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 March 7, 2003, about 0710 mountain standard time, a Stinson 108-1, N8344K, nosed over during a forced landing in a field near Eloy, Arizona. The forced landing was precipitated by a loss of engine power during cruise. The pilot/owner was operating the airplane under the provisions of 14 CFR part 91. The private pilot, and sole occupant, sustained minor injuries. The airplane sustained substantial damage. The personal cross-country flight departed ryan field, tucson, Arizona, about 0650, en route to casa grande, Arizona. Day visual meteorological conditions prevailed, and no flight plan had been filed. The primary wreckage was located at 32 degrees 36 minutes north latitude and 111 degrees 31 minutes west longitude. The pilot was interviewed at the scene and told investigators that she was flying at 4,500 feet mean sea level when the engine started to make loud noises. She heard a bang, followed by a total loss of power. The pilot made a forced landing on a plowed field. During rollout, the landing gear caught in the soft dirt, which caused the airplane to nose over. The airplane came to rest in an inverted position. Investigators examined the wreckage at air transport, phoenix, Arizona, on March 8, 2003. The engine was examined and the number 3 and 4 cylinders were badly damaged. The number 4 cylinder exhaust valve had fractured at the stem and was missing.
