Accident Overview
During a cross-country flight from Wisconsin to California and return, a low-experienced private pilot who was not instrument rated encountered instrument meteorological conditions (IMC). The aircraft subsequently impacted flat, snow-covered terrain, which resulted in its destruction. One passenger was killed in the accident, and three other occupants sustained injuries.
Investigation Findings
Examination of the wreckage revealed no evidence of any pre-accident malfunction or failure of the aircraft or its engines. The investigation identified the following findings:
- The flight occurred during night conditions.
- The pilot made improper in-flight planning and decisions.
- The pilot had inadequate transition or upgrade training.
- The flight encountered turbulence.
- The pilot initiated flight into known adverse weather.
- The pilot lacked familiarity with the aircraft.
- The pilot continued visual flight rules (VFR) flight into IMC.
- The pilot inadvertently became lost or disoriented.
- During descent, the pilot lost control of the aircraft, with airspeed and altitude becoming uncontrolled.
- The aircraft collided with terrain in an uncontrolled descent.
- The terrain was an open field covered with snow.
Probable Cause
The probable cause of this accident was the non-instrument-rated pilot's improper in-flight planning and decision-making, inadequate transition/upgrade training, flight into known adverse weather, lack of familiarity with the aircraft, continued VFR flight into IMC, and inadvertent disorientation, which led to a loss of control during descent with uncontrolled airspeed and altitude, resulting in collision with terrain.
