What happened
Several witnesses observed the aircraft operating at extremely low altitudes, reportedly flying below tree-top level immediately prior to the accident. During this low-altitude maneuvering, witnesses noted that the engine noise changed character, sounding as though it had cut out. Shortly after these observations, the aircraft impacted the ground while in a steep left bank.
The investigation
A post-accident inspection of the wreckage was conducted to determine the mechanical status of the aircraft prior to impact. This examination revealed no evidence of any pre-impact malfunction or failure of the aircraft systems that would account for the observed behavior.
Findings
The primary factor identified in this accident was the pilot's impairment. A toxicology report performed on the pilot indicated a blood alcohol level of 0.248%, which is significantly above the legal limit for operating an aircraft. This high level of intoxication likely contributed to the impaired judgment and motor skills required to perform low-altitude maneuvers safely.
Safety message
Operating an aircraft under the influence of alcohol poses a severe risk to aviation safety. The pilot's blood alcohol concentration was well above permissible limits, highlighting the critical importance of sobriety in flight operations.
