Fuel Selector Position
A member of the National Navion Association commented that if a pilot attempts a takeoff with the fuel selector positioned on one of the tip tanks, the engine will quit soon after takeoff. The Pilot's Operating Handbook (POH) for the aircraft directs that takeoffs be conducted with the fuel selector on a main fuel tank. Following the incident, the fuel selector was found positioned on the right main fuel tank.
Engine Examination
Post-accident examination of the engine revealed no abnormalities that would have prevented normal operation. The engine was capable of producing power as expected.
Additional Context
The forced landing was necessitated by the loss of engine power. The impact with plant roots during the landing roll occurred after touchdown. No further information about the aircraft type, registration, location, or occupants was provided.
