Narrative:During the first of three aerobatic contest flights, at 4,300 feet agl, the pilot began a 45 degree nose down dive into the 'aerobatic box'. After the 'second wing wag (used to signify the start of aerobatic performance),' the airplane experience a 'high rate' roll to the right. The pilot reported that the right aileron 'jammed.' The right wing's top skin failed and separated from the rear spar. The right wing rear spar buckled, and the leading edge of the aileron was 'jammed' under the trailing edge of the wing in the full up position. The pilot regained control of the airplane, and subsequently landed the airplane on the runway without further incident.
Probable Cause: The failure of the wing skin and the rear spar while performing aerobatics, which resulted in the restricted movement of the aileron.
