-release the FLT CTL/ELAC 1 and FLT CTL/SEC 1 pushbutton switches (on these pushbutton switches, the OFF legends come on).
(3)
On the overhead panel 24VU:
-push the FLT CTL/ELAC 2 and FLT CTL/SEC 2 pushbutton switches (on these pushbutton switches, the FAULT and OFF legends are off).
NOTE : At this step, the inboard servocontrol (Green) is in the
____ active mode; the outboard servocontrol (Blue) is in the damping mode.
(4)
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).
(5)
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.
(6)
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.
(7)
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.
(8)
If not, adjust the inboard servocontrol as follows: (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 (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 (9) Remove the GAUGE-ELEVATOR NEUTRAL SETTING (98D27309002000).
(10) Adjust the left Green 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 a part of the transducer-unit.
____
If you cannot, adjust the length of the control rod (4) as follows: Subtask 27-34-00-869-095
1_ Cut and discard the lockwire from the nuts (2).
2_ Remove the bonding lead from the lock washer (3).
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 washers (3) and tighten the nuts (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).
F. Servoing Change
(1)
On the maintenance panel 50VU, push the HYD/LEAK MEASUREMENT VALVES/B pushbutton switch and release the HYD/LEAK MEASUREMENT VALVES/G pushbutton switch. (the OFF legend of the HYD/LEAK MEASUREMENT VALVES/B pushbutton switch goes off, the OFF legend of the HYD/LEAK MEASUREMENT VALVES/G pushbutton switch comes on).
(2)
On the overhead panel 24VU:
(a) Release the FLT CTL/ELAC 2 and FLT CTL/SEC 2 pushbutton switches (on these pushbutton switches, the OFF legends come on). 中國航空網 www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320飛機維護手冊 AMM FLIGHT CONTROLS 飛行操縱3(38)
