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.

Description: while conducting CFR 133 operations the pilot stated he landed the aircraft into the wind on flat ground to reset a cone that had been blown over by the strong winds of the day before. The pilot stated that he retarded the throttle to idle, frictioned the cyclic control, exited the aircraft and walked 100' to the bag. The pilot stated he heard the rotors begin to beat on the tail boom and ran back and pushed the cyclic forward from full aft. The pilot stated he had apparently not frictioned the control quite enough for the wind conditions , gusts to 24KTS. The blades contacted the top of the tail boom area striking the tail rotor drive shaft. The shaft was severed and separated from aircraft and found on the ground near the aircraft.
