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.

Minimal altitude was obtained, chose to turn away from power lines and out of the tall corn to a clear area in an attempt to avoid more serious damage and attempted auto-rotation. Landed hard breaking the skid struts. Aircraft pitched forward and the main rotor contacted the ground and tail boom, severing the tail boom. Found loose pneumatic line to the fuel control during on scene investigation.
