Unsafe Condition
Failure of both the main valve and the clutch valve of the autopilot yaw actuator can lead to uncommanded rudder deflections. Crossed electrical connectors between the actuator’s main valves and the flight control computers can cause the autopilot actuator to remain engaged and hydraulically pressurized, providing uncommanded inputs to control surfaces.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Perform a one-time inspection of autopilot systems for proper engagement to check main electro valve electrical connectors of yaw, roll, and pitch actuators. If systems cannot be engaged, conduct a visual inspection of connectors and correct any incorrect installations. Actions must follow specified procedures in Airbus AOT documents.
