4. Procedure_________
Subtask 27-14-00-210-052
A. Check for General Condition
(1) Do a visual check of the servo control bearings.
(2) Do a visual check of the aileron hinge bearings.
(3) Make sure that the that the liners are not damaged.
R R R NOTE : The liner is a coat of teflon between the bearing case and the____ ball. It lets the ball turn with a minimum of friction (self lubricating).
R R If you can see the liner, replace the related servo control (Ref. TASK 27-14-51-000-001) and (Ref. TASK 27-14-51-400-001).
Subtask 27-14-00-220-050
B. Check of the Aileron Servo Controls and Hinge Bearings for too much Play and Condition
(1) On the panel 24VU, release the FLT CTL/ELAC 2 pushbutton switch (the OFF legend comes on).
NOTE : The check is only given for one surface. Do the same____ operations for the other surface.
(2) Connect the SPRING SCALE ASSY (97A27902016000) or GAGE ASSY - PUSH-PULL (97A27003000000) or GAGE ASSY - PUSH-PULL (97A27003000001) to the LOAD APPLICATION TOOL - ELEVATOR, AILERON, RUDDER (98D27303000001) and apply 30 daN (67.4426 lbf) in the up direction on the trailing edge.
NOTE : If you see oscillations when the servo control is in active____ mode, do a check of these oscillations (Ref. TASK 27-14-00-200-001)
(3) Continue to apply this force and set the dial indicator to zero.
(4) Release the force.
(5) At the same position, apply 30 daN (67.4426 lbf) in the down direction on the trailing edge.
(6) Continue to apply this force and read the value on the dial indicator.
(7) Release the force on the trailing edge.
(8)
Change the servoing of the ailerons as follows:
(a)
On the panel 24VU, push the FLT CLT/ELAC 2 pushbutton switch (the OFF legend goes off).
(b)
On the panel 23VU, release the FLT CTL/ELAC 1 pushbutton switch (the OFF legend comes on).
(9)
At the same position, apply 30 daN (67.4426 lbf) in the up direction on the trailing edge.
(10)
Continue to apply this force and set the dial indicator to zero.
(11)
Release the force.
(12)
At the same position, apply 30 daN (67.4426 lbf) in the down direction on the trailing edge.
(13)
Continue to apply this force and read the value on the dial
indicator.
(14)
Release the force on the trailing edge.
(15)
For each measurement, if the distance is more than 10 mm (0.3937 in.) between the two positions:
-repair the structure/aileron, structure/servo control or servo control/aileron bearings (Ref. TASK 27-14-41-200-001), (Ref. TASK 27-14-51-200-001).
NOTE : This 10 mm (0.3937 in.) value includes 4 mm (0.1574 in.) of
____ surface bending as the result of 30 daN (67.4426 lbf) applied force.
