 (g) Turn the adjuster knob (11) to lower the setting bar (10) until:
 1_ The pad (9) touches the THS.
 2_ The bottom of the setting bar (10) is to be 5 mm (0.1968 in.) from the abutment block (8).
 (8) Install the LOAD APPLICATION TOOL - ELEVATOR, AILERON, RUDDER (98D27303000001) at the trailing edge of the elevator, between the two servocontrols.
 4. Procedure_________
 Subtask 27-34-00-820-063-A
 A. Adjustment of the Inboard Servocontrol of the Right Elevator. 
R R R R  (1) On the maintenance panel 50VU, release the HYD/LEAK MEASUREMENT VALVES/G and HYD/LEAK MEASUREMENT VALVES/B pushbutton switches. (the OFF legends of the HYD/LEAK MEASUREMENT VALVES/G and HYD/LEAK MEASUREMENT VALVES/B come on).
 NOTE : At this step, the inboard servocontrol (Yellow) is in the____ active mode; the outboard servocontrol (Blue) is in the damping mode.
 (2) In order to taking-up the play at the servocontrol attachment, loosen the servocontrol attachment bolts on the two ends (Ref. TASK 27-34-51-000-001).
 (3) Apply a force of 20 +10 -10 daN (44.9617 +22.4808 -22.4808 lbf) with the LOAD APPLICATION TOOL - ELEVATOR, AILERON, RUDDER (98D27303000001) to the down direction.

 

 (4)
 Tighten the servocontrol attachment bolts while you keep the force in the down direction (Ref. TASK 27-34-51-400-001), then release the force.

 (5)
 Put the gauge (12) between the upper surface of the elevator and the bottom of the setting bar (10). The neutral position indication is 5 plus or minus 0.5.

 (6)
 If not, adjust the inboard servocontrol:
 (Ref. Fig. 501/TASK 27-34-00-991-001)

 (a)
 Remove the lockwire from the lock nut (2).

 (b)
 Loosen the lock nut (2).

 (c)
 Disengage the lock washer (3).

 (d)
 Turn the rod (4) (in the correct direction) until the upper surface of the elevator touches the gauge (12) at 5 mm position.

 (e)
 Engage the lock washer (3).

 (f)
 TORQUE the lock nut (2) to between 3 and 3.5 m.daN (22.12 and

 

 25.81 lbf.ft)
 (g) Make sure that the torque does not change the adjustment. R (7) Remove the GAUGE-ELEVATOR NEUTRAL SETTING (98D27309002000).
 (8) Adjust the right Yellow inboard servocontrol to the new neutral position: (Ref. Fig. 505/TASK 27-34-00-991-010)
 (a)
 On the tail cone, record the position of the elevator, and identify it as the nominal position.

 (b)
 On the tail cone, mark the new elevator neutral position at 9 +0.5 -0.5 mm (0.3543 +0.0196 -0.0196 in.) above the nominal position as recorded before.

 (c)
 Loosen the lock nut (2).

 (d)
 Disengage the lock washer (3).

 (e)
 Turn the rod (4) (in the correct direction), until the pointer is aligned with the new elevator position mark on the tail cone. (Ref. Fig. 505/TASK 27-34-00-991-010)

 (f)
 Engage the lock washer (3).

 (g)
 TORQUE the lock nut (2) to between 3 and 3.5 m.daN (22.12 and

 

 25.81 lbf.ft)
 (h)
 Make sure that the torque does not change the adjustment.

 (i)
 Safety the lock nut (2) with Lockwire-corrosion resistant steel dia 0.8 mm (0.03 in.).

 (j)
 Make sure that you can engage/disengage the rigging pin easily into/from the elevator position transducer-unit (1). (Ref. Fig. 502/TASK 27-34-00-991-009)

 NOTE : The rigging pin is part of the transducer-unit.
____
 If you cannot, adjust the length of the control rod (4):

 1_ Cut and discard the lockwire from the nuts (2).
 2_ Remove the bonding lead from the lock washer (4).
 3_ Loosen the nuts (2).
 4_ Disengage the lock washers (3).
 5_ Turn the control rod body (4) until you can engage freely the
 rigging pin in the transducer unit (1).
 6_ Engage the lock washers (3) and tighten the nut (2) on the rod
 (4).
 7_ Make sure that you can engage/disengage freely the rigging pin
 into from the elevator position transducer-unit (1).
 8_ On the upper ECAM display unit, make sure that the ELAC 2
 PITCH FAULT warning is not shown.
 9_ Safety the nuts (2) with lockwire-corrosion resistant steel
 dia 0.8 mm (0.03 in.).

 10 Install the bonding lead on the washer (3).

 B. Servoing Change 
R R R R R  (1) On the maintenance panel 50VU, push the HYD/LEAK MEASUREMENT VALVES/B and release the HYD/LEAK MEASUREMENT VALVES/Y pushbutton switches. (the OFF legends of the HYD/LEAK MEASUREMENT VALVES/B goes off, the HYD/LEAK MEASUREMENT VALVES/Y comes on).
