Probable cause

Excessive wear on the bushings and the right aileron inboard and outboard power control unit output link resulting in the upward movement of the right aileron during cruise climb, uncommanded right roll. A factor in the accident was inadequate maintenance inspection procedure by the aircraft manufacture for the aileron system backlash check performed by the operator. The inspection procedure did not require the operator to record the tolerance found during the backlash check.
