HP Bleed Valve Locked in the Not Fully Open Position on the Engine 2

TASK 36-11-00-810-840-A
HP Bleed Valve Locked in the Not Fully Open Position on the Engine 2

WARNING: MAKE SURE THAT THE PNEUMATIC SYSTEM IS DEPRESSURIZED BEFORE YOU START WORK ON THE PNEUMATIC SYSTEM.
WARNING: MAKE SURE THAT PERSONS DO NOT START THE ENGINES DURING THIS PROCEDURE; IT IS DANGEROUS TO WORK ON OR GO NEAR AN ENGINE WHEN IT OPERATES.
1. Possible Causes
  • XDCR-BLEED TRANSFER PRESS, ENG 2 [7HA2]
  • VALVE-HP BLEED [4000HA]
  • sense line between the HP bleed valve (4000HA), the bleed-pressure regulator valve (4001HA) and the solenoid (11HA2)
  • sense line between the HP bleed valve (4000HA), the bleed pressure regulator valve (4001HA) and the solenoid (11HA2)

A. Not Applicable
4. Fault Isolation
Subtask 36-11-00-810-090-A ** ON A/C NOT FOR ALL
A. If the fault symptom is identified by the maintenance message:
361151
HP BLEED-V
4000HA2
OR SENSE LINE
   (1) If the test is not OK:
   (2) If the test is OK:
  • disconnect the sense line from the HP bleed valve of the engine 2
  • put a CAP - BLANKING on the pressure port of the sense line of the HP bleed valve
  • do a functional test of the opening of the engine 2 HP bleed valve AMM 36-11-51-720-001.
     (a) If the test is not OK:
     (b) If the test is OK:
  • replace the sense line between the HP bleed valve (4000HA), the bleed-pressure regulator valve (4001HA) and the solenoid (11HA2) of the engine 2 AMM 36-11-49-000-029 and AMM 36-11-49-400-029.
  • refer to Para. 4.B.
