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.

Substantial damage was sustained after a hard landing during an instructional flight. The flight instructor and student pilot were practicing autorotations. They were practicing multiple straight-in autorotations and then initiated one from a 180-degree turn. During the turning maneuver, the main rotor RPM decayed and the helicopter's decent rate increased; the helicopter subsequently touched down hard and the left skid collapsed and then caused the aircraft to roll and come to a stop after 90 feet.
