should be returned to local work centers for cleaning or replacement. 2. Remove ejection seats according to the applicable MIM. 3. Remove the CADs, rockets, and inertia reels from the seats. Cap all gas lines and ports. Then, wipe down these components with fresh water. 4. Rinse the seat thoroughly with fresh water. Continue washing while directing the water into crevices and close fitting parts until the contaminants are removed. 5. Blow as much water as possible from equipment with low pressure, clean, dry air. 6. Dry excess water deposits with a clean cloth, clean paper towels, or remnant cloths. 7. Apply the water displacing preservative MIL-C-81309, Type II, by spray or brush to critical metal surfaces and to recess areas that may not be completely dry. Water displacing pre- servative protects equipment during necessary inspection or inquiry, and during transfer to the repair custodian. 8. Wash all survival gear and pilot safety equipment with fresh water and dry thoroughly. You should refer to NAVAIR 13-l-6-X for detailed preservation procedures. Lubricate and control corrosion in accordance with maintenance requirements cards. 9. You should comply with all special inspection requirements before reinstallation. Reassemble ejection seats in accordance with the MIMs. 10. If necessary, send the ejection seat to the next higher level of maintenance. 11. Aircraft-mounted escape system com- ponents (mechanically activated CADs) should be wiped with fresh water, a cloth, and dried. If external contamination is suspected, these components should be removed and replaced. CORROSION CONTROL The existing MIMs and MRCs for most ejection seat systems do not provide sufficient or explicit instruction for corrosion control and lubrication. The Aircraft Weapons System Cleaning and Corrosion Control Manual, NA 01-lA-509, and COMNAVAIRPAC/COM- NAVAIRLANT INSTRUCTION 4750.2 (series) contain more information on corrosion control. These publications should be on your required reading list. The Aviation Maintenance Ratings (AMR) Fundamentals, NAVEDTRA 10342-3, and Aviation Maintenance Ratings (AMR) Supervisor, NAVEDTRA 10343-A1, also contain information regarding corrosion control. If needed, commands may develop local MRCs or local maintenance instructions to help eliminate corrosion of ejection seats. The following general information pertains to most ejection seats. Steps must be taken to prevent corrosion before it occurs. Correct procedures for repair of components and systems after corrosion has been treated must be used to ensure that corrosion does not return. The performance of the 210- and 364-day inspections, the 7-day inspections while at sea, and the 14-day inspections while ashore should be conducted according to the applicable MIMs and MRCs. Preventive maintenance on seat components, including procedures for cleaning and lubrication, is discussed in the following paragraphs. Seat Structure and Components Command philosophy varies regarding the painted parts of a seat structure. Some squadrons strip and paint at each 210- and 364-day inspection. Some leave the original anodized finish unpainted. Some touch-up chipped paint. Some do nothing. Each of these philosophies has some merit depending upon local conditions. The seat bucket and beam structure should be wiped with VV-L-800 general-purpose oil. You should allow the oil to soak into crevices, around rivets, and then wipe dry. Clean metal components with P-D-680, Type II, dry-cleaning solvent, and then inspect them for surface damage and corrosion. Do not attempt to remove light corrosion or discoloration of the cadmium-plated parts. Parts showing rust or pitting of the base metal or more than one area of plating loss should be replaced. Remove light corrosion, except for cadmium plated parts, by using a fine Scotchbrite abrasive mat or 500/600 aluminum oxide abrasive cloth. Lubricate moving parts, such as springs, linkage, and pivot areas, with MIL-G-81322 general-purpose grease. Lubricate firing pins and rollers with VV-L-800 oil. When using VV-L-800 oil, you should apply it with a clean, lint-free cloth such as MIL- C-85043. Indiscriminate use of paint, preservatives, or other materials that dry and buildup following application can prevent or restrict proper motion of movable parts. These materials must only be used where specified on nonmoving parts. Paint touch-ups of seats installed on the aircraft should be done with a brush. 6-72
