 Do this test:
 NOTE : If necessary, adjust the clearance of

____
 -
the proximity switches 28WV (Ref. TASK 52-71-12-400-001),

 -
the proximity switches 30WV (Ref. TASK 52-71-12-400-002),

1. On the proximity switches 28WV: On the proximity switches 28WV:
 -measure the clearance between  - the clearance must be between 1.6 mm the target on the door handle (0.0629 in.) and 2.0 mm (0.0787 in.). and the sensor on the door structure.
 2. On the proximity switches 30WV: On the proximity switches 30WV:

 -------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
-measure the clearance between  - the clearance must be between 1.5 mm the target on the target lever (0.0590 in.) and 2.0 mm (0.0787 in.). (part of the switch mechanism) and the sensor on the cargo door sill.
 3. On the cargo door:  On the cargo door:
 -pull the door handle away from  - the cargo door is in the unlocked the recess and move it fully up condition. to the UNLOCKED position.
 4. On the proximity switches 5MJ: On the proximity switches 5MJ:
 -measure the clearance between  - the clearance must be between 1.6 mm the target on the latching (0.0629 in.) and 2.0 mm (0.0787 in.). shaft and the sensor on the structure.
 (4)
 Install the access panel 825AR.

 (5)
 Make sure that the cargo door is correctly closed and locked (Ref. TASK 52-30-00-860-002) when the test is completed.

 (Ref. Fig. 501/TASK 52-31-00-991-001-A)

 (1)
 Open the cargo door (Ref. TASK 52-30-00-860-001) until the drift pins are free from the door frame.

 (2)
 Remove the door lining from the cargo door (Ref. TASK 52-31-13-000-001).

 (3)
 Push the lever of the interlock mechanism outboard to release the blockage of the locking mechanism.

 (4)
 Move the door handle fully down to the LOCKED position and push it in the recess of the door structure.

 (5) Do this test: NOTE : If necessary, adjust the position of the extended and
____ retracted drift pins (Ref. TASK 52-31-11-820-002).
 -------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the cargo door:
-measure the distance "U" between the end of the extended drift pins and the edge members of the cargo door.
 -pull the door handle away from the door structure and up to the fully UNLOCKED position.
-examine the position of the retracted drift pins.
On the cargo door:
-
the distance "U" must be between 34.7mm (1.3661 in.) and 37.7 mm (1.4842in.).

-
the drift pins retract and thelatching hooks are in the releasedposition.

-
the retracted drift pins must bebehind the skin edge of the cargo door.

 (6) Install the door lining (Ref. TASK 52-31-13-400-001) when the test is
 completed.
 (7) Make sure that the cargo door is correctly closed and locked
 (Ref. TASK 52-30-00-860-002).
