14.4 FLAP SYSTEM
The flap surfaces are constructed of composite materials, same as the wings. Each flap is
attached to the wing by 2 hinges. Both flaps are mechanically interconnected.
Flap operation is by an electric motor installed in the lower fuselage behind the seats.
Through a reduction gearbox and a screw jack, the flap motor transmits the motion to the
flap‘s interconnecting torque shafts.
An angular position transducer installed near the gearbox transmits the flap position to the
flap position indicator on the instrument panel.
A magnetic circuit breaker of 7 amps is installed on the instrument panel, and protects the
flap motor and system from overload. This circuit breaker can be reset in flight.
Flap switch, spring loaded to centre OFF position. Switch up (momentarily) to retract
flaps. Switch down (momentarily) to extend flaps.
The flap motor and screw jack unit includes end of travel switches to cut the current once
the flap up or full down positions is reached. Flap position indicator, is an electrical
instrument installed on the instrument panel and fed in the ON position of the Master
Switch by the flap transducer‘s position.
