test set power switch to ON. Position the ALTITUDE x 1000 FEET control between 7 and 8. The altitude feet indication should increase to approximately 7750. You may have to vary the altitude trim control to obtain 7750 on the altitude feet indicator. Remove the A/AS arming key. The A/AS plunger should remain extended. 8. Use the pull tool to extend the plunger and install the arming key. Set the ALTITUDE x 1000 FEET control between 6 and 7. Vary the altitude trim control to obtain 6250 on the altitude feet indicator. The arming key should release with a pull of 6 to 16 pounds of force and the A/AS plunger should retract. 9. Again, you should use the pull tool to extend the plunger and reinstall the arming key. Position the altitude control to zero. After the altitude feet indication decreases to the set value, position the test set power switch to OFF. Rotate the static pressure vent and pitot pressure vent controls full counterclockwise. 10. Remove the manifold assembly from the A/AS and disconnect it from the test set. Disconnect the static pressure hose from the test set. Disconnect the power source and remove the test set. If the A/AS passes the functional check, you may install it on the seat. If the A/AS is faulty, you should forward it to depot-level maintenance for repair. CORROSION CONTROL The manufacturers of the Stencel ejection seat have stated that the seat is corrosion resistant. Therefore, on the special 40-day corrosion inspection, the SJU-8/A ejection seat has no inspection requirements. But we know that during shipboard operation, the seat will come in contact with salt spray, jet exhausts, stack gases, and various other debris. Although the seat is not addressed in the 40-day MRCs, it should be main- tained in accordance with the NA 01- lA-509 and local squadron instructions. The NA 01-l A-509 states that ejection seats should have a 7-day inspection performed while at sea and a 14-day inspection when ashore. LUBRICATING PROCEDURES You should ensure that oils, greases, pre- servatives, cleaning solutions, and solvents do not enter enclosed mechanisms, cartridge chambers, and ballistic hose and tube assemblies or come in contact with cartridges or initiators. You should cap all open ports during corrosion maintenance. All lubricants must be applied sparingly, and you must exercise care to protect nylon and cotton fabrics from contamination. Indiscriminant use of paint and preservatives that dry and build up with repeated or excessive application will often result in restricted movement of parts. This can easily render affected seats useless for ejection purposes. The following lubricants and procedures should be used on the Stencel ejection seat as stated in the NA 01- lA-509. 1. Lubricating oil, VV-L-800, should be applied to all parts that rotate, such as bell cranks, levers, pins, rollers, and similar components. 2. Grease, MIL-G-81322 or MIL-G-23827, should be applied to all parts that slide and should also be used as a corrosion preventive for all bright metal parts. 3. Apply MIL-C-85054 by brush or swab to all unpainted, nonmoving parts, such as nuts and bolts, that do not require lubrication. 4. Cleaning solvent and lubricants may be applied with brush or cloth providing adequate care is taken to prevent entry into closed mechanisms. 5. Surface contaminants such as dried lubricants, dirt, grit, or corrosion products can be removed from intricate bell cranks and levers by scrubbing with a small nylon bristle brush using P-D-680, Type II, cleaning solvent. Follow the cleaning solvent with a light coat of VV-L-800 oil to the entire component or assembly. EMERGENCY CLEANING The following emergency cleaning procedures should be used for cleaning ejection seats exposed to gross amounts of salt water or fire- extinguishing agents. The procedures described are normally used only to prevent further damage and will usually require further treatment at a higher level of maintenance. WARNING Disarm ejection seat mechanisms before cleaning. Only authorized personnel should disarm seats and perform cleaning operations. 1. Remove parachutes, drogue parachutes where applicable, and seat pans. These items 6-71
