3. Job Set-up
Subtask 32-31-00-941-050-A

A. Safety Precautions
(1) Put the SAFETY BARRIER(S) in position.
(2) Make sure that the ground safety locks are in position (Ref. AMM TASK 32-00-00-481-001).
(3) On the panel 400VU:

make sure that the landing-gear control-lever 6GA is in the DOWN position
put a WARNING NOTICE(S) in position to tell persons not to operate the landing gear.

(4) Put the WARNING NOTICE(S) in position to tell persons not to pressurize the Yellow and Green hydraulic systems.

Subtask 32-31-00-860-057-A

B. Aircraft Maintenance Configuration
(1) Make sure that the Yellow and the Green hydraulic systems are de-pressurized (Ref. AMM TASK 29-10-00-864-001) and (Ref. AMM TASK 29-10-00-864-002).
(2) Make sure that the applicable hydraulic reservoirs have been depressurized (Ref. AMM TASK 29-14-00-614-001).

Subtask 32-31-00-861-050-A

C. Energize the Electrical Circuits
(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).

4. Procedure
Subtask 32-31-00-710-050-A

A. Operational Check of the Retraction Inhibition Baulk

ACTION	RESULT
On panel 400VU:
Pull the landing-gear control-lever 6GA to you, then try to lift it to the UP position.	The operation of the retraction inhibition baulk will prevent an UP selection.
