What happened
While en route to his destination, a pilot not rated for instrument flight encountered instrument meteorological conditions (IMC). Prior to the flight, the pilot had received three separate weather briefings from a flight service station, which indicated a stationary front with high clouds along the intended route.
Air traffic control radar tracked the aircraft ascending through 5,000 feet. Upon reaching an altitude of 10,000 feet, the aircraft began a rapid descent characterized by a tight right turn. The final radar contact occurred when the aircraft was at 7,500 feet. A witness observed an aircraft emerging from the clouds and diving at a very high rate of speed. Following the event, debris from the aircraft was located scattered across an area spanning up to a half-mile from the primary wreckage site.
Findings
The investigation determined that the pilot experienced spatial disorientation after entering IMC. The accident resulted in no fatalities reported in the source text, though the impact involved a high-speed dive.
