Narrative:A videotape of the accident showed the aircraft successfully completing a series of two counter-clockwise aileron rolls, immediately followed by two clockwise snap rolls. During the second run of maneuvers, initiated from an approximate altitude of 100-200 feet AGL, the aircraft recovered from the final snap roll in a 90 degree right-wing down, nose low attitude rather than the wings level attitude of the previous maneuver. One to two seconds later, the aircraft returned to a wings-level attitude having lost approximately half of its available altitude. The nose pitched back to a flat attitude and the aircraft impacted the ground. The aircraft's engine was heard to rev on the tape about a second after the impact.
Probable Cause: The pilot-in-command's delayed recovery from a snap roll. A contributing factor was the low altitude at which the maneuver was initiated.
