C. Aircraft Maintenance Configuration
WARNING : MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROL SURFACES
_______ ARE CLEAR BEFORE YOU PRESSURIZE/DEPRESSURIZE A HYDRAULIC SYSTEM.
(1)
Energize the aircraft electrical circuits. (Ref. TASK 24-41-00-861-002)
(2)
Pressurize the Blue hydraulic system with the electric pump. (Ref. TASK 29-10-00-863-003)
(3)
Put the rudder pedals in the neutral position.
(4)
On the center pedestal, on the panel 110VU, make sure that the RUD TRIM indicator shows 0.
(5)
Depressurize the Blue hydraulic system and put it in the maintenance configuration (Ref. TASK 29-00-00-864-001).
(6)
Make sure that the Green and Yellow hydraulic systems are depressurized and put them in the maintenance configuration (Ref. TASK 29-00-00-864-001).
(7)
On the overhead panel 23VU, release the FLT CTL/FAC 1 pushbutton switch. The OFF legend comes on.
(8)
On the overhead panel 24VU, release the FLT CTL/FAC 2 pushbutton switch. The OFF legend comes on.
(9)
Put the warning notices in the cockpit to tell persons not to operate the flight controls.
(10)
De-energize the aircraft electrical circuits. (Ref. TASK 24-41-00-862-002)
(11)
Put the warning notices in position to tell persons not to operate the hydraulic systems:
-in the cockpit on the hydraulic section 40VU of the overhead panel,
- on the ground service panels of the Green, Yellow and Blue hydraulic systems.
(12) Put the PIN - RIGGING (98D27207545000) (20) in the bellcrank assembly
(2) of the travel limitation unit (3).
