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.

(.19) On September 29, 1999, at 1445 central daylight time, a Stinson L-5 vintage airplane, N68591, registered to the American airpower heritage flying museum and operated by the confederate air force of midland, Texas, was substantially damaged during a forced landing near Woodward, Arkansas. The private pilot, sole occupant of the airplane, was not injured. Visual meteorological conditions prevailed, and a flight plan was not filed for the 14 code of federal regulations 14 CFR part 91 personal cross-country flight. The flight originated from hutchinson, Kansas, at 1300, with a destination of midland, Texas. The pilot reported to the FAA inspector that during cruise flight the aircraft developed an "extreme" vibration. During the ensuing emergency landing to a county road, the aircraft encountered soft dirt and veered to the right, impacting a ditch. Examination of the aircraft by the FAA inspector revealed that the propeller was damaged, and the right wing was structurally damaged. Further examination of the propeller revealed that one of the propeller blades was missing a metal tip, and the wood beneath this missing metal tip was discolored. (.4)during cruise flight, the airplane developed an 'extreme' vibration. During the ensuing precautionary landing to a dirt road, the aircraft encountered soft dirt and veered to the right, impacting a ditch. Examination of the airplane by the FAA inspector revealed that one of the blades of the wooden propeller was missing its metal tip. (-23)on September 29, 1999, pilot was enroute to childers, TX for his next fuel stop. While cruising at 4,500 feet, immediate vibration started with possible pop noted. The shaking did not stop when pulled power to idle while cruising at 2,300 RPM. Pilot then turned aircraft 90 degrees toward Woodward airport.
