A witness observed the non-instrument rated private pilot performing a night takeoff. According to the witness, there was light rain falling and the skies were overcast.
Radar Data Analysis
Radar data from the time of the incident showed a primary target that was first detected just east of Wendover, traveling on a southwesterly track. The target then made a turn and flew north, passing over Wendover. Subsequently, it flew towards the northeast, then turned northwest and held this course. The aircraft then executed a 270-degree turn to the left, followed by another left turn of at least 270 degrees. After these maneuvers, it continued on an easterly course until radar contact was lost. No Mode C altitude reporting returns were recorded, meaning the aircraft's altitude was not available from secondary radar.
Accident Site and Wreckage Examination
The accident site was located in mountainous terrain at an elevation of 6,944 feet, near the point where radar contact was lost. Examination of the wreckage indicated that the airplane impacted the terrain in a steep nose-down attitude.
