Factual narrative
THE PRIVATE PILOT WAS FLYING FIVE PASSENGERS ON A ROUND TRIP CROSS COUNTRY FLIGHT. ACCORDING TO THE PASSENGERS, THEY PAID THE PILOT FOR THE FLIGHT. THE PILOT SAID HE TOOK OFF WITH WHAT HE ESTIMATED WAS 64 GALLONS OF FUEL. TWO HOURS AND TWENTY FIVE MINUTES LATER, HE REPORTED THAT THE PLANE WAS OUT OF FUEL, AND HE ATTEMPTED AN ENGINE OUT LANDING TO RUNWAY 33. THE PLANE LANDED 400 FEET SHORT OF THE RUNWAY, STRUCK A FENCE, SHEARED THE NOSE GEAR, AND NOSED OVER. THE PLANE CAME TO REST INVERTED 40 YARDS SHORT OF THE RUNWAY. BOTH WINGS, THE CABIN AND FUSELAGE WERE SUBSTANTIALLY DAMAGED. THE RESCUE PERSONNEL AND LAW OFFICERS ON THE SCENE REPORTED THE TANKS WERE EMPTY AND NO FUEL SPILL WAS FOUND AT THE ACCIDENT SCENE. THE INVESTIGATION FOUND NO FUEL IN THE ENGINE SYSTEM, AND COULD FIND NO EVIDENCE TO EXPLAIN ANY INCREASED FUEL USAGE. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
