Brief Description: Installing Roll Servo - Right Wing
Every GSA 28 is supplied with a 011-02951-00 stop bracket kit. The intention of this stop bracket is to create redundant stops for the servo control arm that prevents the servo’s arm from going over-center relative to the push rod connected to the servo’s arm. It is highly recommended this part gets installed with every push-pull application. The stops created by installing this bracket are redundant in the sense that the aircraft’s built-in stops should always be used as the primary means of limiting travel of the servo’s control arm. This stop bracket limits the motion of the standard control arm to 100° total travel. This bracket should be positioned such that the stop bracket flanges are as close as practical to being equal distance from the servo’s control arm while at the center of travel. Also, to prevent an over-center condition, the servo’s push rod should be as close as practical to perpendicular with the servo’s control arm while positioned at the center of travel. The position of this bracket can be adjusted in increments of 15°. If necessary, further adjustments can be made by changing the length of the push rod connected to the servo.
See Figure 11-6.2, and Figure 11-6.3 for more details.
After installation of the servo is complete, verify that the stop bracket does NOT impede the full movement of the associated control.
