## Analysis

THE PILOT ARRIVED AT THE AIRPORT ABOUT ONE HOUR BEFORE FUEL WAS AVAILABLE. HE ASSUMED THAT HE HAD ENOUGH FUEL REMAINING ON BOARD FOR THE NEXT LEG OF THE FLIGHT BECAUSE THE DURATION WOULD BE ABOUT 10 MINUTES. ABOUT 5 MINUTES INTO THE FLIGHT THE AIRCRAFT'S ENGINE QUIT DUE TO FUEL EXHAUSTION. THE PILOT LANDED THE AIRCRAFT ONTO A FRESHLY PLOWED FIELD AND NOSED OVER DURING LANDING ROLLOUT.
