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.
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: 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.

Subtask 27-21-00-860-072-A
C. Aircraft Maintenance Configuration
   (1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).

   (3) Do the IR alignment procedure for the ADIRU 3 only (Ref. AMM TASK 34-10-00-860-004).
NOTE: The ADIRUs 1 and 2 must be OFF. If the ADIRU 1 and 2 are ON, the test will not give satisfactory results.
   (4) On the overhead panel 23VU, make sure that:
  • the FAC1, ELAC1 and SEC1 pushbutton switches are pushed (the FAULT and OFF legends are off).
   (5) On the overhead panel 24VU, make sure that:
  • the FAC2, ELAC2, SEC2 and SEC3 pushbutton switches are pushed (the FAULT and OFF legends are off).
   (6) 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).
   (7) On the center pedestal, on the panel 110VU, make sure that the RUD TRIM indicator shows O.
   (8) 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).

A. Functional Test of the Rudder Mechanical Control
ACTION
RESULT
1.In the CAPT or F/O seat:
  • push the right pedal until it touches the mechanical (adjustable) stop.
The rudder moves smoothly 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,
  • the protractor that measures the rudder travel shows 25 deg. plus or minus 1 deg. (or X is between 643.5 mm (25.3347 in.) and 696 mm (27.4016 in.)).
2.Slowly release the right 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,
  • the protractor that measures the rudder travel shows 0 deg.. The maximum no-return value is 0.25 deg. (X = 6.75 mm (0.2657 in.)).
NOTE: The no-return value is the sum of the two no-return values of the travel of the rudder for a right turn and a left turn.
3.Push the left pedal until it touches the mechanical stop.
The rudder moves smoothly 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 to the left mark.
  • the protractor that measures the rudder travel shows 25 deg. plus or minus 1 deg. (or X is between 643.5 mm (25.3347 in.) and 696 mm (27.4016 in.)).
4.Slowly release the left 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,
  • the protractor that measures the rudder travel shows 0 deg.. The maximum no-return value is 0.25 deg. (X = 6.75 mm (0.2657 in.)).
