Adjustment of the Spoilers

TASK 27-64-00-820-001-E
Adjustment of the Spoilers

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 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 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.

4. Procedure
Subtask 27-64-00-220-054-A ** ON A/C NOT FOR ALL
A. Measure the clearance or the interference U between the underside of the spoiler trailing edge and the upper surface of the flap.
   (1) For spoiler 1, measure the clearance U with the GAGE - FEELER.
  • The clearance U must be:
    U = 3.5 +0 mm or +1.5 mm (0.1378 +0.0000 in. or +0.0591 in.).
NOTE: You must do this measurement:
  • At the trailing edge of the spoiler (not titanium extension plate).
  • At the inboard end of the spoiler.
     (a) If necessary, adjust the servocontrol (Ref. Para. B).
   (2) For spoiler 2, measure the clearance U with the GAGE - FEELER.
  • The clearance U must be:
    U = 2 +0.5 mm or -0.5 mm (0.0787 +0.0197 in. or -0.0197 in.).
NOTE: You must do this measurement:
  • At the trailing edge of the spoiler (not titanium extension plate).
  • At the outboard end of the spoiler.
     (a) If necessary, adjust the servocontrol (Ref. Para. B).
   (3) For spoilers 3 and 4 measure the interference U.
  • The interference U must be:
    U = -2 +0.5 mm or -0.5 mm (-0.0787 +0.0197 in. or -0.0197 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) With the 98D27603000001 SPOILER POSITION CHECK TOOL.
       1 Install the 98D27603000001 SPOILER POSITION CHECK TOOL as follows:
  • On the upper surface of the wing
  • On the trailing edge of the spoiler
  • On the axis of the servocontrol.
       2 Set the needle of the dial gauge to the zero position.
       3 Remove the 98D27803000000 LOCKING TOOL-FLAP SLAT LEVER,INT. POSITION.
       4 Extend the flaps (Ref. AMM TASK 27-50-00-866-008).
NOTE: Put the flap and slat control lever to position 1.
       5 Read the new position of the needle of the dial gauge.
The difference of positions gives the negative clearance U.
       6 Retract the flaps (Ref. AMM TASK 27-50-00-866-009).
       7 Install the 98D27803000000 LOCKING TOOL-FLAP SLAT LEVER,INT. POSITION.
       8 If necessary, adjust the servocontrol (Ref. Para. B).
     (b) If the 98D27603000001 SPOILER POSITION CHECK TOOL is not available, do the adjustment (Ref Para.B) to get the negative clearance as follow:
       1 Initially adjust the servocontrol in order to measure:
U = 2 +0.5 mm or -0.5 mm (0.0787 +0.0197 in. or -0.0197 in.).
       2 Then adjust the servocontrol again by half a turn clockwise in order to get the negative clearance.
   (4) For spoiler 5 , measure the clearance U with the GAGE - FEELER.
  • The clearance U must be:
    U = 0 +0 mm or +0.5 mm (0.0000 +0.0000 in. or +0.0197 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) If necessary, adjust the servocontrol (Ref. Para. B).
       1 Initially adjust the servocontrol in order to measure:
U = 4 +0 mm or +0.5 mm (0.1575 +0.0000 in. or +0.0197 in.).
       2 Then adjust the servocontrol again by half a turn clockwise in order to get the clearance.
Subtask 27-64-00-820-054-A ** ON A/C NOT FOR ALL
B. If the clearance or the interference U is not correct, do this adjustment :
   (1) Write the clearance or the interference U.
   (2) Depressurize the hydraulic system that relates to the spoiler you adjust.
     (a) For spoiler 1 or 5, depressurize the Green hydraulic system (Ref. AMM TASK 29-23-00-864-001).
     (b) For spoiler 2 or 4, depressurize the Yellow hydraulic system (Ref. AMM TASK 29-24-00-864-001).
     (c) For spoiler 3, depressurize the Blue hydraulic system (Ref. AMM TASK 29-10-00-864-003).
   (3) Extend the related spoiler by hand (Ref. AMM 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 (0.3150 in.).
   (7) Install the lockwashers (2) and TORQUE the nut (3) to between 3.15 and 2.85 m.daN (23.23 and 21.02 lbf.ft ) T. Do not safety the nut at this time.
   (8) Retract the related spoiler by hand (Ref. AMM TASK 27-60-00-866-002).
   (9) Pressurize the hydraulic system that relates to the spoiler you adjust.
     (a) For spoiler 1 or 5, pressurize the Green hydraulic system (Ref. AMM TASK 29-23-00-863-001).
     (b) For spoiler 2 or 4, pressurize the Yellow hydraulic system (Ref. AMM TASK 29-24-00-863-001).
     (c) For spoiler 3, pressurize the Blue hydraulic system (Ref. AMM TASK 29-10-00-863-003).
   (10) Make sure that the clearance or the interference U is correct.

   (12) Extend the related spoiler by hand (Ref. AMM TASK 27-60-00-866-002).
   (13) TORQUE the nut (3) to between 9 and 8 m.daN (66.37 and 59.00 lbf.ft ) T and safety it with lockwire corrosion resistant steel dia 0.8 mm (0.03 in.).
   (14) Retract the related spoiler by hand (Ref. AMM TASK 27-60-00-866-002).
   (15) Pressurize the hydraulic system that relates to the spoiler you adjust.
