   (6) If clearance J1 is out of tolerance, adjust proximity switch 32WV (Ref. AMM TASK 52-71-12-400-002).
   (7) If clearance J3 is out of tolerance, adjust proximity switch 12MJ (Ref. AMM TASK 52-35-13-400-002).
   (8) If removed, install access panels 826AR, 826BR and 826CR (Ref. AMM TASK 52-32-33-400-001).
   (9) Install the inner access panel (1) with the washer (2) and the screw (3) on the door structure.
   (10) Make sure that the aft cargo-compartment door is correctly closed and locked when the test is completed (Ref. AMM TASK 52-30-00-860-002).

D. Test of the Drift Pin Mechanism
   (1) Open the aft cargo-compartment door until the drift pins are retracted from the door frame (Ref. AMM TASK 52-30-00-860-001).
   (2) Remove the aft cargo-compartment door-lining (Ref. AMM TASK 52-32-13-000-001).
   (3) Push the interlock lever of the interlock mechanism outboard to release the blockage from the locking mechanism.
   (4) Move the door handle down to the LOCKED position and push it in the recess of the door structure.
   (5) If necessary, adjust the position of the extended drift pins (Ref. AMM TASK 52-32-11-820-002).
   (6) Do the test that follows:
ACTION
RESULT
1.On the cargo door:
  • Measure distance F between the end of the extended drift pins and the edge members of the cargo door.
On the cargo door:
  • Distance F is between 34.7 mm (1.3661 in.) and 37.7 mm (1.4843 in.).
  • Pull the door handle away from the recess of the door structure and move it up to the UNLOCKED position.
  • The drift pins retract and the locking hooks are in the released position.
  • Examine the position of the retracted drift pins.
  • The retracted drift pins is behind the skin edge of the cargo door.
   (7) Install the door lining when the test is completed (Ref. AMM TASK 52-32-13-400-001) .
   (8) Make sure that the aft cargo-compartment is correctly closed and locked (Ref. AMM TASK 52-30-00-860-002).
