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.

(-23) On approach to Mammoth Lakes airport (mmh) the pilot lowered the landing gear and did not get a green light. He initiated a go around and cycled the gear. He got a green light on the second attempt and he cycled the gear another time to confirm the gear position. On the third cycle he again got a green light. Upon landing roll out the right main gear tried to collapse. The aircraft veered off the right side of the runway and impacted a low snowbank. At that time the nose gear collapsed and the main collapsed completely. The right wing tip tank and wing leading edge sustained damage from the impact with the snowbank. On site investigation found the idler arm for the nose gear/right main gear had sheared at the gear motor allowing the gear to collapse.
