of the tee bar assembly (5) by removing the nut, washer and bolt (3). Pull the tube from
the flexible joint.
(b) If removing the left control tube, slide the stop (6) from the tube.
(c) Should wires from the various Autopilot systems be installed in the control tube,
disconnect them at the quick disconnect terminals behind the instrument panel. Draw the
wires back into the tube and out through the forward end of the tube.
(d) Remove the control wheel assembly from the instrument panel.
(2) The tee bar (5) with assembled parts may be removed from the airplane by the following
procedure:
(a) Remove the access panel to the aft section of the fuselage.
(b) Relieve the cable tension from the stabilator control cables (11) at one of the stabilator
cable turnbuckles in the aft section of the fuselage.
(c) Relieve tension from the aileron control cables (12) chains (7 and 8) and at the turnbuckle
(9) that connects the chains at the top of the tee bar (5).
(d) Disconnect the control chains from the control cables where the chains and cables join,
by removing the cotter pins, nuts, bolts and bushings.

which are through each side of the floor tunnel, and lifting it up and out through the right
side of the cabin.

(a) Position the tee bar assembly into place from the right side of the cabin and secure in
place with attaching bolts (15), washers and nuts inserted in through each side of the floor
tunnel.
(b) Connect the stabilator controls (11) to the lower end of the tee bar with bolt, washer, nut
and cotter pin (16). Allow the cable ends to rotate freely.
(c) Place the aileron control cables (12) around the pulleys (13) that attach to the lower

(d) Install the control wheel with its tube per Step (2), below.
(e) Place the control wheels in neutral (centered) position and install the aileron control
chains (7 and 8) on the control wheel sprockets (17 and 18) and idler crossover sprockets
(19 and 21). This turnbuckle (9) must be centered between the two control wheel
