General Information
Introduction
The P/N 200-302-00 Cargo Hook Kit is approved for installation on the BO-
105S model helicopter equipped with a suspension system installed per
American Eurocopter STC SH286NE and the P/N 200-387-00 cargo hook kit is approved for installation on a BO-105S or BO-105LS model equipped with a suspension P/N 117-80127. These kits replace the cargo hook, an adapter link assembly, the manual release cable and an external electrical release wire harness on the existing cable type suspension system. They utilize the existing cable suspension and internal electrical wiring.
The P/N 200-302-00 and P/N 200-387-00 kits are identical except for the adapter link assembly. The adapter link assembly serves to connect the cargo hook to the cable suspension shackles and is narrower in kit P/N 200-
387-00 to accommodate the shackles on the Siren suspension.

2.1 Master Cylinder Assembly Installation
The hydraulic release system is supplied dry. It is recommended that the system be filled and bled on the bench before installing on the helicopter.
Refer to section 2.6 for filling and bleeding instructions.
The Master Cylinder Assembly (P/N 232-208-01) installation consists of installing the master cylinder on the collective in the cockpit, and routing the attached hose to a bracket to be installed near the right forward suspension cable.
Observe the following precautions (ref. Figure 2.1.1) when routing the hydraulic hose.
Use care to avoid kinking the hose.
Recommended minimum hose bend radii is 1 inch. Avoid abrupt change in direction of the hose just outside the end fittings.
Provide smooth transitions where possible.
Verify that the hose routing is clear of and cannot be deflected into chafe points.
Figure 2.1.1 General Hose Routing Practices
Maximize bend radii
Use adel clamp and bracket (shown), ty-wraps, or other suitable means to secure hose at various points.

Installation Check-out
After installation of the Cargo Hook kit and before re-installing belly panels, perform the following functional checks.
1. Swing the installed Cargo Hook to ensure that the hydraulic release hose and the electrical release harness have enough slack to allow full swing of the suspension assembly without straining or damaging them. The hose and/or harness must not be the stops that prevent the Cargo Hook from swinging freely in all directions.
2. Verify that the hydraulic hose routing does not have kinks and is clear of chafing points.
3. Ensure that the collective has full movement and is not restricted by the hydraulic hose routing.
4. Pull the hydraulic release lever on the collective. The Cargo Hook load beam should open.
5. Close the cargo hook release circuit breaker and position the battery switch to the ON position. With no load on the cargo hook, depress the cargo hook electrical release button. The Cargo Hook load beam should open.
6. Pull the cargo hook up to the stowed position and latch it into the retainer sling.
Ensure hydraulic hose is free from chafing and kinking and that the electrical harness is protected by the spiral wrap from chafing on the retainer cable.

2.6 Filling Hydraulic Release System
Each hydraulic system is typically shipped dry. A label affixed to the Master
Cylinder and Slave Cylinder assemblies will state if each hydraulic assembly has been filled and bled. Proper bleeding is critical to the operation of the hydraulic release system. An improperly bled system will not release the cargo hook mechanism.
A reservoir seal is installed beneath the reservoir lid. This seal serves to prevent hydraulic fluid left over from the testing process from leaking during shipping.
The reservoir seal is for shipping purposes only and must be removed and discarded before bleeding or installation of the hydraulic release
system.
If there is a need to fill and/or bleed the system, follow the procedures listed below. If you need to remove and repair any items in the hydraulic system, refer to
123-022-00, Instruction for Continued Airworthiness.
Filling and bleeding the hydraulic release system is most easily accomplished on the bench, prior to installation on the aircraft. This process may also be accomplished after the system is installed. Filling and bleeding requires two persons, one to inject hydraulic fluid through the system and the other to observe the reservoir.
Following is the procedure:
1. Obtain the hydraulic hook bleed kit, 212-014-01. This kit consists of 2 ounces of MIL-PRF-5606 fluid, a syringe, a female barb fitting, a length of PVC tubing, and a bleed adapter fitting. The bleed kit is included in new Hydraulic Hook kits. Assemble the bleed kit by press fitting each component together.
2. If the system is already installed on the aircraft, place an absorbent towel under the master cylinder. If the master cylinder is not installed on the aircraft, lightly clamp the master cylinder in a vise to hold it in a vertical position and position the slave cylinder so that its level is below the level of the master cylinder.
Use best shop practices to keep foreign material out of the hydraulic system. FOD will plug orifices, damage seals and/or scratch sealing surfaces necessitating system rebuild. Use only clean hydraulic fluid from sealed containers
2-12
Installation Instructions
2.6 Filling Hydraulic Release System
continued
3. Connect the master cylinder assembly to the slave cylinder assembly if not already done. If filling or bleeding on the bench, as much as possible, arrange the hoses uncoiled, straight and running uphill. See Figure 2.6.1.
Figure 2.6.1 Hose Arrangements
GOOD HOSE ARRANGEMENT

6. Fill a syringe with approximately 35 cc of MIL-H-5606 fluid. Screw the end of the syringe into the screw hole on the slave cylinder to create a tight seal. See
Figure 2.6.4.
7. While observing the reservoir, slowly push on the syringe plunger to force fluid through the slave cylinder, hydraulic hose, and up to the master cylinder reservoir. There will be some resistance during filling—this is normal.
Injecting the fluid into the system too rapidly may cause the fluid to spray up and out of the master cylinder reservoir. Wear safety glasses when observing fluid reservoir while filling.

continued
8. Continue to force fluid into the master cylinder reservoir until the reservoir is approximately half full.
If bleeding an already filled system, you may need to draw fluid from the master cylinder reservoir during this step to prevent overflow.
9. Remove the syringe from the screw hole. Re-install the Stat-O-Seal (P/N 510-
496-00) and screw (P/N 510-493-00), see Figure 2.6.5.

10. Allow the system to rest for several minutes. This will allow any air to rise through the system.
11. Very slowly pull the release lever on the master cylinder and watch for bubbles. If bubbles are observed rising within the reservoir, continue to slowly cycle the lever until there are no more. Actuating the lever releases air trapped within the master cylinder.
Pull the lever very slowly! When the reservoir is not baffled and capped, a hard pull will cause fluid to erupt over the edge of the reservoir.

2.6 Filling Hydraulic Release System
continued
12. Check the system for air by actuating the lever firmly until it bottoms out.
Check the push rod position (see Figure 2.6.6). If the green area on the push rod is visible, proceed to step 13. If the green on the push rod is not visible with the lever completely pulled, the system has too much air in it and needs further bleeding. To do this, repeat steps 5 – 11.

Lever
Verify green ring on push rod is still visible
13. After the system is properly bled, verify that the reservoir is approximately half full of hydraulic fluid. Fluid should be visible above the baffle.
14. Re-install the baffle, and the reservoir lid.
15. Check the system for proper operation. Fully actuate the release lever. The hook must open and the lever must have a firm feel.
16. Disassemble and thoroughly clean the syringe with isopropyl alcohol. Allow it to dry. Not cleaning the syringe will render it unusable. Reassemble and store for next use.

Cargo Hook Operation Instructions
Operating Procedures
Prior to each flight involving external load operations perform the following:
1. Activate the electrical system and press the Cargo Hook release button to ensure the cargo hook electrical release is operating correctly. The Cargo
Hook should release. Reset the load beam.
The cargo hook release solenoid is intended to be energized only intermittently. Depressing the electrical release button continuously in excess of 20 seconds will cause the release solenoid to overheat, possibly causing permanent damage.
2. Activate the manual release lever on the collective. The mechanism should operate smoothly and the Cargo Hook should release. Reset the load beam.
3. Check the hydraulic release system for air by actuating the lever firmly until it bottoms out. Check the push rod position (see Figure 3.1). If some of the green ring on the push rod is visible, the system is adequately bled. If some of the green on the push rod is NOT visible with the lever completely pulled, the system has too much air in it and must be bled.

Cargo Hook Loading
The cargo hook can easily be loaded with one hand. A load is attached to the hook by pushing the ring upward against the upper portion of the load beam throat, as illustrated in Figure 3.2, until an internal latch engages the load beam and latches it in the closed position.
Figure 3.2 Cargo Hook Loading

Operation Instructions
Cargo Hook Rigging
Extreme care must be exercised when rigging a load to the Cargo Hook. Steel load rings are recommended to provide consistent release performance and resistance to fouling. The following illustration shows the recommended rigging, but is not intended to represent all rigging possibilities.
Some combinations of small primary rings and large secondary rings could cause fouling during release.
It is the responsibility of the operator to assure the cargo hook will function properly with each rigging.
Nylon Type Straps and Rope
Nylon type straps (or similar material) or rope must not be used directly on the cargo hook load beam. If nylon straps or rope must be used they should be first attached to a steel primary ring.
Verify that the ring will freely slide off the load beam when it is opened. Only the primary ring should be in contact with the cargo hook load beam.
