Accident Sequence
The pilot reported that just before takeoff, he switched fuel tanks to what he believed was the fullest tank. However, he inadvertently selected the 'OFF' position instead. During takeoff on down-sloping terrain, the engine lost power. According to the pilot, the airplane had just lifted off at the time of the power loss, and he immediately re-landed. He was unable to stop the airplane before it collided with trees at the end of the runway.
Background
The pilot switched fuel tanks prior to takeoff, intending to use the fullest tank. The fuel selector was mistakenly moved to the 'OFF' position, cutting off fuel flow to the engine. The takeoff was conducted on a runway with down-sloping terrain.
Findings
- The engine lost power due to fuel starvation after the pilot inadvertently selected the fuel selector to 'OFF'.
- The airplane lifted off during the takeoff roll but re-landed shortly after the power loss.
- The airplane overran the runway and collided with trees, resulting in damage.
Probable Cause
The pilot inadvertently selected the fuel selector to the 'OFF' position, resulting in a loss of engine power during takeoff.
