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.

Airman attempted landing in private property field and subsequent to touchdown, applied brakes too quickly. As the aircraft began to roll to a stop it nosed over, ending up inverted on the ground. Aircraft had "tundra" tires installed. Field was recently cut alfalfa, with the remainder still several inches in length. Airman was surprised with how quickly the aircraft brakes became effective upon landing, and surmised after the fact that the tundra tires may have "grabbed" the remaining alfalfa material during braking more than he was anticipating.
