E. Installation of the Tools
(1) Make sure that there is no warning related to the LGCIUs on the upper ECAM display unit.
(2) Install the LOAD APPLICATION TOOL - ELEVATOR, AILERON, RUDDER (98D27303000001) as follows: - at the trailing edge of the elevator - between the two servo controls.
(3) Install the CHECK TOOL - AILERON, ELEVATOR, RUDDER (98D27303003001) or CHECK TOOL (ORAP) - AILERON, ELEVATOR, RUDDER (98D27303022000) on the trailing edge of the elevator.
NOTE : Clean and make the tail-cone upper surface moist before you____ attach the tool.
(4) Put the PIN-SIDE STICK LOCKING (98D27903500000) on the CAPT and F/O sidestick controllers.
(5) Put the warning notices on the CAPT and F/O side sticks to tell persons not to touch the side sticks.
(6) Put a warning notice on the pitch trim control wheels to tell persons not to use the pitch trim.
4. Procedure_________

A. Check of the Elevator Servo Controls and Hinge Bearings for General Condition
(1) Make sure that the liner is in the correct position between the attachment hardware of the bearings (no migration of the liner).
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 R If you can see the liner, replace the related servo control (Ref. TASK 27-34-51-000-001) (Ref. TASK 27-34-51-400-001) or hinge arm end fitting (Ref. TASK 55-16-42-000-001) (Ref. TASK 55-16-42-400-001).

B. Check of the Elevators for too much Play R NOTE : For monitoring and follow up of the play at the elevator trailing
____ R edge, it is recommended that the operator record in its own R documentation the values measured.
(1) On the maintenance panel 50VU, release the HYD LEAK MEASUREMENT/B pushbutton switch (the OFF legend comes on).
NOTE : At this time, the inboard servo controls are pressurized:
____ -the Green hydraulic system for the left elevator.
-the Yellow hydraulic system for the right elevator. NOTE : If you see oscillations when the servo control is in active
____ mode, do a check of these oscillations.(Ref. TASK 27-34-00-200-002)
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.
(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.
(8)
If the distance is more than 7 mm (0.2755 in.) between the two positions:
(a) For the left elevator: 1 Replace the green elevator servo control (Ref. TASK 27-34-51-
_ 000-001) (Ref. TASK 27-34-51-400-001).
2 If the distance stays more than 7 mm (0.2755 in.) do a check
_ of the green elevator servo control fitting (Ref. TASK 27-34-51-200-001).
3 If the distance stays more than 7 mm (0.2755 in.) do a check
_ of the elevator fitting (Ref. TASK 27-34-41-200-001).
NOTE : This 7 mm (0.2755 in.) value includes 4 mm (0.1574 in.)
____ of surface bending as the result of 30 daN (67.4426 lbf) applied force.
(b) For the right elevator: 1 Replace the yellow elevator servo control (Ref. TASK 27-34-51-
_ 000-001) (Ref. TASK 27-34-51-400-001).
2 If the distance stays more than 7 mm (0.2755 in.) do a check
_ of the yellow elevator servo control fitting (Ref. TASK 27-34-51-200-001).
3 If the distance stays more than 7 mm (0.2755 in.) do a check
_ of the elevator fitting (Ref. TASK 27-34-41-200-001).
NOTE : This 7 mm (0.2755 in.) value includes 4 mm (0.1574 in.)
____ of surface bending as the result of 30 daN (67.4426 lbf) applied force.
