4. Procedure
Subtask 27-14-00-820-052-A

A. Adjustment of the Aileron when the Blue Outboard Servocontrol is Pressurized.

NOTE: If you see oscillations when the servocontrol is in the active mode, do a check of these oscillations (Ref. AMM TASK 27-14-00-200-001).

NOTE: To adjust an aileron, you must adjust the surface with one servocontrol active and then the other.

NOTE: At this time, the Blue servocontrol (33CE3, 33CE4) is in the active mode.

(1) Put a RULE in position on the trailing edge of the wing (inboard end of the wing) (see detail E).
(2) Use a RULER - GRADUATED to measure the position of the aileron in relation to the RULE .

NOTE: To optimize the theoretical loft line, the ailerons position must be as close as possible to the nominal values.
If the position of the aileron is not satisfactory, adjust the Blue servocontrol as follows:

(a) Cut and remove the lockwire from the bolts (3).
(b) Remove the bolts (3) and the lock plate (1).
(c) Set the control surface to zero with the adjusting nut (2).

NOTE: Always turn the adjusting nut (2) in the same direction to adjust the clearances and the hysteresis.

NOTE: If you turn the adjusting nut (2) clockwise while you look in the aircraft nose direction, the aileron trailing edge will move down.

(d) Install the lock plate (1) and the bolts (3).
(e) Safety the bolts (3) with the 14QFB1Wire-Locking Dia: 0.8 mm CRES Nickel Alloy -.
(3) Pressurize the Green hydraulic system (Ref. AMM TASK 29-10-00-863-001) or (Ref. AMM TASK 29-23-00-863-001)
(4) Depressurize the Blue hydraulic system (Ref. AMM TASK 29-10-00-864-003).

B. Adjustment of the Aileron when the Green Inboard Servocontrol is Pressurized.

NOTE: If you see oscillations when the servocontrol is in the active mode, do a check of these oscillations (Ref. AMM TASK 27-14-00-200-001).

NOTE: To adjust an aileron, you must adjust the surface with one servocontrol active and then the other.

NOTE: At this time, the Green servocontrol (33CE1, 33CE2) is in the active mode.

(1) Use a RULER - GRADUATED to measure the position of the aileron in relation to the RULE .

(a) Cut and remove the lockwire from the bolts (3).
(b) Remove the bolts (3) and the lock plate (1).
(c) Set the control surface to zero with the adjusting nut (2).

NOTE: Always turn the adjusting nut (2) in the same direction to adjust the clearances and the hysteresis.

NOTE: If you turn the adjusting nut (2) clockwise while you look in the aircraft nose direction, the aileron trailing edge will move down.

(d) Install the lock plate (1) and the bolts (3).
(e) Safety the bolts (3) with the lockwire.
(2) Remove the RULE from the trailing edge of the wing.
(3) On the panel 24VU, make sure that the OFF and FAULT legends of the FLT CTL/ELAC 2 pushbutton switch are off.

C. Aircraft Maintenance Configuration
(1) Remove the rigging pins and the warning notices from the side sticks.
(2) Do the EIS start procedure (Ref. AMM TASK 31-60-00-860-001).
(3) On the center pedestal, on the ECAM control panel, push the F/CTL key (on the lower ECAM D.U, the F/CTL page comes into into view).
(4) Pressurize the Blue hydraulic system (Ref. AMM TASK 29-10-00-863-003).
