Operational Test of the Rudder Hydraulic Actuation

TASK 27-24-00-710-001-A
Operational Test of the Rudder Hydraulic Actuation

WARNING: MAKE SURE THAT THE GROUND SAFETY-LOCKS ARE IN POSITION ON THE LANDING GEAR. THIS WILL PREVENT UNWANTED MOVEMENT OF THE LANDING GEAR, AND THUS POSSIBLE INJURY TO PERSONS AND DAMAGE TO THE AIRCRAFT AND/OR EQUIPMENT.

WARNING: MAKE SURE THAT THE CONTROLS AGREE WITH THE POSITION OF THE ITEMS THEY OPERATE BEFORE YOU PRESSURIZE A HYDRAULIC SYSTEM. UNWANTED MOVEMENT OF HYDRAULICALLY OPERATED ITEMS CAN CAUSE SERIOUS INJURY AND/OR DAMAGE.

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

WARNING: PUT THE SAFETY DEVICES AND THE WARNING NOTICES IN POSITION BEFORE YOU START A TASK ON OR NEAR:

THE FLIGHT CONTROLS
THE FLIGHT CONTROL SURFACES
THE LANDING GEAR AND THE RELATED DOORS
COMPONENTS THAT MOVE.

MOVEMENT OF COMPONENTS CAN KILL OR CAUSE INJURY TO PERSONS AND/OR CAN CAUSE DAMAGE TO THE EQUIPMENT.

3. Job Set-up
Subtask 27-24-00-860-055-A

A. Aircraft Maintenance Configuration
(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(2) Pressurize the aircraft hydraulic systems
(Ref. AMM TASK 29-23-00-863-001) (Ref. AMM TASK 29-24-00-863-001) (Ref. AMM TASK 29-10-00-863-003).
(3) On the center pedestal, on panel 110VU, make sure that the RUD TRIM indicator shows 0.
(4) Do the EIS start procedure (Ref. AMM TASK 31-60-00-860-001).
(5) On the center pedestal, on the ECAM control panel, push the F/CTL key (on the lower ECAM display unit, the F/CTL page comes into view).

4. Procedure
Subtask 27-24-00-710-050-A

A. Do this test:

ACTION	RESULT
1.On the CAPT or F/O side: push the right rudder pedal until it touches the mechanical stop.	The rudder moves to the right. On the lower ECAM display unit, on the F/CTL page: the RUD/G, B, Y symbols are green, the pointer of the RUD indicator moves smoothly to the right mark.
2.Slowly release the right rudder pedal and then push the left rudder pedal until it touches the mechanical stop.	The rudder moves from the right to the left. On the lower ECAM display unit, on the F/CTL page: the RUD/G, B, Y symbols are green, the pointer of the RUD indicator moves smoothly from the right mark to the left mark smoothly.
3.Slowly release the left rudder pedal.	The rudder moves to the neutral position. On the lower ECAM display unit, on the F/CTL page: the RUD/G, B, Y symbols are green, the pointer of the RUD indicator moves to the neutral position.

5. Close-up
Subtask 27-24-00-860-056-A

A. Put the aircraft back to its initial configuration.
(1) Depressurize the aircraft hydraulic systems (Ref. AMM TASK 29-23-00-864-001) (Ref. AMM TASK 29-24-00-864-001) (Ref. AMM TASK 29-10-00-864-003).
(2) Do the EIS stop procedure (Ref. AMM TASK 31-60-00-860-002).
(3) De-energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-862-002).
(4) Make sure that the work area is clean and clear of tools and other items.
