7 - FLAP SYSTEM
The flap system is made up of an electric actuator, a shunt and by a position
indicator instrument.
The actuator is installed in the tail cone in correspondence with the baggage
bulkhead and, controls a system of pushrods that initiate flap extension. Mi-
croswitches positioned within the actuator automatically interrupt current
flow when flaps reach “all-out” or “all-in” positions.
A bowden-type cable issuing from the flap actuator controls flap position in-
dicator located on the right side of the instrument panel.
Flap extension shunt is supplied by the primary bus bar through a breaker
and is located on the instrument panel.
Shunt must be activated until desired position is reached and read on instru-
ment: 0°, TO or FULL.
During flap retraction, shunt supplies the actuator until flaps are completely
retracted.
