AILERON AND GEAR TRIM TAB TRAVEL
(refer to figure
NOTE
This procedure is valid for LH aileron. For
RH aileron is similar.
1.Disconnect external AC power supply from aircraft
(refer to manual
).
2.Isolate hydraulic supply (refer to manual
3.Fit Aileron check template (AGE NO. 00064) on top
surface of right and left outer wing.
4.Put the double side adhesive tape on the top surface
of the aileron and the trim tab/geared tab, non in
contact with their rivets, and position on it the digital
inclinometers (AGE NO. 00061), parallel to the
template.
5.Acting on control wheel set the aileron surfaces in
neutral position. Aileron displacement should be 0 ° ±
0.25° as read on the templates.
6.Reset the inclinometer (AGE NO. 00061), then
remove the templates.
7.With aileron surfaces in neutral position check that the
clearance between wing trailing edge and aileron
surface is 0.394 in +0.059/-0.157 in (10 mm + 1.5/-4
mm).
8.Turn LH (RH) control wheel fully right and keep it in
this position:
-the right aileron must travel 26 ° ± 1° upwards and
the left aileron must travel 19 ° ± 1 ° downwards
position;
-the right gear tab must travel downwards 19.75 ° ±
1° and left gear trim tab must travel upwards
15.75° ± 1 ° (Make the difference between the
readings of the inclinometers (AGE NO. 00061)).
