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
