Event Summary
A pilot reported that shortly after takeoff, the fuel selector was moved from the 'both' position to the 'right' position and was not subsequently repositioned. This resulted in fuel starvation as the aircraft cruised at 16,000 feet about three hours after takeoff.
Emergency Response
The pilot declared an emergency with air traffic control (ATC) and was directed to a nearby airport. The pilot attempted a forced landing but was not successful in reaching the runway. During the landing, the airplane struck a ditch and flipped over, coming to rest in a field near the runway.
Post-Accident Examination
Post-accident examination revealed 35 gallons of fuel in the left tank, no fuel in the right tank, and the fuel selector positioned to 'right.'
Performance and Procedures
According to the pilot's operating handbook (POH), the airplane takes approximately 15 minutes to descend from 16,000 feet to the emergency airport elevation of 535 feet above mean sea level. This descent is at best glide speed (approximately 85 knots indicated airspeed) with the propeller windmilling and flaps and gear up. The POH 'engine failure in flight' procedure directs the pilot to check fuel quantity and place the fuel selector on the fullest tank.
