The Douglas MD82 experienced a flight control malfunction after takeoff and diverted to Dulles International Airport. The crew reported that they lost the autopilot, there were in-flight kicks on the rudder and the rudder tab was moving uncommanded on the ground. The Yaw Damper Actuator, Digital Flight Guidance Computer, and Dual Axis Accelerometer were removed for further testing. The Yaw Damper Actuator and the Digital Flight Guidance Computer passed testing. The Dual Axis Accelerometer was bench tested using test manual #22-19-01, Rev 1 at the avionics test center. The unit failed an original test and failed a second test after a metal sliver imbedded in the pins was removed.
Probable Cause: The failure of the Dual Axis Accelerometer.
