HYDRAULIC SYSTEMS A, B, AND STANDBY - MAINTENANCE PRACTICES
___________________________________________________________
1. General_______
A. When it is necessary to open a hydraulic line, you must release the pressure from the reservoir for the applicable hydraulic system (AMM 29-09-00/201).
B. If hydraulic fluid gets on the airplane, then refer to 12-40-00/201 to clean it up.
TASK 29-15-00-862-001
2. Pressurize the A, B, or Standby Hydraulic System________________________________________________
A. General
(1)
Hydraulic systems A and B are almost the same, thus the same procedure is used for the two systems. The standby hydraulic system has a different procedure.
(2)
If you pressurize the A hydraulic system, these parts will get hydraulic power:
(a)
The ground spoilers (0, 1, 4, 5, 8, 9)
(b)
Through the alternate (brake) source selector valve (alternate source) 1) Deleted. 2) The alternate brakes
(c)
The left thrust reverser (primary source)
(d)
The landing gear transfer valve (primary source landing gear operation)
(e)
Through the system A flight control module 1) The flight spoilers 3, 6 2) The lower aileron power control unit 3) The right auto-pilot actuator 4) The rudder 5) The left elevator power control unit 6) The lower auto-pilot actuator 7) The left elevator feel
(3)
If you pressurize the B hydraulic system, these parts will get hydraulic power:
(a)
The leading edge flaps and slats
(b)
The trailing edge flaps
(c)
The primary brakes
1) Deleted.
(d)
The right thrust reverser (primary source)
(e)
The landing gear transfer valve (alternate source landing gear operation)
(f)
Through the system B flight control module 1) The flight spoilers 2, 7
