Primary finding
Probable cause
A loss of engine power during takeoff due to fuel starvation as a result of the pilot’s selection of an empty fuel tank prior to departure.
Investigator assessment
Analysis narrative
The engine lost power after takeoff and the pilot landed in a nearby field, where both wings collided with fence posts. The pilot reported that the left fuel tank was about 1/4 full and the right fuel tank was empty. He had the left fuel tank selected during start up and taxi. As he did his pre-takeoff engine run-up checks, he switched fuel tanks per his normal procedure but did not return the selector valve to the left tank prior to departure. Both wings sustained substantial damage during the accident sequence.
