D. Balancing (Refer to Figure 2.)
WARNING: ALL CONTROL SURFACES THAT HAVE BEEN REPLACED OR REPAINTED MUST
BE BALANCED BEFORE INSTALLATION.
Position the aileron on the balancing fixture in a draft free area and in a manner which allows
unrestricted movement of the aileron. Place the tool (see 95-00-00, Figure 2) on the aileron,
avoiding rivets, and keep the beam perpendicular to the hinge centerline. Read the scale when the
bubble level has been centered by adjustment of the movable weight and determine the static
balance. If the static balance is not within the limits specified in Figure 2, proceed as follows:
(1) Leading edge heavy: This condition is highly improbable; recheck measurements and
calculations.
(2) Trailing edge heavy: There are no provisions for adding weight to balance weight to counteract
a trailing edge heavy condition. Therefore, it will be necessary to determine the exact cause of
the unbalance. If the aileron is too heavy because of painting over old paint, it will be
necessary to strip all paint from the aileron and repaint. If the aileron is too heavy resulting
from repair to the skin or ribs, it will be necessary to replace all damaged parts and recheck
the balance.
2. Wing Flap
(Refer to Figure 1.)
CAUTION: CONTROL SURFACE SKINS MUST BE REPLACED IF THEY SUSTAIN DAMAGE OR
ARE CRACKED.
A. Removal
(1) Extend the flaps to their fullest degree and remove the bolt and bushing from the rod end
bearing.
(2) Remove the nuts, washers, bushing and hinge bolts that hold the flap to the wing assembly.
(3) Pull the flap straight back off the wing.
B. Installation
(1) Replace the wing flap by placing the flap onto its proper position and inserting the hinge bolts,
bushings, washers and nuts.
(2) With the flap control in the full flap position, place the bushing on the outboard side of the rod
end bearing and insert and tighten the bolt.
(3) Operate the flap several times to be certain it is operating freely. (Refer to 27-50-00, Wing Flap
Controls, Rigging and Adjustment.)
