Just after takeoff, the aircraft started rolling to the left. As the pilot applied right roll inputs, the aircraft accelerated its roll to the left. As it reached a bank angle of approximately 80 degrees, it descended into the runway surface. The flight was intended as a post-maintenance test flight after installation of a replacement set of wings. A post-accident inspection determined that the ailerons had been misrigged so that they deflected opposite to the inputs of the pilot. Neither the pilot nor the mechanic who accompanied him on the flight detected the aileron reversal during the walk-around inspection or the pre-takeoff flight control test.
Probable Cause: the reverse rigging of the aileron flight control system resulting in aileron deflections opposite that of the pilot's inputs which lead to an uncontrolled descent into the terrain. Factors include the pilot's failure to detect the misrigged ailerons during his pre-takeoff flight control check.
