NTSB Narrative Summary Released at Completion of Accident
The pilot, who owned the airplane and was an experienced aerobatic pilot, stated that he had taken off, accelerated along the runway, then pitched up to about 30 degrees and had climbed out to about 500 feet above ground level. He then pitched over to level to accelerate and initiated a turn to the right, with the intent of climbing out to an aerobatic practice box. He stated that when he pitched over, he felt negative 'G' loading, and the airplane appeared to perform a portion of an outside snap roll, with the right wing dropping and nose going down violently. The airplane then pointed down very steeply about 90 degrees off heading to the right. He stated that an attempt was made to pull out, but the airplane was in a high speed stalled condition, so he pushed the throttle full open and pushed the nose straight down to relieve the stalled condition and again attempted a recovery. This time, the airplane was not stalled and he was able to initiate a pull out. During the recovery attempt, the airplane impacted a road, slightly tail low, and the propeller struck the ground, leaving several prop strikes in the asphalt. The airplane bounced off the road at a 45 degree angle, then impacted a power pole. The pilot noted at the G meter was pegged at +13 G and -5 G. No preexisting mechanical anomalies that could have resulted in loss of control were found by FAA inspectors who inspected the wreckage.
NTSB Probable Cause Narrative
