What happened
While conducting a cross-country flight under instrument flight rules (IFR), the pilot was instructed by air traffic control to begin a descent and execute a heading change to initiate the approach. Although the pilot acknowledged these instructions, the controller observed approximately one minute later that the aircraft was no longer following the assigned heading. When questioned about the deviation, the pilot reported that the aircraft was in a spin. Following this final transmission, all communication ceased.
The wreckage was later found within steep, mountainous terrain. A witness near the crash site reported hearing an aircraft in a dive, though visibility was obscured by heavy cloud cover. The witness noted that the sound of the engine fluctuated in volume multiple times during the descent. There were no survivors in the accident.
Findings
Investigation of the aircraft components and engines showed no mechanical failures that would have prevented the plane from operating normally. Weather analysis confirmed widespread cloud cover was present during the flight. It is believed that the pilot lost control of the aircraft after entering the clouds. The observed fluctuations in engine noise likely occurred as the pilot attempted to recover from the uncontrolled spin.
