D. Adjust the turnbuckles, located in the access opening just aft of the main spar, of the primary and
balance cables to their proper cable tension and maintain neutral-center position of the control
wheels. To obtain neutral position of both control wheels, it may also be necessary to adjust the
roller chain turnbuckle located between the control wheel sprockets. During adjustment, obtain a
little more tension on the primary control cables to hold the bellcranks in neutral against the
rigging tools, finishing with even tension on all cables.
E. Tighten the bolts to secure the idler cross-over sprockets.
F. Remove the aileron bellcrank rigging tool from each wing.
4. Check the ailerons for correct travel from neutral per dimensions given in Figure 27-4 by the following
procedure:
A. Center the bubble of a protractor over the surface of an aileron at neutral position and note the
reading.
B. Move the aileron full up and down, and check the degree of travel for each direction. The degree
of travel on the protractor is determined by taking the difference between the protractor reading at
neutral and up, and neutral and down. The bubble must be centered at each reading.
C. Should the travel not be correct, the travel may be set by rotating the bellcrank stops in or out.
Stops are located in the wing attached to the rib that is adjacent to the aileron bellcrank.
D. Repeat this procedure for the other aileron.
