52.3.3.1
Perform emergency ejection check on
crew doors (paragraph 52.2.2.3). Inspect as
follows:
52.3.3.1.1
Check for contamination and
corrosion. If any exists proceed to step 52.3.3.2.
52.3.3.1.2 Check for damaged seal. If damage
exists, refer to step 52.3.3.5.
52.3.3.1.3 Check for damaged locking pin hole
damage. If damage exists, refer to step 52.3.3.6.
52.3.3.2
Remove contamination as follows:
52.3.3.2.1 Scrub affected area using clean, lint
free cloths and cleaning compound (C-3l8) until
free of contaminant.
52.3.3.2.2 Thoroughly rinse with water.
52.3.3.2.3 Dry with clean, lint-free cloths or
filtered, compressed air.
52.3.3.2.4 Inspect surface for corrosion and/or
surface damage or seal deterioration. If none
exists, return to service. If any of these conditions
exists, proceed to next step.
52.3.3.3
Remove minor corrosion and treat
area as follows:
NOTE
Corrosion pits shall be no larger than 0.060 in.
(1.524 mm) in major surface dimension and
0.020 in. (0.51 mm) in depth. Frequency shall
not exceed fourteen (14) per sq. in. Corrosion
pits exceeding limits shall be reworked in
accordance with step 52.3.3.4.
52.3.3.3.1 Clean
surface (step 52.3.3.2)
52.3.3.3.2 Brush corrosion pits with cleaner (C-
344). Allow solution to remain on surface one to
three minutes.
52.3.3.3.3 Thoroughly
rinse surface.
52.3.3.3.4 Dry with clean, lint-free cloths or
filtered, compressed air.
52.3.3.3.5 Apply chemical film material (C-100)
liberally to surface with natural fiber brush (do
not use nylon). Allow to remain on surface 30
seconds to one minute.
52.3.3.3.6 Thoroughly rinse with water. The
surface should be free from any powdery or
loose film areas, scratches, flaws, and deflects.
The rinse water will not collect into droplets
within 25 seconds if surface is satisfactory. If
surface is not satisfactory, repeat steps
52.3.3.3.4, 52.3.3.3.5, and 52.3.3.3.6.
52.3.3.3.7 Dry thoroughly with clean, dry cloths
or with filtered, compressed air.
52.3.3.3.8 If no seal is to be applied to surface,
apply epoxy/zinc coating (C-208). If seal is
required, mask area where seal is to be
attached and apply epoxy/zinc coating (C-208)
to exposed surface.
52.3.3.4
Rework corrosion pits which exceed
limitations outlined in step 52.3.3.3 as follows:
CAUTION
