INSTALLATION OF WING FLAP CONTROLS. (Refer to Figure 27-19.)
1. The flap torque tube assembly may be installed by the following procedure:
A. Install the chain sprocket with chain 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.

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

bearing blocks thus allowing no side play of the assembly. Tighten the bolt assemblies on the stop
fittings.

located over the torque tube.
2. To install the flap handle with bracket, place the assembly on the floor tunnel and secure with bolts.
3. The flap control cable may be installed by the following procedure:
A. Attach the cable and turnbuckle to the flap handle arm and secure with clevis bolt, bushing*,
