(Refer to Figure 5-6.)
A. Remove the rear seats, and seat rails, carpet and floor panel from the left side of the fuselage aft of
the main spar.
B. To remove the right and/or left primary control cable(s) (6 or 3) within the fuselage from station
50.0 to station 126.5, the following procedure may be used:
1. Remove the front seats and lay back enough floor carpet left of the nose wheel well to enable
the removal of the first left floor panel aft of the forward bulkhead.
2. Disconnect the desired cable at the turnbuckle where it connects to the sprocket chain at station
50.0.
3. Remove the cable guard (15) at the pulley cluster just aft of the forward cabin bulkhead, station
50.5, and at the cluster aft of the main spar, station 115.75.
4. Disconnect the cable from the cable leading into the wing at the strap fitting (7) at station
126.5 by removing cotter pin, nut and bolt.
5. Draw the primary cable back through the fuselage.
C. To remove the right and/or left primary control cable from either wing, the following procedure
may be used:
1. Remove the access plates from the aft underside of the wing at stations 72.0, 115.5 and 139.5
and the fairing strip from between the underside of the fuselage and wing.
2. If tension exists in the cable, rotate the turnbuckle barrel on the aft arm of the aileron bellcrank
at station 139.5 in the wing to slacken the cable. Then, disconnect the cable from the bellcrank
by removing cotter pin, nut, washer and bolt or by disassembling the turnbuckle.
3. Remove the cotter pin cable guard from the cable pulley by reaching through the access hole at
wing station 115.5.
NOTE: The aft end of each bellcrank and the turnbuckle assembly of the primary cable are
painted red to facilitate reinstallation.
4. In removing the right control cable (6), remove the pulley located at the aft butt end of the
wing by removing the nut, washer and bolt holding the pulley in its bracket.
5. Remove the cable pulley from the forward side of the rear spar support bulkhead at station
35.0. The pulley supporting the left control cable may be removed by removing the nut, washer
and bolt that holds the pulley in its mounting bracket. The pulley supporting the right control
cable may be removed by first removing the screws securing the mounting bracket to the
bottom fuselage skin and rear spar bulkhead, and then removing the nut, washer and bolt that
holds the pulley in the bracket.
6. If not previously disconnected, disconnect the cable from the forward control cable at fuselage
station 126.5 by removing the cotter pin, nut and bolt.
7. Draw the cable through the wing. Use caution when drawing the end of the cable through the
rub block at wing station 78.0.
