The NTSB's narrative final · quoted from the NTSB record
Witnesses reported the airplane was circling a home at an altitude between 700 and 1,000 feet above the ground. One witness said the airplane was losing altitude while it was maneuvering. Another witness said the airplane was '...flying at a slow rate of speed, making [an] approximate 30-degree turn. The engine was running when the right wing stalled, turning the airplane upside down. The plane then nose dived to the ground.' The toxicological report reported 112 (mg/dL, mg/hg) of Ethanol was detected in the pilot's urine sample. The report stated that 84 (mg/dL, mg/hg) of ethanol was detected in the vitreous fluids examined. No mechanical anomalies were found with the engine, airframe or control system that would prevent normal flight.
