NTSB analysis

The airplane’s fuel tanks were last filled on the day prior to the accident. It was then flown for 1.3 hours before the accident flight, and not refueled. While en route, the airplane experienced a total loss of engine power. The pilot attempted to perform a forced landing to a field, but the airplane’s nose landing gear contacted a power line. The airplane subsequently impacted the ground inverted. From the time of the last fuel service, to the time of the accident, the airplane accrued 6.0 hours of total Hobbs time. Examination of the airplane, including the fuel feed system, by Federal Aviation Administration inspectors revealed no preimpact mechanical anomalies. Only residual and unusable fuel was found in the tanks. According to the airplane owner's manual, the fuel endurance at cruise power setting is 5.9 hours. That figure does not include, engine start, taxi, takeoff, and climb.
