Confidence Rating: Accident investigation report completed and information captured
During an air show, while conducting aerobatic maneuvers, the airplane continued in a spin to ground impact. According to witnesses, the pilot was performing an aerobatic routine with two other airplanes, known as a "squirrel cage" maneuver. The airplanes would take turns entering the aerobatic box to perform a single choreographed maneuver. The routine card indicated that the pilot was to perform multiple snap rolls when the accident occurred. A video of the pilot's routine was examined with the assistance of members of the International Aerobatic Club. The video showed that the pilot made 3 1/2 snap rolls to the right, and then 2 1/2 spins to the left. It appeared there was no flight control problem and the pilot entered a flat spin. The elevator appeared to be loaded and the pilot never broke the stall prior to impact. The pilot had written a magazine article advocating a specific spin recovery method.
Probable Cause: The pilot's failure to recover from an intentional aerobatic maneuver.
