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.

The pilot reported that while back-taxing to reposition for departure, during a left 180 turn, the right landing gear collapsed. Subsequently, the right wing was substantially damaged when it impacted the ground. Post-accident inspection of the right landing gear revealed that the retraction lug on the gear trunnion separated and the retraction bellcrank arm broke, which allowed the gear to collapse and fold inward.
