Fault of the System Pressure Indication of the Blue Hydraulic System on the ECAM Lower DU

TASK 29-12-00-810-809-A
Fault of the System Pressure Indication of the Blue Hydraulic System on the ECAM Lower DU

1. Possible Causes

HYDR. PRESSURE TRANSMITTER [2065GN]

2. Job Set-up Information
A. Referenced Information

REFERENCE	DESIGNATION
AMM 29-12-00-710-001	Functional Check of Blue Electrical Pump Pressure by Reading ECAM Indication
AMM 29-32-11-000-002	Removal of the Hydraulic Pressure Transducer
AMM 29-32-11-400-002	Installation of the Hydraulic Pressure Transducer

3. Fault Confirmation
Subtask 29-12-00-710-061-A

A. Do the operational test of the electric pump of the Blue hydraulic system AMM 29-12-00-710-001.

4. Fault Isolation
Subtask 29-12-00-810-060-A

A. If, during the test, the operation of the flight controls is correct, but the HYD page on the ECAM lower DU shows for the Blue hydraulic system the subsequent condition:
the system pressure indication in amber (less than 1450 PSI),
the system pressure identification (BLUE) in white,
the system arrow in green.

replace the HYDR. PRESSURE TRANSMITTER [2065GN] AMM 29-32-11-000-002 and AMM 29-32-11-400-002.

Subtask 29-12-00-710-062-A

B. Do the test given in Para. 3
