Servo Slip Messages
Condition: The servo shear screw may have failed if one or more of the following messages
persist:
1. PITCH SERVO SLIP
2. ROLL SERVO SLIP
3. YAW SERVO SLIP
Test the affected servo for a failed shear screw:
1. On the ground, engage the autopilot into level mode
2. from the exterior of the airplane, grasp and attempt to move the affected control surface
(elevator, rudder, or aileron, as applicable)
3. If the autopilot does not resist your attempt to move the control surface, the shear screw
has failed.
