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.

Pilot reports no adverse indications were noted in the cockpit. The aircraft nose continued to rise with aircraft pulling to the left for an estimated 5 seconds. At about less than 20 knots the pilot reports the left main landing gear collapsed and veered sharply to the left.
