What happened
The aircraft encountered a downdraft while on final approach to a remote strip, resulting in a crash just short of the runway. Following the incident, the individual operating the airplane refused to provide any information concerning the accident. A passenger present during the event stated that they experienced the downdraft immediately prior to the impact.
The investigation
Investigators noted that the pilot had previously held a commercial pilot certificate; however, this certificate was revoked in 1991. Additionally, his airman medical certificate had been denied in 1989, indicating he was not medically qualified to fly at the time of the accident.
Findings
The primary factors contributing to the accident were the downdraft encountered during the approach and the pilot's lack of a current commercial pilot certificate and valid medical certification. The refusal of the pilot to cooperate with investigators limited the ability to determine other potential contributing factors regarding his decision-making or aircraft status prior to the crash.
