side of the wing, forward of the inboard end of the aileron by removing the plate
attachment screws.
2. Affix a bellcrank rigging tool, as shown in Figure 5-3 between the for-
ward arm of each bellcrank and the adjacent rib.
The slotted end of the tool fits
on the arm forward of and adjacent to the primary control cable end. The other
end of the tool is positioned so that the side of the tool contacts the aft side of the
bellcrank stop.
The bellcrank must be moved to allow a snug fit of the tool be-
tween the bellcrank arm and rib. To do so, it may be necessary to loosen a pri-
mary control cable or the balance cable.
(This tool may be fabricated from di-
mensions given in Figure 5-18.)
Neutral position of the bellcrank may also be
found by locating the center of the balance cable attachment bolt orthe hole in the
aft arm of the bellcrank three inches from the face of the adjacent rib.
b. With eachbellcrank set at neutral, the ailerons maybe checked and adjusted
for neutral as follows:
1. Ascertain that the bellcrank rigging tool fits snug between the bellcrank
and the rib.
2. Place an aileron rigging tool as shown in Figure 5-4 against the under-
side of the wing and aileron as close as possible to the inboard end of the aileron
without contacting any rivets.
The tool must be positioned parallel with the wing
ribs with the aft end of the tool even with the trailing edge of the aileron.
(This
tool may be fabricated from dimensions given in Figure 5-19.)
3. With the aileron control rod connected between the bellcrank and aileron,
check that the surface of the wing contacts the tool at its forward surface and at
the spacer, and the trailing edge of the aileron contacts the aft end of the tool. The
aileron is neutral at this position.
