(10) If necessary, add fluid to the reservoir(s) (Ref. TASK 12-12-29-611-001) or (Ref. TASK 12-12-29-611-002).
4. Procedure
_________
Subtask 29-32-00-710-052
A. Do this test:
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1.
Pressurize the Yellow hydraulic system from a ground supply, through the PTU or with the electric pump (Ref. TASK 29-10-00-863-002) or (Ref. TASK 29-23-00-863-002) or (Ref. TASK 29-24-00-863-001).
2.
On the overhead panel 50VU:
-lift the guard and push and release the HYD /LEAK MEASUREMENT VALVES/Y P/BSW.
3. Depressurize the Yellow hydraulic system (Ref. TASK 29-10-00-864-002) or (Ref. TASK 29-23-00-864-001) or (Ref. TASK 29-24-00-864-001).
On the ECAM lower DU:
-
the Yellow system pressure is 3000psi approximately.
-
the system name is white.
-
the flow arrow is green.
On the overhead panel 50VU:
-
the OFF light of the HYD /LEAKMEASUREMENT VALVES/Y P/BSW comes on.
On the ECAM lower DU:
-
the color of the system name changes from white to amber.
-
the color of the flow arrow changes from green to amber.
On the ECAM lower DU:
-
the digital display of the systempressure shows the reduction of thepressure in the Yellow system.
-
the color of the digital display of the system pressure changes from green to amber at approximately 1450 psi.
5. Close-up
________ Subtask 29-32-00-860-054
A. Put the aircraft back to the serviceable condition.
(1)
On the overhead panel 50VU, push the HYD /LEAK MEASUREMENT VALVES/Y P/BSW. Make sure that the OFF light goes out.
(2)
If the PTU is isolated, connect the PTU isolation coupling (Ref. TASK 29-23-00-860-002).
(3)
Do the EIS stop procedure
(Ref. TASK 31-60-00-860-002).
(4)
De-energize the aircraft electrical circuits (Ref. TASK 24-41-00-862-002).
