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 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.
