AILERON.
REMOVAL OF AILERON. (Refer to Figure 57-2.)
1. Disconnect the aileron control rod at the center hinge by removing the nut, washers, and bolt from the rod
end bearing. To simplify installation, note the location of the washers.
2. Support the aileron and disconnect the inboard, outboard and center aileron hinges by removing the nuts,
washers and hinge bolts. Remove the aileron by lifting and pulling aft.
INSTALLATION OF AILERON. (Refer to Figure 57-2.)
1. Position the aileron in the wing and install the bolts, washers, and nuts at the hinges.
2. Connect the aileron control rod to the aileron at the center hinge brackets with bolt, washers and nut.
AILERON BALANCE. (Refer to Figure 57-3.)
The ailerons have been statically balanced at the time of installation at the factory and normally should not
require rebalancing. Where possible the ailerons were set with the balance weight on the heavy side of the limits
to permit limited repair or paint touch-up without adjusting the balance weight. It should be noted, however. that
spare ailerons are delivered unpainted and the static balance will not necessarily fall within the limits provided.
The completed ailerons including paint should be within the limits given in Figure 57-3. If the ailerons are not to
be painted, the balance weight will probably require adjustment. All replacement ailerons or ailerons that have
been repainted or repaired should be rebalanced according to the procedures given in this chapter. The static
balance of the ailerons must be as specified in the figures referenced above.
Before balancing any control surface, it must be complete including tip, trim/servo tabs as applicable and tab
actuating arms or push rods with bearings as applicable and all optional equipment which is mounted on or in the
control surface when it is flown, including paint, position lights and wiring, static wicks, scuff boots, etc.
If optional equipment is added or removed after balancing, the control surface must be rebalanced. During
balancing, trim servo tabs must be maintained in the neutral position.
