Witnesses reported that the airplane was maneuvering when there was a loud bang. They reported that the airplane's right wing had failed, and the fuselage was distorted before the aircraft crashed. Aircraft examination revealed that the airplane's horizontal tail had failed due to a positive G maneuver, and the wings and wing struts had failed due to a negative G maneuver. Eight days previous to the accident the pilot had flown a Waco airplane in Hawaii doing aerobatics.
Probable Cause: The pilot's maneuvers which exceeded the design stress limits of the airplane and resulted in structural overload of the horizontal tail followed by a structural overload of the wings.
