## 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.

## 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.

## Factual narrative

The engine lost power after takeoff, and the pilot landed in a nearby field. Both wings collided with fence posts. The pilot reported to a Federal Aviation Administration inspector that the left fuel tank was about 1/4-full, and the right fuel tank was empty. He had the left fuel tank selected on start up and taxi. As he did his pretakeoff run up checks, he switched fuel tanks per his normal procedure. He did not return the selector valve to the left tank prior to departure.
