Accident Details
A commercial pilot was conducting a routine positioning flight under dark night visual meteorological conditions. Security camera footage from the airport showed the airplane taking off normally and initiating a right turn, consistent with the established traffic direction for the runway. The airplane continued the right turn, then entered an increasingly rapid descent and subsequently impacted terrain approximately one mile southwest of the airport. The wreckage distribution was consistent with a high-energy impact.
Investigation Findings
Examination of the airframe and engine revealed no evidence of any preimpact mechanical malfunctions or anomalies that would have precluded normal operation. Autopsy and toxicology testing of the pilot did not reveal any evidence of impairment or incapacitation. Visual meteorological conditions prevailed at the time of the accident; however, the setting Moon was obscured by cloud cover. The airport was located in a remote, sparsely populated high desert terrain, which would have resulted in few visual references to which the pilot could have oriented the airplane. Although the pilot had experience operating in this environment in night conditions and held an instrument rating, the circumstances of the accident are consistent with the known effects of spatial disorientation.
Analysis of Events
The investigation could not determine the initiating event that led to a mismatch between the airplane's perceived and actual attitude. However, the pilot likely experienced a sensory illusion as a result of spatial disorientation, which led to a loss of control.
