
pressure simultaneously to patch material for at least 30 seconds. Ensure that all of patch
material is subjected to heat and pressure and that all edges of patch have adhered to
canopy material. Also, ensure that temperature of iron remains constant during patch
application effort and that no other part of canopy is underneath area being patched.
6. Restenciling. As required, restencil identification markings using procedures in WP 0014.
END OF TASK

NOTE
When replacing gore sections, use 3.5 ounce cotton muslin cloth
of same color as that being replaced. If the same color cloth is not
available, another color may be used. When replacing section 1 of
gore 1, restencil gore number and information data block on replacement
section. For other gores, stencil gore numbers as necessary using
procedures in WP 0014. A gore section which is damaged beyond repair
will be replaced as follows:
1. Gore section 1.
a. Cut a piece of 3.5-ounce cotton muslin cloth 2 ½ inches longer and 1 ½ inches wider
than original gore section (Figure 3).
b. Place cut material over damaged area and using a suitable marking device, trace
outline of original gore section, including width of radial tapes on each side of damaged
area and width of skirt reinforcement tape (lower lateral band) at bottom. Allow material to
extend 1 inch beyond original gore section upper edge, 1½ inches below lower skirt

SERVICE MAINTENANCE
26-FOOT DIAMETER, HIGH-VELOCITY CARGO PARACHUTE ASSEMBLY
PREPARATION FOR STORAGE OR SHIPMENT
0037
Storage Criteria
Administrative storage of air delivery equipment will be accomplished in accordance with AR 750-1
and the instructions furnished below.
General Storage Requirements
To ensure that stored air delivery equipment serviceability standards are maintained, every effort will
be made to adhere to the following storage requirements:
1. When available, a heated building should be used to store parachutes and other air delivery items.
2. Air delivery equipment will be stored in a dry, well-ventilated location and protected from pilferage,
dampness, fire, dirt, insects, rodents, and direct sunlight.
3. Air delivery equipment will not be stored in a manner which would prevent ventilation or interfere
with light fixtures, heating vents, fire-fighting devices, cooling units, exits, or fire doors.
4. Air delivery items will not be stored in a damaged, dirty, or damp condition.
5. All stored air delivery items will be marked, segregated, and located for accessibility and easy
identification.
6. Air delivery equipment will not be stored in direct contact with any building floor or wall. Storage will
be accomplished using bins, shelves, pallets, racks or dunnage to provide airspace between the
storage area floor and the equipment. If preconstructed shelving or similar storage
accommodations are not available, locally fabricate storage provisions using suitable lumber or
wooden boxes.
7. All available materials handling equipment should be used as much as possible in the handling of
air delivery items.
8. Periodic rotation of stock, conversion of available space, proper housekeeping policies, and strict
adherence to all safety regulations will be practiced at all times.
Storage specifics for parachutes. In addition to the storage requirements stipulated above,
following is a list of specific requirements that must be enforced when storing parachutes:
(1) Except for those assemblies required for contingency operation, parachutes will not be
stored in a packed configuration.
(2) Stored parachute assemblies will be secured from access by unauthorized personnel.
(3) A parachute which is in storage, and is administered a cyclic repack and inspection, will not be
exposed to incandescent light or indirect sunlight for a period of more than 36 hours. Exposure to
direct sunlight should be avoided entirely.
In-Storage Inspection
General Information. An in-storage inspection is a physical check conducted on a random sample of
parachutes which are located in storage.
Intervals. Parachutes in storage will be inspected at least semiannually and at more frequent
intervals if prescribed by the local Airdrop Systems Technician (921A) or Senior Airdrop NCO (92R4P)
0037-1
TM 10-1670-276-23&P
0037
and above, under guidance from an Airdrop Systems Technician assigned to the command at the
Battalion level or higher, when no Airdrop Technician is assigned at the Company/Detachment/Team
level.
Inspection. Inspect to ensure that the parachute is ready for issue.
(1) Check the parachute for proper identification.
(2) Check for damage or deterioration.
(3) Ensure that all modifications or similar requirements have been completed.
(4) Check the adequacy of the storage facilities, efforts taken to control pests and rodents, and
protection against unfavorable climatic conditions.
Shipment
Initial Shipment. The initial packaging and shipping of parachutes is the responsibility of item
manufacturers, who are required to comply with federal and military packing specification as stipulated
in contractual agreements. Air delivery equipment is normally shipped to depot activities by domestic
freight or parcel post, packaged to comply with overseas shipping requirements. Except for those air
delivery items which are unpackaged and subjected to random inspections or testing by a depot
activity, parachutes received by a using unit will be contained in original packaging materials.
Shipping Between Maintenance Activities. The shipping of air delivery equipment between
organizational and direct support maintenance activities will be accomplished on a signature
verification basis using whatever means of transportation are available. Used parachutes and other
fabric items will be tagged in accordance with DA PAM 738-751, and rolled, folded or placed loosely in
a parachute pack, deployment bag, or other suitable container, as required. Used wood and metal air
delivery items will be tagged as prescribed in DA PAM 738-751 and placed in a suitable type
container, if necessary. Unused air delivery equipment will be transported in original shipping
containers. During shipment, every effort will be made to protect air delivery equipment from weather
elements, dust, dirt, oil, grease and acids. Vehicles used to transport parachutes will be inspected to
ensure the items are protected from the previously cited material-damaging conditions.
Other Shipping Instructions. Air delivery equipment destined for domestic or overseas shipment will
be packaged and marked in accordance with AR 700-15 (Packaging of Materiel).
Accordion Folding and Rigger Rolling
Accordion Folding. Parachute canopy assemblies that are not packed for use should be accordion
folded prior to entry into storage. To accordion fold a parachute canopy assembly, perform the
following:
(1) Place the parachute canopy in proper layout under partial tension and dress the outside edges of
both gore groups.
(2) Fold the left group of gores over the right group of gores (Figure 1, A). Release tension.
0037-2
TM 10-1670-276-23&P
0037
(3) “Chain” the suspension lines and S-fold the “chained” lines on top of the deployment bag (Figure
1, B).
(4) Place the lower end of the canopy on top of the S-folded suspension lines and locate the lower
edge of the canopy skirt at the lower end of the deployment bag.
(5) Accordion fold the remaining canopy length neatly on top of the canopy lower end (Figure 1, C).
Turn the canopy vent under the last fold.
(6) Temporarily secure the folded canopy to the deployment bag with available webbing (Figure 1, D).
(7) Upon completion of the accordion folding process, place the folded parachute assembly in a
suitable type container for storage.

Rigger Rolling. Parachute assemblies will be rigger rolled, prior to being sent to or returned from a
parachute repair activity, for ease of handling to prevent suspension line entanglement. Rigger roll a
parachute as follows:
(1) Place the parachute in proper layout and apply partial tension.
(2) Grasp the right and left suspension line groups. Using a fast, circular motion, flip each of the two
gore groups up and to the center radial seam. Tighten each gore group roll by hand and bring
both rolled gore groups together at the center radial seam (Figure 2, A).
(3) Release tension and disconnect the canopy vent from the vent attaching device.
(4) Fold the canopy vent down between the rolled gore groups to a point within 18 inches of the
canopy skirt lower edge.
(5) Beginning at the folded upper end of the canopy, roll the canopy tightly toward the canopy skirt
(Figure 2, B). Ensure the width of the rolled canopy does not exceed the width of the parachute
deployment bag.
(6) Continue rolling the canopy toward the lower end of the suspension lines and risers, locating the
lines and riser webbing around the center of the roll (Figure 2, C).
(7) Disconnect the suspensions lines/risers form the attaching device and place the rolled canopy
assembly on top of the deployment bag.

subassembly groups, and lists are divided into the same groups.
Second. Find the figure covering the functional group or the subfunctional group to
which the item belongs.
Third. Identify the item on the figure and note the number(s).
Fourth. Look in the repair parts list work packages for the figure and item numbers. The
NSNs and part numbers are on the same line as the associated item numbers.
2. When NSN Is Known.
First. If you have the NSN, look in the STOCK NUMBER column of the NSN index
work package. The NSN is arranged in NIIN sequence. Note the figure and item
number next to the NSN.
Second. Turn to the figure and locate the item number. Verify that the item is the one
you are looking for.
3. When Part Number Is Known.
First. If you have the part number and not the NSN, look in the PART NUMBER
column of the part number index work package. Identify the figure and item number.
Second. Look up the item on the figure in the applicable repair parts list work package.

MAINTENANCE ALLOCATION CHART
MAINTENANCE ALLOCATION CHART (MAC)
INTRODUCTION
The Army Maintenance System MAC
This introduction provides a general explanation of all maintenance and repair functions authorized at the
two maintenance levels under the Two-Level Maintenance System concept.
This MAC (immediately following the introduction) designates overall authority and responsibility for the
performance of maintenance functions on the identified end item or component. The application of the
maintenance functions to the end item or component shall be consistent with the capacities and
capabilities of the designated maintenance levels, which are shown on the MAC in column (4) as:
Field - includes three subcolumns, Crew (C), Service (O), and Field (F).
Sustainment – includes two subcolumns, Below Depot (H) and Depot (D).
The maintenance to be performed below depot and in the field is described as follows:
1. Service maintenance. The responsibility of a using organization to perform maintenance on its
assigned equipment. It normally consists of inspecting, servicing, lubricating, adjusting, and replacing
parts, minor assemblies, and subassemblies. The replace function for this level of maintenance is
indicated by the letter “O” in the third position of the SMR code. An “O” appearing in the fourth
position of the SMR code indicates complete repair is possible at the service maintenance level.
2. Field maintenance. Maintenance accomplished on a component, accessory, assembly,
subassembly, plug-in unit, or other portion, either on the system or after it is removed. The replace
function for this level of maintenance is indicated by the letter “F” appearing in the third position of the
SMR code. An “F” appearing in the fourth position of the SMR code indicates complete repair is
possible at the field maintenance level. Items are returned to the user after maintenance is
performed at this level.
3. Below Depot sustainment. Maintenance accomplished on a component, accessory, assembly,
subassembly, plug-in unit, or other portion, either on the system or after is removed. The replace
function for this level of maintenance is indicated by the letter “H” appearing in the third position of the
SMR code. An “H” appearing in the fourth position of the SMR code indicates complete repair is
possible at the below depot sustainment maintenance level. Items are returned to the supply system
after maintenance is performed at this level. The tools and test equipment requirements table
(immediately following the MAC) lists the tools and test equipment (both special tools and common
tool sets) required for each maintenance function as referenced from the MAC. The remarks table
(immediately following the tools and test equipment requirements) contains supplemental instructions
and explanatory notes for a particular maintenance function.
Maintenance Functions
Maintenance functions are limited to and defined as follows:
1. Inspect. To determine the serviceability of an item by comparing its physical, mechanical, and/or
electrical characteristics with established standards through examination (e.g., by sight, sound, or
feel.) This includes scheduled inspection and gaugings and evaluation of cannon tubes.
0049-1
TM 10-1670-276-23&P
0049
2. Test. To verify serviceability by measuring the mechanical, pneumatic, hydraulic, or electrical
characteristics of an item and comparing those characteristics with prescribed standards on a
scheduled basis, i.e., load testing of lift devices and hydrostatic testing of pressure hoses.
3. Service. Operations required periodically to keep an item in proper operating condition, e.g. to
clean (includes decontaminate, when required), to preserve, to drain, to paint, or to replenish fuel,
lubricants, chemical fluids, or gases. This includes scheduled exercising and purging of recoil
mechanisms. The following are examples of service functions:
a. Unpack. To remove from packing box for service or when required for the performance of
maintenance operations.
b. Repack. To return item to packing box after service and other maintenance operations.
c.
Clean. To rid the item of contamination.
d. Touch up. To spot paint scratched or blistered surfaces.
e. Mark. To restore obliterated identification.
4. Adjust. To maintain or regulate, within prescribed limits, by bringing into proper position, or by
setting the operating characteristics to specified parameters.
5. Align. To adjust specified variable elements of an item to bring about optimum or desired
performance
6. Calibrate. To determine and cause corrections to be made or to be adjusted on instruments of
test, measuring, and diagnostic equipment used in precision measurement. Consists of
comparisons of two instruments, one of which is a certified standard of known accuracy, to detect
and adjust any discrepancy in the accuracy of the instrument being compared.
7. Remove/Install. To remove and install the same item when required to perform service or other
maintenance functions. Install may be the act of emplacing, seating, or fixing into position a
spare, repair part, or module (component or assembly) in a manner to allow the proper functioning
of an equipment or system.
8. Paint (ammunition only). To prepare and spray color coats of paint so that the ammunition can be
identified and protected. The color indicating primary use is applied, preferably, to the entire
exterior surface as the background color of the item. Other markings are to be repainted as
original so as to retain proper ammunition identification.
9. Replace. To remove an unserviceable item and install a serviceable counterpart in its place.
“Replace” is authorized by the MAC and assigned maintenance level is shown as the third position
code of the Source, Maintenance and Recoverability (SMR) code.
10. Repair. The application of maintenance services, including fault location/troubleshooting,
removal/installation, disassembly/assembly procedures and maintenance actions to identify
troubles and restore serviceability to an item by correcting specific damage, fault, malfunction, or
failure in a part, subassembly, module (component or assembly), end item, or system.
0049-2
TM 10-1670-276-23&P
0049
NOTE
The following definitions are applicable to the “repair” maintenance function:
Services. Inspect, test, service, adjust, align, calibrate, and/or replace.
Fault location/troubleshooting. The process of investigating and detecting the cause
of equipment malfunctioning; the act of isolating a fault within a system or Unit
Under Test (UUT).
Disassembly/assembly. The step-by-step breakdown (taking apart) of a
spare/functional group coded item to the level of its least component, that is
assigned an SMR code for the level of maintenance under consideration (i.e.
identified as maintenance significant).
Actions. Welding, grinding, riveting, straightening, facing, machining, and/or
resurfacing.
11. Overhaul. That maintenance effort (service/action) prescribed to restore an item to a completely
serviceable/operational condition as required by maintenance standards in appropriate technical
publications. Overhaul is normally the highest degree of maintenance performed by the Army.
Overhaul does not normally return an item to like new condition.
12. Rebuild. Consists of those services/actions necessary for the restoration of unserviceable
equipment to a like new condition in accordance with original manufacturing standards. Rebuild
is the highest degree of material maintenance applied to Army equipment. The rebuild operation
includes the act of returning to zero those age measurements (e.g., hours/miles) considered in
classifying Army equipment/components.
Explanation of Columns in the MAC
Column (1) Group Number. Column (1) lists Functional Group Code (FGC) numbers, the purpose of
which is to identify maintenance significant components, assemblies, subassemblies, and modules with
the Next Higher Assembly (NHA).
Column (2) Component/Assembly. Column (2) contains the item names of components, assemblies,
subassemblies, and modules for which maintenance is authorized.
Column (3) Maintenance Function. Column (3) lists the functions to be performed on the item listed in
column (2). (For a detailed explanation of these functions refer to “Maintenance Functions” outlined
above).
Column (4) Maintenance Level. Column (4) specifies each level of maintenance authorized to perform
each function listed in column (3), by indicating work time required (expressed as manhours in whole
hours or decimals) in the appropriate subcolumn. This work time figure represents the active time
required to perform that maintenance function at the indicated level of maintenance. If the number or
complexity of the tasks within the listed maintenance function varies at different maintenance levels,
appropriate work time figures are to be shown for each level. The work time figure represents the average
time required to restore an item (assembly, subassembly, component, module, end item, or system) to a
serviceable condition under typical field operating conditions. This time includes preparation time
(including any necessary disassembly/assembly time), troubleshooting/fault location time, and quality
assurance time in addition to the time required to perform the specific tasks identified for the maintenance
functions authorized in the MAC. The symbol designations for the various maintenance levels are as
follows:

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly
available information, slap “watermarks” and other junk on it, and sell it.
Those masters of search engine manipulation make sure that their sites that
sell free information, come up first in search engines. They did not create it...
They did not even scan it... Why should they get your money? Why are not
letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US
Government and is NOT protected by Copyright. Feel free to share,
republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please
provide a link to liberatedmanuals.com, so that free manuals come up first in
search engines:
