Discrepancy: Yoke kicks when Autopilot engages
Possible Fix: Adjust the autopilot actuator input rod to the affected flight control surface.
Tip: Adjust both Autopilot system actuator rods for that control surface even if only one is kicking. Adjusting one rod may effect the adjustment of the other.
Reason/Explanation: It is in the MM to adjust the rod when you replace the actuator. If this adjustment if off, after the actuator sync’s the second soleniod engages it to the surface, and will kick if it is off.
