NTSB narrative
The non-instrument-rated pilot was conducting the accident flight under visual flight rules (VFR) without a flight plan in dark night conditions. Before the flight, the pilot obtained several weather briefings indicating that instrument meteorological conditions prevailed along his route of flight. Postaccident review of weather and radar data indicated that the airplane descended into instrument meteorological conditions near the destination airport. Based on the wreckage distribution, which was consistent with a high-speed impact, and the adverse weather conditions present at the time of the accident, it is likely that the pilot experienced spatial disorientation and lost control of the airplane. Federal Aviation Administration guidance indicated that spatial disorientation can occur when there is no natural horizon or surface reference, such as night flight in sparsely populated areas similar to that of the accident area and in instrument conditions. A postaccident examination of the airplane revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
Probable cause
The non-instrument-rated pilot's decision to fly into known instrument meteorological conditions, which resulted in the pilot's spatial disorientation and loss of airplane control.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2012-01-22.
