A. Get Access

4. Procedure
Subtask 52-30-00-220-050-A ** ON A/C NOT FOR ALL

A. Inspection of the Door Seal
(1) Do a visual inspection of the door seal for:

signs of chafe marks
minor cuts and small punctures
large areas of damage
the correct positions of the inflation holes.

NOTE: The inflation holes are in the correct positions if they are on the inner side of the cargo compartment door.
If the inflation holes are not in the correct location, it is not possible to inflate the door seal during the flight.
This causes the cabin pressure to decrease and can result in a disruption of the flight.

(2) If necessary, repair the door seal:

for the FWD cargo-compartment door (Ref. AMM TASK 52-31-18-300-001)
for the AFT cargo-compartment door (Ref. AMM TASK 52-32-18-300-001).
