(2) Flap Control Cable:
(a) If the center seats and floor panel have not been removed, remove the seats and the
screws securing the floor panel.
(b) Disconnect the flap tension spring from the cable, if not previously disconnected, by
extending the flaps to relieve spring tension.
(c) Retract the flap. Use caution as forward pressure will be on the handle with the spring
disconnected.
(d) Disconnect the cable from the chain by removing cotter pin, nut, clevis pin and bushing.
(e) Remove the flap handle bracket and trim control wheel cover.
(f) Remove the aft heat deflectors on each forward floor tunnel by sliding far enough to
release the spring fasteners.
(g) Lift the aft section of the tunnel carpet far enough to remove the screws securing the
tunnel cover that is between the flap handle and the spar cover. Remove the cover.
(h) Remove the cotter pin cable guard from the flap cable pulley located inside the floor
tunnel just ahead of the spar housing.
(i) Remove the cable rub blocks located in the floor opening on the aft side of the spar
housing by removing the attachment screws.

Disconnect the cable turnbuckle from the handle and remove the bolts securing the bracket to
the floor tunnel.
B. Installation
(1) Flap Torque Tube Assembly:
(a) Install the chain sprockets with chains on the torque tube and secure with bolts, washers
and nuts.
(b) Slide the tube stop fittings on their respective ends of the torque tube.
(c) Ascertain that one bearing block fitting is installed between its attachment brackets.
(d) Slide the other bearing block over its respective end of the torque tube.
(e) Position the torque tube by placing the end with the bearing block on it between the
mounting bracket and sliding the other end into the previously attached bearing block.
(f) Position the remaining bearing block and secure with bolts, washers and nuts.
(g) Push the torque tube cranks (arms) on each end of the torque tube and slide the stop
fitting in place. Align the bolt hole of the crank and stop fitting with the holes in the torque
tube, and install bolts. The holes in the stop fitting are elongated to allow the stop fitting to
be pushed against the bearing block thus allowing no side play of the assembly. Tighten
the bolt assemblies on the stop fittings.
(h) Install the tube support blocks on their support brackets and secure with bolts.
(i) Connect the flap return spring to the return chain and/or at the spar housing.
(j) Connect the control cable end to the tension chain and secure with bushing, clevis bolt,
nut and cotter pin.
(k) Pull the flap handle full back and connect the tension spring. Release the flap handle to
the forward position.
(l) Connect the flap control tube to the flap and/or torque tube crank and secure. The bolt
and bushing that connects the control tube to the crank is installed through a hole in the
side of the fuselage located over the torque tube.
