(2) Do a visual check of the spoiler hinge bearings.

Subtask 27-64-00-220-051-A

B. Check of the Spoiler Servocontrol Bearing and Hinge Bearings for too Much Play

Location of the Tools

NOTE: This check is for one surface only.
The same check is applicable to the other surfaces.

(1) On the 98D27603001000 LOAD APPLICATION TOOL - SPOILER, connect the 97A27003000007 GAGE,ASSY-PUSH-PULL97A27003000005 GAGE,ASSY - PUSH-PULL (or equivalent).
(2) Apply a force of 30 lbf (13.3447 daN) on the trailing edge, in the up direction.
(3) Make a mark of the pointer position on the SCALE - GRADUATED.
(4) Apply a force of 30 lbf (13.3447 daN) on the trailing edge, in the down direction.
(5) Make a mark of the pointer position on the SCALE - GRADUATED.
(6) Make sure that the play between the two limit positions is not more than 1.2 mm (0.0472 in.).
(7) If the measured play is more than the maximum permitted value:

Do the inspection/check of the bearings that attach the control surface to the structure, and
Do the inspection/check of the servocontrol bearings.

NOTE: The worn or damaged parts that you must replace are identified in the inspection/check AMM tasks applicable to the bearings (Ref. AMM TASK 27-64-41-200-001) (Ref. AMM TASK 27-64-42-200-001) (Ref. AMM TASK 27-64-43-200-001) (Ref. AMM TASK 27-64-44-200-001) (Ref. AMM TASK 27-64-45-200-001).

(a) If the defective bearing is a part of a spoiler, send the spoiler to the workshop to replace the bearing.
(b) If the defective bearing is the servocontrol eye-end-fitting bearing, replace the spoiler servocontrol eye-end (Ref. AMM TASK 27-64-51-960-801).
(c) Install the removed spoiler (Ref. AMM TASK 27-64-41-400-001) or (Ref. AMM TASK 27-64-42-400-001) or (Ref. AMM TASK 27-64-43-400-001) or (Ref. AMM TASK 27-64-44-400-001) or (Ref. AMM TASK 27-64-45-400-001).
(d) Go to Para. 4.B. to make sure that the measured play is not more than the maximum permitted value.

5. Close-up
