 C. Adjustment of the Outboard Servocontrol of the Right Elevator
 NOTE : At this step, the inboard servocontrol (Yellow) is in the damping____ mode. The outboard servocontrol (Blue) is in the active mode.
 (1) In order to taking-up the play of the servocontrol attachment, loosen the servocontrol attachment bolts on the two ends (Ref. TASK 27-34-51-000-001).
 (2) 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.
 (3) 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.
 (4) Remove the LOAD APPLICATION TOOL - ELEVATOR, AILERON, RUDDER (98D27303000001).
 NOTE : Use the new elevator neutral position written on the tail cone____ to do the adjustment.

 (f)
 Put the gauge (12) (5th mark) between the setting bar (10) and the abutment block (8).

 (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).

 (2)
 Install the LOAD APPLICATION TOOL - ELEVATOR, AILERON, RUDDER (98D27303000001) at the trailing edge of the elevator between the two servocontrols.

 (3)
 Remove the pointer of the LOAD APPLICATION TOOL - ELEVATOR, AILERON, RUDDER (98D27303000001) from the right side and install it on the left side, on the trailing edge of the elevator, in front of the tail cone. (Ref. Fig. 505/TASK 27-34-00-991-010)
