Accident Summary
An aircraft operating at night in instrument meteorological conditions (IMC) departed controlled flight during cruise and subsequently impacted terrain. The flight was en route when the pilot communicated to air traffic control that the airplane was 'in the soup' and expressed a desire to return to the departure airport. The controller cleared the pilot to climb to 7,000 feet mean sea level (msl) and proceed direct to the departure airport. The pilot acknowledged the clearance, and no further radio transmissions were received from the accident airplane.
Flight Details
The flight was conducted at night with the aircraft operating in IMC. After the pilot's request to return, the controller issued instructions for an altitude change and a direct routing. The pilot confirmed receipt, but subsequent attempts to contact the aircraft were unsuccessful. The aircraft impacted wooded terrain in a near-vertical attitude. The accident site was located in a wooded area, consistent with the controller's last clearance.
Investigation Findings
Examination of the wreckage revealed no pre-impact anomalies with the airframe, powerplant, propeller, or accessories. Investigators found no evidence of mechanical failure or malfunction prior to impact. The aircraft's attitude at impact was near vertical, and the terrain was wooded. The investigation did not identify any pre-existing conditions that would have contributed to the loss of controlled flight.
