Description
The GSA 86 servo actuator, when mated with the GSM 85(A) servo gearbox, drives a single flightcontrol axis of the airplane, or its associated trim. Once installed into the aircraft, the GSA 86 servo actuator may be easily removed for maintenance, without removing or de-rigging the GSM 85(A) servo gearbox. Note that while the GSA 86 is removed, it is recommended to use the Servo Gearbox Protective Cover (P/N 145-00807-00) to cover the opening of the GSM 85(A). The protective cover is included with the GSM 85(A) unit, and is designed to prevent foreign objects from falling into the GSM 85(A). The engagement of the drive clutch in the GSM 85(A) is controlled by a solenoid in the GSA 86.
A slip-clutch allows the capstan to rotate independently of the GSA 86 whenever sufficient force is applied to the capstan. This allows the pilot to override the operation of the GSA 86 in the event of a malfunction by applying sufficient force to overcome the slip-clutch setting.
