3. Fault Confirmation
Subtask 29-11-00-710-060-A

A. Test

WARNING: MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROLS ARE CLEAR. MOVEMENT OF FLIGHT CONTROLS CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE.

(1) Pressurize the Green hydraulic system with the PTU AMM 29-23-00-863-001.
(2) Operate the rudder pedals.
(3) Make sure that the rudder operates.
(4) De-pressurize the Green hydraulic System AMM 29-23-00-864-001.

4. Fault Isolation
Subtask 29-11-00-810-059-A

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

replace the HYDR. PRESSURE TRANSMITTER [1065GN] AMM 29-32-11-000-001 and AMM 29-32-11-400-001.
