Probable cause
Uncommanded rudder movement caused by a contaminant in the engagement valve solenoid that prevented disengagement of the autopilot yaw actuator and cross-connected wiring of the autopilot yaw actuator's main valve solenoids by the operator. Factors contributing to the incident were the lack of proper controls in the solenoid assembly process and the lack of procedures to detect miswired solenoids.
