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.
Narrative: told by ground to taxi, made a right on what he thought was a taxiway to go to runway 31, which got narrow and changed surface conditions, went to turn around, saw low sign just before he hit it - sign was facing the other way and warned to "beware of aircraft".
