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) After departing great falls (gtf), Montana, for poplar (42S), Montana, the pilot received a weather briefing from gtf flight service station for light to moderate turbulence below 15,000 feet. The blaine county undersheriff reported strong, gusty winds in the Chinook (S71), Montana, area at the time of the accident. The survivor stated the engine quit. The aircraft, N30921, contacted the top of a cottonwood tree while maneuvering for an emergency landing on a dirt county road. It contacted the hard-packed road 98 feet from the tree that was hit. The aircraft was in an approximate 40 degree nose-down angle when the propeller spinner contacted the road. The aircraft traveled 10 feet from impact marks before coming to rest. The cabin, cockpit, and inboard portions of both wings were consumed by a post-crash fire. See attached drawings for details.
