D. Removal of the aileron balance cable (4) may be accomplished by the following procedure:
1. Ascertain that the access plates are removed from the aft underside of each wing at stations
72.0, 115.5 and 139.50. Also, the fairing from between the underside of the fuselage and each
wing.
2. Remove the floor panel from the right side of the fuselage aft of the main spar.
3. If tension exists in the cable, rotate the turnbuckle barrel on the forward arm of either aileron
bellcrank at station 139.5 in the wing to slacken the cable. Then disconnect the cable from
each bellcrank by removing cotter pin, nut, washer and clevis bolt or by disassembling the
turnbuckle.
4. Remove the cotter pin cable guard from the cable pulley by reaching through the access hole in
each wing at station 115.50.
5. Remove the cotter pin cable guard from the left and right pulleys of the balance cable at
fuselage station 135.0.
6. If an Autopilot roll servo is attached to the balance cable, remove the slot head screws from the
bridle cable clamps at the center of the fuselage. Remove the safety sleeves inboard of each
clamp.
7. Draw the cable through the fuselage and each wing. Use caution when drawing the end of the
cable through the rub block at wing station 78.0.
5-10. Installation Of Aileron Control Cable (Refer to Figure 5-6.)
A. Installation of the aileron balance cable may be accomplished by the following procedure:

2. With the cable positioned on both the left and right pulleys in the fuselage at station 135.0,
install the cotter pin cable guards.
3. Attach the ends of the cable to the forward end of the bellcrank in each wing by assembling
turnbuckles and/or securing with clevis bolt, washer, nut and cotter pin. Do not set cable
tension at this time.
NOTE: Do not tighten turnbuckle fork ends on bellcrank so tight that the end cannot rotate.
4. By reaching through the access opening in each wing at station 11.5, position the cable around
the upper pulley of the cluster and if the primary control cable is installed, install the cotter pin
cable guard.
5. If an autopilot roll servo is part of the airplane's equipment, attach the bridle cable to the
balance cable with the use of the installation instructions given in Electronics Section.
B. Installation of the left and/or right primary control cables (3 and 6) that lead from the fuselage into
the wings may be accomplished by the following procedure:
1. Draw the cable through the wing into the fuselage.
2. Install the cable pulley in the fuselage, forward of the rear spar support bulkhead at station
135.0. For the left pulley, position the cable and pulley and secure with bolt, washer and nut.
For the right pulley, position the cable and pulley in the bracket and secure pulley with bolt,
washer and nut and then attach the bracket assembly to the bottom skin of the fuselage and
spar support bulkhead using screws. Ascertain that cotter pin cable guards are installed
