(1)
Put the safety barriers in position.
(2)
Make sure that the ground safety locks are installed on the landing gear (Ref. 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 R - put a warning notice in position to tell persons not to operate the R Landing Gear and the NLG doors.

B. Aircraft Maintenance Configuration
(1)
Make sure that the Green hydraulic system is depressurized. (Ref. TASK 29-10-00-864-001).
(2)
Disconnect the isolation coupling of the PTU (Ref. TASK 29-23-00-860-001).
(3)
If the electrical power is not necessary for other maintenance tasks, de-energize the aircraft electrical circuits (Ref. TASK 24-41-00-862-002). Then, it is not necessary to open the LGCIU circuit breakers.
(4)
If the electrical power is necessary, do the precautions for flight configuration (Ref. TASK 32-00-00-860-001) before you open the LGCIU circuit breakers.

D. Get Access
(1)
Open the NLG doors (Ref. TASK 32-22-00-010-001).
(2)
Make sure that a SAFETY PIN - NLG DOOR (98D32203502000) is installed in each NLG door (Ref. TASK 32-00-00-481-002).
