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) During a dual training flight the cfi/pic had taken control of the helicopter while the student was donning the IFR hood. During a low hover the aircraft drifted aft and to the right contacting the ground with the aft end of the right skid, bounced and hit a second time harder breaking of the aft 12-14 inches of the skid resulting in the skid being stuck/caught in the ground. The aircraft continued to roll right with a subsequent tail skid strike followed by main rotor contact with the tailboom separating the tail boom followed by the main rotor mast pole/transmission being extracted from the helicopter. The fuselage rolled almost inverted and rolled back to the left coming to rest on its left side. The certified fight instructor and student pilot removed their seat belt/shoulder harnesses and exited the aircraft with no injuries. The pilot reported no problems with aircraft systems or flight controls when questioned during the investigation.
