Subtask 29-12-00-860-050
B. Aircraft Maintenance Configuration
(1)
Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).
(2)
Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. TASK 31-60-00-860-001).
(3)
On the ECAM control panel on the center pedestal, push the HYD pushbutton. Make sure that the ECAM lower Display Unit (DU) shows the HYD page.
(4)
On the panel 24VU, make sure that the ELAC 2 pushbutton switch (P/BSW) is set to ON (OFF and FAULT lights off).
(5)
On the panel 23VU, make sure that the ELAC 1 and SEC 1 P/BSW are set to ON (OFF and FAULT lights off).
(6)
Make sure that the ECAM does not show any of these conditions:
-
Low air pressure in the Blue reservoir,
-
Low fluid level in the Blue reservoir.
(7)
If necessary, pressurize the reservoir (Ref. TASK 29-14-00-614-002).
(8)
If necessary. add fluid to the reservoir (Ref. TASK 12-12-29-611-001).
(9)
On the panel 40VU, make sure that the BLUE ELEC PUMP P/BSW is set to AUTO (OFF and FAULT lights off).
4. Procedure
_________ Subtask 29-12-00-710-050
A. Do this test: WARNING : MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROL SURFACES
_______ ARE CLEAR BEFORE YOU PRESSURIZE/DEPRESSURIZE A HYDRAULIC SYSTEM.
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.
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the panel 50VU:
-push the BLUE PUMP OVRD P/BSW.
2.
Slowly operate the ailerons, the elevators and the rudder.
3.
Stop the operation of the control surfaces.
4.
On the panel 40VU:
-push the BLUE ELEC PUMP P/BSW.
On the panel 50VU:
-the ON light of the BLUE PUMP OVRD P/BSW comes on.
The electric pump of the Blue hydraulic system starts.
On the ECAM lower DU:
-
the pressure in the Blue hydraulic system must be between 2800 and 3200 psi.
On the ECAM lower DU:
-
the pressure in the Blue hydraulic system must be not less than 2200 psi (with the control surfaces in operation).
On the ECAM lower DU:
-
the pressure in the Blue hydraulic system must increase to between 2800 and 3200 psi.
On the panel 40VU:
-
the OFF light of the BLUE ELEC PUMP P/BSW comes on.
On the panel 50VU:
-The ON light of the BLUE PUMP OVRD P/BSW goes off.
The electric pump of the Blue hydraulic system stops.
5. Close-up
________ Subtask 29-12-00-860-051
A. Put the aircraft back to its initial configuration.
(1)
On the panel 40VU, push and release the BLUE ELEC PUMP P/BSW. Make sure that the OFF and FAULT lights are not on.
(2)
Do the EIS stop procedure
(Ref. TASK 31-60-00-860-002).
(3)
