27-70-00  GUST-LOCK AND DAMPER Back

A. System Function

The gust-lock and damper system (the system) locks the aileron, the elevator and the rudder control systems (when the aircraft is on the ground). This prevents damage because of strong winds.

B. System Components (Ref. Fig. 1 thru Fig. 13)

The sub-systems of the system are the gust-locks control mechanism, aileron gust-lock mechanism, rudder gust-lock mechanism and elevator gust-lock mechanism

C. System Operation

1. When you operate the gust-locks lever, the gust-locks control mechanism operates the:
   • Aileron gust-lock mechanism
   • Rudder gust-lock mechanism
   • Elevator gust-lock mechanism
   • Gust-locks microswitch of the take-off configuration warning-system
   • Power-lever balk mechanism of the engine power-control system
2. When the aileron, the rudder and the elevator gust-lock mechanisms are operated, spring pressure is applied to the aileron lock unit, rudder lock unit and elevator lock lever
   
   1. When the ailerons and the rudder are set to (approximately) the neutral position, the spring pressure will cause the lock units to lock their control systems.
   2. When the elevators are set to (approximately) the neutral position, the spring pressure will cause the elevator lock lever to lock their control systems.
3. When the gust-locks microswitch is operated, an input is given to the takeoff configuration warning system
4. When the power-lever balk mechanism is operated, only one engine power lever can be set above the flight idle position
