2. Description
Figure 1 shows the flap control system in the fuselage. Figure 2 shows the flap pushrods and
bellcranks in the wing. Figure 3 shows the flap actuator installation.
A. Flap Actuator
An electric actuator operates the flaps. The electric actuator is under the left passenger seat. A
mounting bracket on the left rear closing rib attaches the actuator to the structure.
The actuator has an electric motor. The motor has a reduction gear which turns a spindle. The
spindle operates a pushrod. The pushrod connects to an idler lever attaches to the rear main
bulkhead.
A cam attached to the pushrod operates five micro switches. The micro switches are part of the
flaps electronic control circuit.
B. Push-Rods and Bellcranks
The idler lever on the rear man bulkhead connects to four pushrods. Two of the pushrods connect
to the inboard ends of longer pushrods in the wing and the other two pushrods connect to the inner
flap bellcranks. Two short pushrods connect the inner flap bellcranks to the inner flap horns.
The long pushrods connect to flap bellcranks in the outer wing. A guide bearing holds each long
push-rod at the root rib. Two short pushrods connect the outer flap bellcranks to the flap horns.
