Overview
Radar data and a witness account document the flight path of an aircraft that ended in a collision with terrain. The aircraft was observed in visual conditions and was reported to appear fast at a high altitude.
Maneuver and Descent
According to radar data, the aircraft completed a figure-eight maneuver at approximately 3,000 feet above ground level (AGL). During the maneuver, it maintained an estimated airspeed of 140 knots and a bank angle of about 40 degrees. After leveling out at the completion of the figure-eight, the radar track showed a period of level flight before a rapid descent began.
Witness Account
A witness reported observing the aircraft flying at high altitude under visual conditions. The witness noted that the aircraft "appeared fast." The aircraft performed a wide, shallow left turn, then reversed direction. The witness then saw the nose gradually lower, and the airplane eventually came straight down and began to spin. The aircraft disappeared from view behind hilly terrain, and the witness did not see the impact.
Wreckage Examination
Post-accident examination of the wreckage revealed that the aircraft struck the terrain in a slight nose-down attitude. The impact site was located in a gully, with the aircraft at an approximate 30-degree bank angle at collision. After impact, the aircraft slid downhill to the right and came to rest with the fuselage upright. The empennage was twisted to the right and inverted. Investigators found no evidence indicating a mechanical failure or malfunction.
