4.2 Flap control
Flap control system is push-pull type. The torque tube (1), connects the two moving surfaces and hinges on two braces (2)
rigidly attached to fuselage structure. Bolt, nut and cotter pin secure link. Rotation is transmitted through a push-rod (3)
whose position is adjusted via an electric linear actuator (4) governed by a switch on instrument panel.
Two push-pull rods (6) are connected to the ends of the torque tube (1) and are located in the area between wing and
fuselage thus facilitating inspection.
The two push-pull rods controlling flap movement feature an adjustable linkage just before the roller bearings allowing
trailing edge alignment.
