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.

On roll-out after landing at approximately 70 knots indicated nose wheel began to vibrate. PIC had to use differential thrust to maintain directional control of aircraft. Subsequently the nose landing gear lower drag leg attach point broke and nose gear collapsed. No preincident damage to nose tire or wheel could be assessed. Reason for severe nose wheel vibration is undetermined at this time.
