4. Fault Isolation
_______________
A. Procedure
(1) If the uplock stays shut, replace the applicable Uplock Assembly:
- for the NLG Uplock Assembly (2530GM) (Ref. AMM TASK 32-31-21-000-001) and (Ref. AMM TASK 32-31-21-400-001).
- for the MLG Uplock Assembly (2509GM) or (2510GM) (Ref. AMM TASK 32-31-44-000-001) and (Ref. AMM TASK 32-31-44-400-001).

A. Test
(1) Test not applicable. NOTE : If there is a loss of gas or oil from the NLG shock absorber,
____ there can be an effect on the aircraft steering or loading/unloading properties.
4. Fault Isolation
_______________
**ON A/C 001-049, 051-099, 101-149, 201-299,
A. Procedure NOTE : If a leakage from the NLG shock absorber has occurred, one return
____ flight is permitted for repair to be completed, if:

(1) Use the data in the tables that follow to do a check of the NLG shock absorber extension (dimension H):
(a) At the NLG measure and record the dimension H.
(Ref. Fig. 202/TASK 32-31-00-991-016)
(b) Compare the recorded dimension with the applicable dimension given in the tables that follow:
- if the shock absorber extension is not correct, do the next step.
NOTE : The recorded dimension H must be equal to, or 15 mm
____ (0.5905 in.) less than, the dimension given in the table.
NOTE : It is recommended that the complete procedure is done
____ again with a different aircraft weight and/or C of G configuration. To find the weight and C of G of the aircraft, go to (Ref. AMM TASK 08-10-00-200-001)
(2) Do a replenishment of the NLG shock absorber (Ref. AMM TASK 12-12-32-611-001).
