From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) The following narrative was developed through interviews and statements from the pilot, witnesses, and an on-scene investigation conducted by personnel of the allegheny flight standards office, EA03. The pilot, Mr. John w. benford, holder of private pilot certificate #163324691, departed the Somerset County Airport, 2G9, Somerset, PA, on a local IFR training flight under vmv. After a preflight, he took off at approximately 1400L on August 10, 2000. At approximately 5 miles from the Somerset airport, during a second localizer approach, the pilot stated that the engine began to run rough. At that point in time, the pilot said he was airborne for about 40 minutes. He said he switched fuel tanks which only helped a little. The pilot added that he attempted to continued to switch fuel tanks but could not keep the engine running. The engine stopped and the aircraft descended until it impacted the ground in a schoolyard adjacent to the airport property at 1450 l. after the aircraft hit the ground, it slid approximately 65 feet until it impacted the airport perimeter fence and came to a stop. An on-scene investigation found no fuel in the fuel system from the filter to the flow divider. Removal of the fuel tank inspection panels on the wing revealed approximately one quart of fuel in the wings. There was no other evidence of fuel leakage on the wings, and there was continuity established in the fuel system. The pilot stated that during preflight, he thought there were approximatley 40 gallons of fuel on board.
