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.
Helicopter landed on a helicopter pad, engine was shut-off and blades slightly rotating when a gust wing came and one blade hit the tail boom. Pilot stopped the rotation of rotor by hand to prevent the other blades hitting the tail boom.
