D. Test of the Landing Gear Control-Lever
(1) Do the BITE test of the landing-gear control interface-unit (Ref. AMM TASK 32-69-00-740-001).

NOTE: As an alternative procedure, you can do this test without the centralized fault display-system (Ref. AMM TASK 32-31-00-720-002).

(2) Do a check of the mechanical integrity of the landing gear control-lever as follows:
(a) Open, safety and tag this(these) circuit breaker(s):

1GA
2GA
52GA
58GA
59GA.

(b) Use the TIE WRAP(S) to install 98F32304000000 TARGET-FALSE on weight-on-wheels proximity sensors 20GA, 21GA, 22GA, 23GA, 24GA and 25GA.
(c) Remove the safety clip(s) and the tag(s) and close this(these) circuit breaker(s):

1GA
2GA
52GA
58GA
59GA.

(d) In the cockpit, set the landing gear control-lever to UP.
(e) Set the landing gear control-lever to DOWN.
(f) Do the steps (d) and (e) again.
(g) Open, safety and tag this(these) circuit breaker(s):

1GA
2GA
52GA
58GA
59GA.

(h) Remove and discard the TIE WRAP(S).
(i) Remove the 98F32304000000 TARGET-FALSE from weight-on-wheels proximity sensors 20GA, 21GA, 22GA, 23GA, 24GA, and 25GA.
(j) Remove the safety clip(s) and the tag(s) and close this(these) circuit breaker(s):

1GA
2GA
52GA
58GA
59GA.

(k) Make sure that you cannot set the landing gear control-lever to UP.

5. Close-up
Subtask 32-31-11-410-050-A

A. Close access.
(1) Make sure that the work area is clean and clear of tool(s) and other items
(2) Remove the safety devices from the landing gear doors (Ref. AMM TASK 32-00-00-081-002).
(3) Close the MLG doors and the NLG doors (Ref. AMM TASK 32-12-00-410-001) (Ref. AMM TASK 32-22-00-410-001).
