Subtask 27-26-51-860-057-A
A. Aircraft Maintenance Configuration
WARNING : OBEY THE HYDRAULIC SAFETY PROCEDURES.
_______
(1)
Obey the hydraulic safety procedures (Ref. TASK 29-00-00-910-002).
(2)
Make sure that the adjustable access platform is in position at zone
325.
R (3) Make sure that the access panel 325BL (for the pressure switch on R 3CC1) or 325BR (for the pressure switch on 3CC2) is open (Ref. TASK 55-33-13-010-002).
(4)
Make sure that the rudder pedals are in the neutral position.
(5)
Make sure that the RUD TRIM indicator on the center pedestal, on the panel 110VU shows 0.
(6)
Make sure that the warning notices are in position in the cockpit to tell persons not to operate the flight controls.
(7)
Make sure that the hydraulic systems are depressurized and put them in the maintenance configuration. (Ref. TASK 29-00-00-864-001).
(8)
Make sure that the reservoirs of the Green and Yellow hydraulic systems are depressurized (Ref. TASK 29-14-00-614-001).
(9)
Make sure that the aircraft electrical circuits are de-energized (Ref. TASK 24-41-00-862-002).
(10) Make sure that the warning notices are in position to tell persons not to pressurize the Green, the Yellow and the Blue 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.
(11)
Make sure that the PIN - RIGGING 98D27207516330, part of the RIGGING PIN SET (98D27207516000), or the PIN - RIGGING (98D27207549000) is in position in the yaw damper bellcrank.
(12)
Make sure that the container is in position below the yaw damper to collect unwanted fluid.
