the springs are the same length.

Aileron Servo Tabs
Ref. Figure 7-3
A ground adjustable servo tab is
attached to each aileron. While its
primary function is to lighten aileron
control loads, it can be adjusted to
compensate for an out-of-trim roll
condition. A wing high attitude of either
wing may be corrected by adjusting the
applicable trim tab down. Adjusting the
tab up will correct a low wing attitude.
Begin with both tabs in neutral position
(straight with trailing edge of aileron).
AILERON
Ref. Figur
e 7-4
An all-metal aileron is installed outboard
of each wing flap. Each aileron operates
on bearing equipped hinges which are
attached to the aft wing spar at three
points. A balance weight is installed in
the inboard and outboard leading edge of
each aileron to prevent flutter. Both
ailerons have a servo-tab to lighten
control forces.
* NOTE *
The left and right ailerons are
interchangeable.
Aileron removal is accomplished as follows:
A. Remove the bolt attaching the pushrod
to the aileron horn at the center hinge.
B. Remove the bolt attaching the servo-tab
pushrod to the aileron.
* NOTE *
The pushrods should remain
with the wing. Do not change
pushrod lengths unless
absolutely necessary.
C. Identify the aileron as either left or right.
D. Remove the nuts and washers from the
three aileron hinge bolts.
E. While supporting the aileron well,
remove the three hinge bolts. If
assistance is not available, remove the
center bolt last to make the job easier.
Installation of the aileron is the reverse of the
removal procedure. In the event push rod
length has been altered, streamline trailing
edge of ailerons with trailing edge of wing
and flap and secure with a temporary lock.
Adjust push rod length to align attaching bolt
hole with hole in aileron hinge fitting, when
aileron is in neutral position. Recheck
aileron rigging.
