What happened
The accident occurred just after the aircraft departed in night instrument meteorological conditions (IMC). According to witness accounts, the aircraft climbed to approximately 200 feet above the surrounding trees before entering a descent and disappearing behind a tree line near the departure end of runway 36. Following the impact, the aircraft was completely demolished by fire. Witnesses reported that weather conditions included a low overcast ceiling at about 500 feet and occasional light rain.
The investigation
Examination of the wreckage revealed no mechanical abnormalities or defects in the aircraft that would have contributed to the accident. However, significant administrative and physiological factors were identified during the inquiry. The aircraft was overdue for its required annual inspection. Furthermore, the pilot's medical certificate had expired at the time of the flight.
Findings
Post-accident toxicological testing of the pilot revealed a blood alcohol concentration of 0.142% (142 mg%). This level of impairment is significantly above the legal limit for operating an aircraft and represents a critical factor in the loss of control during the initial climb phase.
