During an airshow, the pilot was performing a reverse half-Cuban eight. He flew down the runway at approximately 400 feet above ground level (agl) and pulled up using a 45-degree nose up attitude. At approximately 2,500 feet agl, the pilot rolled the aircraft inverted and pulled to a vertical nose down attitude. He failed to recover from the dive and the aircraft struck the ground in a 5-degree nose down attitude with a high sink rate. Ground speed at the time of impact was approximately 485 knots. According to persons at the airshow who are aerobatics pilots, the maneuver being performed by this aircraft should be started no lower than 4,000 feet agl, and part of the altitude gain should be used to bleed off excess airspeed. Videos of the performance depict the speed brakes deployed, the vertical stabilizer moving up and down, and the leading edge devices deployed while the aircraft was in the dive.
Probable Cause: Inadequate planning and decision making by the pilot in starting the aerobatic maneuver at an insufficient altitude to successfully complete the maneuver.
