4. Procedure
_________
(Ref. Fig. 629/TASK 57-52-00-991-031) Subtask 57-52-00-100-050
A. Preparation for Inspection
(1) Use a MISCELLANEOUS (Material No. 19-003), made moist with CLEANING AGENTS (Material No. 11-026) to clean the component interface and the adjacent area.
Subtask 57-52-00-200-052
B. Detailed Visual Inspection of the Actuator Lever Bushes and Actuator Splines
(1)
Before you do the inspection, move the actuator lever to approximately the 20 deg. flap position.
(2)
Inspect the actuator lever bushes for wear:
(a) Measure the sideplay of the actuator lever:
1_ If the dimension X is less than 2.40 mm (0.0944 in.) and there
is no wear or corrosion of the actuator output-shaft splines,
the actuator is in a serviceable condition.
2_ If the dimension X is between 2.40 mm (0.0944 in.) and 3.80 mm
(0.1496 in.), refer to (Ref. ISB 57-1108).
3_ If the dimension X is more than 3.80 mm (0.1496 in.), or the
actuator output-shaft splines are more than 50% corroded,
refer to AIRBUS INDUSTRIE for instructions.
