From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported.

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.
