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 and the bleed pressure regulator valve 4001HA
-
sense line between the HP bleed valve (4000HA), the bleed pressure
regulator va ve (4001HA) and the soleno d (11HA2) on engine 2.

_______________
R **ON A/C 001-049, 051-099, 101-105, 201-228, 301-302,
A. If the fault symptom is identified by the maintenance message: 361151 HP BLEED-V 4000HA2 OR SENSE LINE
-do the functional test of the bleed transferred pressure transducer (7HA2) (Ref. AMM TASK 36-11-15-720-001).
(1)
If the test is not OK:
-replace the XDCR-BLEED TRANSFER PRESS, ENG 2 (7HA2) (Ref. AMM TASK 36-11-15-000-001) (Ref. AMM TASK 36-11-15-400-001)
-refer to Para. 4.B.
(2)
If the test is OK:
-disconnect the sense line from the HP bleed valve of the engine 2
-put a cap 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 (Ref. AMM TASK 36-11-51-720-001).
(a)
If the test is not OK:
-replace the VALVE-HP BLEED (4000HA) of the engine 2 (Ref. AMM TASK 36-11-51-000-040) (Ref. AMM TASK 36-11-51-400-040)
-refer to Para. 4.B.
(b)
If the test is OK:
-replace the sense line between the HP bleed valve and the bleed pressure regulator valve 4001HA of the engine 2
-refer to Para. 4.B.
**ON A/C 151-199,
A. If the fault symptom is identified by the maintenance message: 361151 HP BLEED-V 4000HA2 OR SENSE LINE
