Aircraft involved

Probable cause & findings

Fuel starvation due to the pilot’s incorrect movement of the fuel selector valve to OFF, which resulted in a loss of engine power.

Factual narrative

The pilot reported they were on a local flight and, while attempting to balance the fuel load, move the fuel selector valve from the “left” main tank position to the “right” position, the airplane subsequently lost engine power. The pilot was not able to restart the engine and performed a precautionary landing onto a road. Shortly after touchdown, the airplane veered off the road and into a ditch. The wings and engine truss sustained substantial damage. Postaccident examination of the airplane revealed that fuel was present in the fuel tanks and that the fuel selector valve positions available were WING TANKS (9 o’clock position), MAIN TANK (12 o’clock position), and OFF (3 o’clock position). The pilot reported that he moved the fuel selector valve from the “left” tank, which was actually the WING TANKS position, to the “right” tank, which was actually the OFF position.
