Approach and Fuel Selector Movement
As the pilot approached the Rolla, Missouri airport, he switched the fuel tank selector from the right tank to both tanks in preparation for landing. The pilot stated that he did not know which direction he moved the fuel selector valve.
Loss of Engine Power
Shortly after the selector movement, the engine lost power and did not respond to throttle inputs. The pilot executed a forced landing but lacked sufficient altitude to maneuver to the runway. The aircraft impacted approximately 150 yards short of the runway.
Post-Accident Findings
Examination of the aircraft revealed the fuel selector was in the OFF position. The engine was subsequently removed and run in a test cell, where all parameters were within normal limits.
