What happened
During an approach for landing, the pilot determined that visibility was insufficient and initiated a go-around. Witnesses reported that the aircraft touched down with excessive speed and distance along the runway before becoming obscured by fog. Following the touchdown, the aircraft struck a line of trees and continued into a marshland area situated approximately 70 feet below the level of the runway.
Investigation into the aircraft's condition revealed no mechanical failures or engine malfunctions that would have hindered the flight. However, records regarding the pilot's recent activity indicated a period of significant fatigue. On the day preceding the accident, the pilot's duty period began at 0500. Although a nine-hour rest period occurred during the day, it did not include sleep. The pilot arrived home at approximately 2300 and experienced interrupted sleep, waking at 0230 before returning to bed briefly. He eventually rose between 0430 and 0500 to begin his work day at 0530. The pilot's daily routine involved a four-hour round-trip commute, and while he typically requires 6 to 8 hours of nocturnal sleep, his rest prior to the accident was insufficient.
Findings
- The pilot was operating under conditions of inadequate visibility.
- Pilot fatigue resulting from an interrupted rest period and a long commute contributed to the event.
