LIFE PRESERVER
2.3.1
The life preserver cover (see figure 29) is attached directly to the survival vest with an
interlocking (Dutch style) speed lacing loop system (see figure 4) and is easily removable. The
life preserver consists of two major components:
a. Inflatable Cell
b. Protective Container
2.3.2
The inflatable cell is attached to the Survival Vest at three points; one directly to the protective
container by means of a short speed lacing loop system at the rear. The other two direct
attachment points are where the webbing straps attach to the front lobes. The free end of the
Survival Vest anchor strap passes through the slots on the back side the protective cover and
through the inflatable cell grommets (1.0 inch (25 mm) plastic grommets RF bonded in place),
located at the lower points of the cell lobes. A ‘lift the dot’ snap is used to secure them in
place. The inflatable cell, when folded, is contained within the protective container by means of
a perimeter zipper closure system and a Velcro patch located at the rear at the zipper ends.
2.4
INFLATABLE CELL
2.4.1
The inflatable cell is made from polyurethane coated nylon fabric and is yellow in colour. The
perimeter of the cell is sealed using radio frequency (RF) bonding.
NOTE: All location reference points in this section are based from the perspective of
the person wearing the LP/SV.
2.4.2
The inflatable cell comprises two independent chambers, front and rear, which are created by
the provision of a separate ply of unsupported polyurethane film between the outer panels of
4

the cell. This ply forms a floating baffle, which is free to move between the front and rear
panels depending on the gas volume in each chamber.
WARNING: The MSV971 is configured with a manual inflation system and will not
automatically inflate when immersed in water.
2.4.3
Normal manual inflation by carbon dioxide gas (CO2), fully inflates the rear chamber. The front
chamber may be inflated by mouth only, and provides for redundancy in an event where the
rear chamber becomes damaged or requires topping up.
2.4.4
When inflated, the cell forms a yoke around the back of the user's neck, extending into two
lobes down the user's chest.
2.4.5
A cell anchor strip is permanently attached to the rear panel of the inflatable cell to permit
attachment of the cell to the protective container by means of an interlocking (Dutch style)
speed lacing loop system.

MANUAL CO2 INFLATION DEVICE
The MSV971 is an appropriate platform for a wide variety of customized LP/SV units to address user
requirements that include:
•
use in ejection seat fitted aircraft
•
use with an automation inflation device
•
stowage of unique pieces/combinations of survival equipment
Contact Mustang Survival for further details.
2.5.1
Life preservers, which are intended for use in non-ejection seat, equipped aircraft incorporate
a manually operated inflation device. The operating components of the manual inflation device
(Halkey-Roberts HD77189 840 AMLS INFLATOR) are shown in figure 5.
Figure 5. Manual CO2 Inflation Device – Non-Operated/Ready Position

2.5.2
The manual inflation device is located on the rear left lobe of the inflatable cell. The inflation
device is secured with a cap nut to the manifold valve, which in turn is RF bonded to the
inflatable cell. A 34-37 gram carbon dioxide (CO2) cylinder is threaded into the top of the
inflation device, and is secured against the cell with a looped nylon elastic retaining strap. The
beaded inflation handle is attached with a lanyard to the operating lever of the inflation device,
which in turn is safety tied by inserting and tying a red cotton witness thread through the hole
in the operating lever and through the hole in the body of the inflation device.
2.6
BEADED CO2 INFLATION HANDLE
2.6.1
The beaded inflation handle is constructed of six plastic beads threaded onto a loop of nylon
webbing. The handle is attached with a lanyard to the operating lever of the CO2 inflation
device and is fixed with Velcro™ to the back side of the left lobe of the protective container.

The beaded handle is designed to provide a positive grip for inflation of the preserver with
cold, wet or gloved hands.
2.7
ORAL INFLATOR
2.7.1
Two oral inflator valve assemblies are attached to the inflatable cell. Each oral inflator valve
assembly consists of an oral inflation valve mounted in an oral inflation tube, which in turn is
RF bonded to the inflatable cell. Both oral inflators are secured against the cell with a Velcro™
retaining strap. Each oral inflator accesses a separate chamber.
2.7.2
The oral inflator located on the front left lobe of the inflatable cell inflates/deflates the front
chamber. This inflator is used in the event that the rear inflatable chamber becomes damaged
or if the other chamber fails to inflate. When the inflatable cell is stored (packed), this inflator
valve is locked in the open position for use as back-up in an emergency.
2.7.3
The oral inflator located on the rear right lobe of the inflatable cell inflates/deflates the rear
inflatable chamber. This inflator provides an alternate means of inflation in the unlikely event
that the manual or automatic inflation device malfunctions. When the inflatable cell is stored
(packed), this inflator valve is locked in the closed position to prevent venting during inflation.
2.7.4
Both inflators also provide a means of "topping up" the cell to compensate for normal leakage
or under-inflation due to excessively cold temperatures. As well, these oral inflators provide a
means for cell deflation.
2.8
PROTECTIVE CONTAINER
2.8.1
The protective container is constructed of flame retardant aramid Nomex cloth, sage green in
color. It is attached directly to the survival vest with a speed lacing loop system. The container
houses the inflatable cell, providing a compact, flame resistant protective enclosure.
2.8.2
The un-inflated cell is attached directly to the inside of the protective container with a speed
lacing loop system. The cell is neatly folded and packed within the container, which in turn is
secured in the closed position with a system of slide fasteners, and a Velcro™ tab. The tail
ends of the slide fastener tapes are protected by 'tucking' the tails into the lower openings of
the secured container to prevent premature opening.
2.8.3
The container’s slide fastener closure is closed with separate sliders, which are stowed and
secured with a lanyard inside the pockets located on the inside of the survival vest.
2.8.4
The inflation handle lanyard passes through the upper reinforced opening at the rear left of the
container and Velcro™ attaches the beaded inflation handle to the underside of the protective
container. The anchor straps for the lobes of the inflatable cell pass through the lower
reinforced openings in the protective container.
2.8.5
Inflation of the life preserver, forces the fasteners around the periphery of the container to
separate, allowing the cell to reach its fully inflated shape.

2.9.2
The survival vest is a waistcoat style vest constructed of sage green, flame retardant, Nomex
cloth and mesh. The vest incorporates six outside pockets and four inside pockets, for the
stowage of personal survival equipment. Customers may contact Mustang Survival to select
different pocket configurations.
2.9.3
Also provided are two rings located on the front of the vest, between the lobes of the protective
container. These rings are meant to provide a suitable attachment point for reducing the
hanging weight of mask/helmet-mounted equipment (i.e. chemical protective canisters)
relieving stress to the neck.
2.9.4
The vest is donned and secured at the front with a large black nylon entry zipper and a waist
buckle. A snap tab is provided at the top, to retain the zipper slider tab and, to ensure that the
zipper remains secured in windblasts. The waist belt and side adjustment straps provide
adjustment.
2.9.5
A series of life preserver attachment loops, constructed of loops of sage green, fire retardant
®
Nomex cord, are sewn into a folded nylon tape strip, which is secured down the front left and
front right chest area, and across the upper back, below the neck. These loops provide a
means for attachment of the life preserver protective container.

2.10
RESCUE HARNESS SYSTEM
2.10.1
The vest incorporates a rescue harness system, consisting of a left side and right side harness
handle loop. The harnesses are sewn directly to the outside of the vest, and are constructed of
sage green nylon webbing, folded and stitched over a stainless steel reinforcement cable
which is used only to maintain the loop shape of the harness. Both sides should be used
simultaneously during lifting.
2.10.2
The side adjustment straps are located on the left and right sides of the survival vest, just
below the arm openings. The side adjustment straps provide both preliminary and final wearer
adjustment for use, both prior to and after water entry.
2.10.3
The harness handle loops are fed through the upper reinforced slot opening in the protective
container and stored underneath the folded cell. Velcro™ deployment lines attach the top of
each handle loop that attaches to the inflatable cell so that the lines are readily accessible
after inflation.
WARNING: Failure to do this will cause the harness system to be inoperative and could
only be used after the inflatable cell has been deflated.
2.10.4
Each harness has a strip of reflective tape stitched to the top of it for low-light rescues..
2.10.5
The (user’s) right hand harness has an attached buddy-line and whistle. These items are
stored in two looped nylon retaining straps fixed mid-way up the harness.
2.11
ADJUSTABLE WAIST BELT
2.11.1
The waist belt is constructed of 1 1/2 inch (38 mm) wide sage green nylon webbing. The belt is
secured at the front of the vest with a two-piece steel buckle. The belt provides both
preliminary wearer adjustment upon donning the LP/SV and a final adjustment just before or
after water entry.
2.11.2
The waist belt is stitched directly to the vest at the front left and at the right side, effectively
separating the belt into two adjustment areas.
2.11.3
Preliminary fit by adjusting the belt sliders, located at the rear of the vest, until the vest feels
comfortably snug.
2.11.4
Final/ongoing adjustment is accomplished by adjusting the buckle on the front of the belt after
donning. This adjustment is intended to ensure that the LP/SV remains well secured to the
wearer, reducing the potential for the vest to 'ride-up' on the wearer upon inflation of the life
preserver in water. Final adjustments are possible both prior to and after water entry.
2.12
SIDE ADJUSTMENT STRAPS
2.12.1
The side adjustment straps are constructed of one inch (25 mm) wide sage green acetyl nylon
webbing. One length of webbing forms the rear fixed ends, by looping through black nylon belt
adjusters, and sewing both free ends directly to the side of the vest.
2.12.2
Two lengths of webbing form the adjustment ends; with one end sewn to the front of the vest
and the free end passed through a nylon belt loop and looped through the belt adjuster, then is
folded and sewn into a T-tab for webbing retention.
2.12.3
Adjust by pulling on the T-tab. Loosen by lifting at the front of the nylon adjuster and pushing
the adjuster rearwards.

2.13
BALLISTIC LINER ATTACHMENT POINTS
2.13.1
The MSV971 has built-in provisions for adding an optional ballistic liner accessory to the inside
of the survival vest. The vest has two zippers running along the inside of the main opening and
a Velcro™ tab at the inner neck that secure the ballistic liner.
NOTE: Depending on the thickness of the liner used, switching to a larger sized
survival vest may be necessary when worn with a ballistic liner.
2.14
OPERATION
CAUTION: Over-pressurization will over-stress the inflatable cell. Both chambers of the
cell must be completely evacuated of any residual air or carbon dioxide gas
prior to CO2 inflation.
2.14.1
Manual operation of the life preserver is accomplished by grasping the beaded inflation handle
located on the lower left side of the protective container. Jerking sharply downwards rotates
the operating lever of the CO2 inflation device, which in turn forces the piercing pin to puncture
the neck of the CO2 cylinder and allow the compressed gas to flow into the inflatable cell.
The MSV971 is an appropriate platform for a wide variety of customized LP/SV units to address user
requirements that include:
•
use in ejection seat fitted aircraft
•
use with an automation inflation device
•
stowage of unique pieces/combinations of survival equipment

2.14.2
The pressure of the expanding gas forces the fasteners around the periphery of the protective
container to separate, automatically opening the protective container and allowing the cell to
reach its fully inflated shape.
NOTE: Carbon dioxide gas does not remain in the life preserver indefinitely. Either of
the oral inflator valves can be used as a means of compensating for normal cell
leakage. The oral inflators are also provided as an emergency back up in the
unlikely event that the CO2 inflation device fails.

b. Lay the LP/SV unit out on a flat, clean surface so that the completely deflated cell is
fully extended.
c. Ensure that the rescue harness loops are fed through the upper openings in the
protective container and laying flat underneath the cell. Check that the Velcro™
deployment lines are routed through the centre of the collar and connected the top of
the harness loops with the patch on the cell and also check that the buddy-line and
whistle are secured in place.
d. SIDE OPPOSITE TO MANIFOLD VALVE Screw shall be turned fully in the LOWER
(not locked) position. This would allow the user to, if needed, manually inflate the cell
without having to fumble with the lock.
e. MANIFOLD VALVE SIDE Screw shall be turned fully in the UPPER (locked)
position. Otherwise, as the cell is folded and packed and the inflator actuated, it is
possible that the cell itself may depress the valve as it inflates, permitting the escape
of gas.

g. Reassemble the LP/SV unit and perform the visual inspections as per section 5.3 above.
5.5
INFLATION MANIFOLD VALVE TEST
5.5.1
Test the core of the inflation manifold valve:
a. Remove the cap nut and the inflation device.
b. Ensure that the core of the valve is properly seated, and then inflate the cell to 2.0 psi
gauge or until the cell feels hard to the touch.
c. Place a small amount of soap & water solution over the valve opening. Bubbles in the
solution indicate leakage; replace the core. Alternatively, submerge the cell in fresh
clean cool water and look for bubbles.
5.6
ORAL INFLATOR VALVE TEST
5.6.1
Test both oral inflator valves for leaks:
a. With the opposite chamber evacuated completely, inflate the appropriate inflatable cell
chamber to a gauge pressure of 2.0 psi or until the cell feels hard to the touch.
b. Place a small amount of soap & water solution on the stem opening. Use care to prevent
the entry of water into the valve. A bubbling of the soap solution will indicate leakage.
c. To check the oral inflation valve for blockage; lower the pressure in the inflatable cell
chamber to 0.5 - 1.0 psig. Open the air passage by pushing the valve inwards and then
blow by mouth through the oral inflator valve. The effort required to inflate the chamber
should not be excessive and the valve must close tightly when the oral inflation is halted.
d. Consider the valve non-serviceable if it fails either test and replace it.
5.7
INFLATABLE CELL TEST
5.7.1
The inflatable cell consists of two independent inflatable chambers, both of which must be
tested. Prior to any inflatable cell chamber test, it is imperative that the opposite chamber is
first evacuated of all residual gas or air. The rear chamber can be accessed through the rear
oral inflator assembly and the CO2 inflation valve. The front chamber can be accessed through
the front oral inflator assembly only.
5.7.2
To test each chamber of the inflatable cell:
a. Remove the CO2 cylinder to prevent accidental double inflation.
b. Slowly inflate one of the cell chambers, through the oral inflation valve, using an oil free
pressurized airline. Inflate to a gauge pressure of 2.0 psi (140 cm/55 inches of water).
NOTE: If the cell being tested is a new item from stock, inflate the rear chamber of the
cell through the CO2 inflation device, rather than the oral inflation valve, to
ensure free airflow through the inflation device and manifold.
c. Allow ten minutes for pressure stabilization, then (if necessary) adjust the pressure back
to 2.0 psi gauge.

d. Hang the inflatable cell for six hours in an area where the ambient temperature can be
maintained at a constant 22°C (72°F).
e. The cell chamber is serviceable if, after the six-hour period, the internal pressure in
either chamber did not drop below 1.5 psi (corrected for temperature, if necessary).
Otherwise the cell is condemned and non-repairable.
NOTE: Both chambers must be serviceable before the inflatable cell is to be
considered usable.
f.
Evacuate the tested cell chamber completely of all residual air and repeat steps (a)
through (e) for the other cell chamber
g. If there is evidence of leakage in any of the valves, replace the suspect valve and repeat
steps (b) through (f).
5.8
CO2 INFLATION DEVICE TEST
5.8.1
To test the inflation device, and perform the following:
a. Remove the CO2 cylinder.
b. Ensure the cylinder seat-sealing gasket is in place.
c. Pull the beaded inflation handle and rotate the operating lever several times to ensure a
smooth, free operation.
d. Check that there is a minimum of a 3.0 mm protrusion of the piercing pin. This is
required to ensure that the piercing pin will pierce the CO2 cylinder-sealing disc when the
inflator valve is in the operated/activated position. If the protrusion is less than 3 mm, the
device must be replaced.
e. Return the operating lever to the non-operated "ready" position.
h. Replace the CO2 cylinder.
5.9
CO2 CYLINDER INSPECTION AND WEIGHT TEST
5.9.1
All carbon dioxide (CO2) cylinders should be weighed and inspected regardless of whether
they are new, or previously fitted cylinders that appear to be serviceable.
5.9.2
To inspect the cylinder, perform the following:
a. Weigh the cylinder with a scale, which is accurate to 0.1 gram. The measured weight
should not be lower than the gross weight stencilled on the cylinder. Cylinders not
meeting the gross weight specifications should be retained only for training or test
purposes and must be clearly marked "NOT FOR SERVICE USE".
b. Inspect the cylinder threads for damage, the cylinder surface for nicks, dents or
ballooning and the cylinder neck-sealing disc for scratches or punctures. Cylinders
showing any damage should have the gas released under control and then are disposed
of as scrap.
