Flight History
The aircraft departed at 1417 Central Standard Time. Radar track data showed the aircraft climbing to and maintaining 7,600 feet until about 1733 Eastern Standard Time, at which point it was approximately 28–30 miles north of the Knoxville VOR. The aircraft then descended and crossed the Snowbird VOR at about 6,700 feet. Several upward and downward altitude excursions followed. After crossing Snowbird VOR, the aircraft turned south and again exhibited altitude excursions. The final radar contact was at 6,100 feet, about 1 mile from the crash site.
Impact
The aircraft impacted mountainous terrain at approximately 6,000 feet mean sea level (MSL), about 11 miles from the destination. Both occupants were killed.
Meteorological Conditions
At the crash site, meteorological conditions included low clouds and precipitation.
Pilot Toxicological Findings
The pilot's blood alcohol level was 0.4‰.
Official Findings
The National Transportation Safety Board (NTSB) determined the probable cause as the pilot's flight into known adverse weather (including clouds and rain), continued operation under such conditions, inadequate altitude management, and impairment from alcohol, all while operating over mountainous terrain at night.
