Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot stated that he began the cross-country flight with 4 hours of fuel onboard for the estimated 3-hour flight. While over an airport along the route of flight, he found that the headwind was much stronger than forecast. He calculated that he had 1 hour of fuel remaining and that the remaining flight time to his destination was 30 minutes. As he approached his destination, he was receiving vectors from an air traffic controller when the airplane’s engine sputtered and stopped producing power. The pilot successfully restarted the engine. However, it soon stopped producing power again and would not restart. In the dark night, he performed a forced landing to a small opening in the trees. The first rescue personnel on scene reported that they did not detect the smell of aviation fuel and the pilot reported to rescuers that “he believed he had run out of fuel and that the engine just quit on him.” The airplane’s fuselage was bent upwards immediately behind the cabin area, and both wings were bent and wrinkled.

Factual narrative

The pilot stated that he began the cross-country flight with 4 hours of fuel onboard with an estimated 3 hours en route. During the flight, while over an airport along the route of flight, he found that the headwinds were much stronger than forecast. He calculated that he had 1 hour of fuel remaining, and that the remaining flight time to his destination was 30 minutes. As he approached his destination, he was receiving vectors from an air traffic controller when the airplane’s engine sputtered and stopped producing power. The pilot successfully restarted the engine. However, soon thereafter, it stopped producing power again, and this time it would not restart. In dark night light conditions, he performed a forced landing to a small opening in the trees. The first rescue personnel on scene reported that they did not “smell an obvious odor of aviation fuel.” Additionally, the pilot reported to rescuers that “he believed he had run out of fuel and that the engine just quit on him.” The airplane’s fuselage was bent upwards immediately behind the cabin area, and both wings were bent and wrinkled.
