Background
The pilot obtained three preflight weather briefings before filing an instrument flight rules (IFR) flight plan using an assumed name. Routine communications were maintained with air traffic control until 2117 Central Standard Time.
Flight
At 2117 CST, the pilot reported that the aircraft was in a thunderstorm cell and expressed a desire to execute a 180-degree turn. The controller cleared the aircraft for a right turn. As the pilot initiated the turn, both radar and communication contact with the aircraft were lost.
Accident
Witnesses on the ground reported hearing several loud engine surges followed by the sound of impact during an intense thunderstorm. The aircraft broke up in flight, scattering wreckage over a path of approximately three-quarters of a mile.
Wreckage and Investigation
Examination of the wreckage revealed no evidence of preexisting material defect or failure. The investigation focused on the circumstances of the loss of control during the thunderstorm encounter.
Probable Cause
The investigation did not determine a probable cause for the accident.
