According to the pilot, he had topped off the fuel tanks for a trip to Ohio. He stated that he completed a preflight inspection which included draining the fuel tanks and checking for contamination. None was noted. He stated that he was airborne for approximately 3 hours 12 minutes when the engine lost power. His attempts to restart the engine including using the emergency procedures were unsuccessful. He stated that he was 10 miles southwest from the nearest airport, but due to his altitude, 4000 feet msl, he was unable to make a successful landing there.

According to a Federal Aviation Administration (FAA) Safety Inspector, the pilot reported that he topped off the fuel tanks with 28.6 gallons of fuel in Baltimore.

The examination revealed that the right fuel tank was empty, the left tank contained one inch of fuel, and the gascolator was empty. The fuel selector was found selected to the right fuel tank. According to the Cessna Owner's Manual, at an altitude of 2500 feet and a power setting of 21 inches and 2450 rpm, the endurance would be 4.3 hours, and fuel burn of 12.7 gallons per hour, at 5000 feet and a power setting of 21 inches and 2450 rpm the endurance would be 4.2 hours and fuel burn of 13.0 gallons per hour.
