Flight Details
An instrument-rated pilot decided to conduct a flight under visual flight rules (VFR) to Blacksburg, Virginia. Prior to departure, the pilot was informed by a flight service station that instrument meteorological conditions (IMC) existed at the destination. Despite this advisory, the pilot proceeded with the VFR flight.
About 15 miles west of Blacksburg and 8 miles southwest of Roanoke, the pilot contacted Roanoke Approach Control. During the communication, the pilot reported that he was "stuck" in clouds at an altitude of 2,000 feet mean sea level (MSL). At the same time, witnesses in the area observed an aircraft flying just above treetop level in heavy fog, with an overcast ceiling estimated to be between 100 and 200 feet.
The controller cleared the pilot to climb westward to 5,000 feet. While climbing, the pilot asked for current weather information at Blacksburg. The controller advised that Blacksburg weather was not available. The pilot then requested and received clearance to proceed to Blacksburg on a heading of 240 degrees.
Descent Sequence
The aircraft reached an altitude of 4,600 feet when it abruptly executed a right turn and began descending. The descent continued until the aircraft contacted the ground. Witnesses reported seeing the aircraft descend from a low overcast in a nose-down attitude, with the engine operating at high power.
Investigation Findings
An examination of the aircraft revealed no evidence of mechanical malfunction. Additionally, toxicological testing and other checks found no evidence of pilot impairment or incapacitation.
