What happened
A pilot, who was not instrument rated, informed witnesses of his intention to attempt a crossing of the mountains north of the departure airport. The pilot expected to find clear weather in that area before continuing west toward his destination. At the time of departure, witnesses reported weather conditions consisting of a 1200-foot overcast ceiling with good visibility below the clouds.
After flying approximately 35 miles, the aircraft was positioned over the Blue Ridge Mountains. Radar data recorded during the flight showed that the aircraft began changing course approximately 14 times within a 15-minute period, which included several course reversals. During this timeframe, the aircraft climbed from 2100 feet to 7200 feet.
A witness located near the accident site reported that it was raining with visibility of 1000 feet and that the mountain tops were obscured by clouds. This witness heard the aircraft at full power while climbing, followed shortly by a muffled sound and then silence.
The aircraft experienced an inflight breakup, which resulted in the separation of portions of the right wing and the right horizontal stabilizer.
The investigation
An examination of the wreckage was conducted following the accident. The investigation did not reveal evidence of mechanical malfunction.
