What happened
A flight involving the pilot and two passengers began as an instrument flight rules cross-country trip under night instrument meteorological conditions. During the initial climb, the pilot notified air traffic control that the aircraft type was encountering light rime icing and freezing drizzle between 6,500 and 8,000 feet MSL. After being cleared to climb to FL230, the pilot reported a malfunction with the deicing equipment at approximately 11,600 feet MSL and requested a return to the departure airport.
While descending, the pilot informed the controller that a circuit breaker had tripped and could not be reset. As the aircraft reached 4,700 feet MSL, the pilot reported experiencing issues with the flight instruments. Following instructions to maintain 5,000 feet, the pilot stated he was "pulling up," after which all radio contact ceased. Radar data indicated the flight path transitioned from a straight track to a descending right turn with a decreasing radius before the track terminated. The aircraft struck the terrain in a right-wing-low attitude, resulting in a fragmented wreckage field spanning approximately 570 feet.
Findings
Investigation of the wreckage, including the engines and flight control surfaces, revealed no evidence of pre-impact mechanical anomalies. While maintenance records showed previous repairs to propeller and surface deice circuit breakers, the extent of the impact damage prevented a specific assessment of the deicing systems. Radar and radio data confirmed the electrical system was functioning prior to the crash. It was determined that the pilot's attempts to troubleshoot the circuit breakers and communicate with air traffic control likely caused spatial disorientation due to distractions while flying in IMC.
