Probable cause

The pilot's attempt to conduct his visual flight into instrument meteorological conditions and the loss of aircraft control by becoming spatial disoriented. The low ceilings and the dark night that existed in the area were factors in the accident.

Analysis

The non-instrument rated pilot took off on a night flight to return to his home under visual flight rules without obtaining a weather briefing or filing a flight plan. Instrument meteorological conditions existed along the route at the time. When the aircraft failed to arrive at its destination the pilot's family reported him overdue. An aerial search along the aircraft's assumed flight route was unsuccessful until an ntap of the aircraft's radar track was obtained from faa's air traffic control center. The search aircraft, using the ntap as a guide, found the aircraft's wreckage in mountainous terrain at the end of the radar plot.
