NOTE : If you see oscillations when the servocontrol is in the active
____ mode, do a check of these oscillations (Ref. 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 ruler in position on the trailing edge of the wing (inboard end of the wing) (see detail E).
(2)
Use a graduated ruler to measure the position of the aileron in relation to the ruler.
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.
(d)
Install the lock plate (1) and the bolts (3).
(e)
Safety the bolts (3) with the lockwire.
(3) Pressurize the Green hydraulic system (Ref. TASK 29-23-00-863-001).
(4) Depressurize the Blue hydraulic system (Ref. TASK 29-10-00-864-003). Subtask 27-14-00-820-053
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. 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 graduated ruler to measure the position of the aileron in relation to the ruler.
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 Green 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.

(d)
Install the lock plate (1) and the bolts (3).
(e)
Safety the bolts (3) with the lockwire.
(2)
Remove the ruler from the trailing edge of the wing.
(3)
Make sure that the 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. 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. TASK 29-10-00-863-003).
(5)
On the panel 23 VU, release the FLT CTL/ELAC1 pushbutton switch (on this pushbutton switch, the OFF legend comes on).
