e. Connect the ends of the primary (13 or 17) and balance (18 or 19) control cables to the bellcrank
using bolts, washers, nuts and cotter pins. Allow the cable ends to rotate freely on the bellcrank.
f. Tighten the control cables at the balance cable turnbuckle (24) in the floor opening aft of the main
spar. Check cable tension per paragraph 5-11.
g. Install the access plate on the underside of the wing, the floor panel aft of the main spar, seat belt

5-11. RIGGING AND ADJUSTMENT OF AILERON CONTROLS.
(PIR-PPS50005-1, Rev. AF.)
CAUTION: VERIFY FREE AND CORRECT MOVEMENT OF AILERONS. WHILE IT WOULD
SEEM SELF-EVIDENT, FIELD EXPERIENCE HAS SHOWN THAT THIS CHECK IS
FREQUENTLY MISINTERPRETED OR NOT PERFORMED AT ALL. ACCORDINGLY,
UPON COMPLETION OF AILERON RIGGING AND ADJUSTMENT, VERIFY THAT
THE RIGHT AILERON MOVES UP AND THE LEFT AILERON MOVES DOWN
WHEN THE CONTROL WHEEL IS TURNED RIGHT; AND THAT THE LEFT
AILERON MOVES UP AND THE RIGHT AILERON MOVES DOWN WHEN THE
CONTROL WHEEL IS TURNED LEFT.
NOTE: Flap rigging and adjustment must be completed before starting aileron rigging and adjustment.
a. To check and adjust the rigging of the aileron controls, first set the right and left aileron bellcranks
at neutral position. (Ascertain that the control chains have been rigged per paragraph 5-5.) This may
be accomplished by the following procedure:
1. Remove the access plate to each aileron bellcrank located on the underside 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
forward 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 between
the bellcrank arm and rib. To do so, it
may be necessary to loosen a primary
control cable or the balance cable.
(This tool may be fabricated from
dimensions given in Figure 5-18.)
Neutral position of the bellcrank may
also be found by locating the center of
the balance cable attachment bolt or
the hole in the aft arm of the bellcrank
three inches from the face of the
adjacent rib.
