7_ Install the LOCKING TOOL - FLAP/SLAT CONTROL LEVER
(98D27803000000).
8_ If necessary, adjust the servocontrol (Ref Para. B).
(2) For the spoilers 2, 3 and 4: X=-2 +0.5 -0.5 mm (-0.0787 +0.0196 -0.0196 in.)
NOTE : You must do this measurement at the closest point (point where
____ the gap between the spoiler and the flap is the smallest).
(a) Adjustment of the interference X without tool. 1 Adjust the servocontrol (Ref. Para. B) in order to measure:
_ X =2 +0.5 -0.5 mm (0.0787 +0.0196 -0.0196 in.).
2 Adjust the servocontrol again (Ref Para. B) by half a turn
_ clockwise in order to get the negative clearance.
(b) Adjustment of the interference X with the SPOILER POSITION CHECK TOOL (98D27603000001).
1 Install the SPOILER POSITION CHECK TOOL (98D27603000001) as
_ follows: - on the upper surface of the wing - on the trailing edge of the spoiler
-at the closest point of the spoiler. 2 Read the position of the spoiler.
_ 3 Remove the LOCKING TOOL - FLAP/SLAT CONTROL LEVER
_ (98D27803000000).
4 Extend the flaps (Ref. TASK 27-50-00-866-008).
_ NOTE : Put the flap and slat control lever to the position 1.
____ 5 Read the new position of the spoiler .
_ The difference of positions gives the negative clearance X.
6 Retract the flaps (Ref. TASK 27-50-00-866-009).
_ 7 Install the LOCKING TOOL - FLAP/SLAT CONTROL LEVER
_ (98D27803000000).
8 If necessary, adjust the servocontrol (Ref Para. B).

(3) For the spoiler 5: X=0 +0 +0.5 mm (0.0000 +0.0000 +0.0196 in.).
NOTE : You must do this measurement at the closest point (point where
____ the gap between the spoiler and the flap is the smallest).
(a)
Adjustment of the clearance X without tool.
(b)
Adjustment of the clearance X with the SPOILER POSITION CHECK TOOL (98D27603000001).
1_ Adjust the servocontrol (Ref. Para. B) in order to measure:
X =4 +0 +0.5 mm (0.1574 +0.0000 +0.0196 in.).
2_ Adjust the servocontrol again (Ref Para. B) by half a turn
clockwise in order to get the clearance.

4 Extend the flaps (Ref. TASK 27-50-00-866-008).
_ NOTE : Put the flap and slat control lever to the position 1.
____ 5 Read the position of the spoiler 5.
_ The difference of positions gives the clearance X.
6 Retract the flaps (Ref. TASK 27-50-00-866-009).
_ 7 Install the LOCKING TOOL - FLAP/SLAT CONTROL LEVER
_ (98D27803000000).

B. If the clearance X is not correct, do this adjustment:
(1)
Write the clearance X.
(2)
Depressurize the hydraulic system that relates to the spoiler you adjust.
(a)
For the spoiler 1 or 5, depressurize the Green hydraulic system (Ref. TASK 29-23-00-864-001).
(b)
For the spoiler 2 or 4, depressurize the Yellow hydraulic system (Ref. TASK 29-24-00-864-001).
(c)
For the spoiler 3, depressurize the Blue hydraulic system (Ref. TASK 29-10-00-864-003).
(3)
Extend the related spoiler by hand (Ref. TASK 27-60-00-866-002).
(4)
On the servocontrol (1), remove the lockwire from the nut (3) and discard it.
(5)
Loosen the nut (3) and release the lockwashers (2).
(6)
Turn the rod (4) in the related direction (Refer to the NOTE below to find the number of turns of the rod (4)).
NOTE : If you do one turn of the rod (4), this moves the trailing
____
edge of the spoiler 8 mm (0.3149 in.).
(7)
Install the lockwashers (2) and TORQUE the nut (3) to 3 m.daN (22.12 lbf.ft). Do not safety the nut at this time.
(8)
Retract the related spoiler by hand (Ref. TASK 27-60-00-866-002).
(9)
Pressurize the hydraulic system that relates to the spoiler you adjust.
