Incident Overview
During a cross-country flight, the aircraft traversed high mountainous terrain where areas of rain and snow showers had been reported. Airman's Meteorological Information (AIRMET) advisories had been issued for turbulence, mountain obscuration, and icing conditions. Satellite imagery revealed the presence of standing lenticular clouds in the area.
Flight Details
The flight did not obtain a weather briefing prior to departure, and no flight plan was filed. No voice communications were received from the aircraft, and the FAA was not providing any in-flight services for the flight.
Radar and Trajectory Analysis
Radar data indicated that the airplane executed several maneuvering turns followed by a rapid descent before radar contact was lost. Subsequently, the airplane experienced an in-flight breakup, with wreckage scattered over an area approximately three-quarters of a mile in length. A trajectory study determined that the location of the separated components was consistent with a breakup altitude of 14,000 feet.
