A. Adjustment of the Cockpit Door with the Self-Adhesive Foam Tape
(1) Use the FLASHLIGHT to do the inspection of the self-adhesive foam tape-strips (4).
(2) Make sure that the self-adhesive foam tape-strips (4), attached to the safety angle (3) and to the cockpit door wall-panel (1), are in the correct condition.
1 Remove the defective self-adhesive foam tape-strip (4) with the SCRAPER - NON METALLIC.
2 Clean the mating surfaces with Non Aqueous Cleaner-General - - (Material No.08BAA9) and the Textile-Lint free Cotton - (Material No.14SBA1) .
3 Apply the new AIPC 52-51-01-60-290 SELF-ADHESIVE FOAM TAPE-STRIP (4) or the new AIPC 52-51-01-33-260 TAPE (4) or the new AIPC 52-51-81-10-290 SELF-ADHESIVE FOAM TAPE-STRIP (4).
4 If no self-adhesive foam tape-strip (4) is available, make the door bumper with the Sealing Profile-- Silicone Foam - (Material No.14JAB1) to the correct width and thickness.
Subtask 52-51-00-865-154-A (1) Use the FLASHLIGHT to do the inspection of the self-adhesive foam tape-strips (4).
(2) Make sure that the self-adhesive foam tape-strips (4), attached to the safety angle (3) and to the cockpit door wall-panel (1), are in the correct condition.
NOTE: The safety angle (3) is installed on the lavatory wall (5).
NOTE: The self-adhesive foam tape-strips (4) are used as door bumpers at four locations: three on the safety angle (3) and one on the cockpit door wall-panel (1).
(a) If one self-adhesive foam tape-strip (4) is not in the correct condition or is missing, do the steps that follow:1 Remove the defective self-adhesive foam tape-strip (4) with the SCRAPER - NON METALLIC.
2 Clean the mating surfaces with Non Aqueous Cleaner-General - - (Material No.08BAA9) and the Textile-Lint free Cotton - (Material No.14SBA1) .
3 Apply the new AIPC 52-51-01-60-290 SELF-ADHESIVE FOAM TAPE-STRIP (4) or the new AIPC 52-51-01-33-260 TAPE (4) or the new AIPC 52-51-81-10-290 SELF-ADHESIVE FOAM TAPE-STRIP (4).
4 If no self-adhesive foam tape-strip (4) is available, make the door bumper with the Sealing Profile-- Silicone Foam - (Material No.14JAB1) to the correct width and thickness.
B. Remove the safety clip(s) and the tag(s) and close this(these) circuit breaker(s):

C. Operational Test of the Cockpit Door and the Latch Mechanism
(1) Do an operational test of the cockpit door (2) and the latch mechanism (Ref. AMM TASK 52-51-00-710-002).
(2) If the results of the test are unsatisfactory or you cannot install the self-adhesive foam tape-strips (4) as in step 4.A:
5. Close-up(1) Do an operational test of the cockpit door (2) and the latch mechanism (Ref. AMM TASK 52-51-00-710-002).
(2) If the results of the test are unsatisfactory or you cannot install the self-adhesive foam tape-strips (4) as in step 4.A:
- Do the adjustment procedure of the cockpit door (2), the electrical release strikes and the latch mechanisms (Ref. AMM TASK 52-51-00-820-001).
