This indicator, illuminated for night flights, allows the pilot to determine the flap position. The "retracted", "take-off" and "landing" positions are marked on the indicator. The latter receives information about the position of the flap main bellcrank through a potentiometer and a printed circuit. S / N 1 - 560 Pre-Kit OPT10 912900 (Detail C) The printed circuit is integrated into the indicator. S / N 561 - 9999 and S / N 1 - 560 Post-Kit OPT10 912900 (Detail D) The printed circuit is located on the internal L.H. side of the pedestal. "AVIAC" flap actuator The potentiometer is secured on the lower side of the actuator support. "LPM I" flap actuator The potentiometer is integrated into the actuator. C. Relays (Figure 1) Two relays, located under the fuselage and attached under the rear bench seatpan (or to frame C3 if muffler exhaust option is installed), circuit breaker CB 34, marked "FLAPS" (located on L.H. side circuit breaker panel) and a fuse (located on the fuse panel) protect the flap electrical circuit. D. Aural warning unit The flap system also consists of an aural warning microswitch. The aural warning unit is activated when the landing gear is in "retracted" position and the flaps are extended beyond 15°. The microswitch is connected to the landing gear aural warning circuit. It triggers a continuous aural signal diffused by the warning loudspeaker located on the upper duct. 1 - Flap indicator and control 2 - Warning microswitch 3 - Flap actuator 4 - Main bellcrank 5 - Outboard bellcrank 6 - Input rod 7 - Relay e COMPONENT QTY AREA ACCESS DOOR REFERENCE |
