Figure 5-4. Aileron Rigging Tool
b. With each bellcrank set at neutral, the ailerons may be 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 underside 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.
4. Should the three points not contact, loosen the jam nut at the aft end of the control rod and
rotate the rod until the three points contact. Apply a slight up pressure against the trailing edge
of the aileron while making this adjustment. After adjustment, retighten the jam nut. The
ailerons may be allowed to “droop” by approximately 1/8 of an inch at this point.
