should be returned to local work centers for
cleaning or replacement.
2. Remove ejection seats according to the
3. Remove the CADs, rockets, and inertia
reels from the seats. Cap all gas lines and ports.
Then, wipe down these components with fresh
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
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
9. You should comply with all special
inspection requirements before reinstallation.
Reassemble ejection seats in accordance with the
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.
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-
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.
