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.

After main gear touchdown, the left main landing gear failed causing the left wing to drop to the runway. The left engine contacted runway and subsequently the left engine fire indication/warning activated. The aircraft remained on the runway, and came to rest on the runway surface with no fire. The evacuation of the aircraft proceeded out the right side and there were no reported passenger injuries and only one minor fa injury reported to be small friction burn on the hand from going down slide. Airport emergency personnel responded.

Preliminary indications reveal an area of corrosion on the main landing gear cylinder outer housing that may have formed during the last overhaul re-chroming process. Metallurgical analysis remains ongoing.
