A pilot with aerobatic experience witnessed the accident airplane maneuvering prior to impact. She reported that the airplane was 'kicking around for the turn-around for a knife-edge spin (identical entry as a hammerhead maneuver). Everything looked normal.' The witness reported the airplane was recovering from this maneuver and initiated a 1/4 roll (down) to the left. The witness reported that, 'The plane got lower and lower, closer to the ground. I could see that there was a last minute positive pitch change. I saw him impact the ground flat.' The pilot was found conscious. The witness reported, 'He was aware of what had happened to him. He explained [to] me on the spot that he G-locked (gray-out) during the pullout of the maneuver... .' The pilot reported that a lack of food and water on the day of the accident, in addition to fatigue, contributed to the accident.
Probable Cause: the pilot experienced GLOC (G induced loss of consciousness) while performing an aerobatic maneuver. Fatigue was a factor.
