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.

Aircraft cleared to land when it crashed on the taxiway. (.4)the pilot reported that the engine lost power, while he was holding short of a taxi way in a hover. The helicopter landed hard on its right skid and rolled over on its right side. Witnesses reported that they observed the helicopter at about 20 feet AGL, when they heard the engine abruptly cease. They then reported seeing the pilot release the collective control with his left hand and apply full aft cyclic with both hands. The helicopter then pitched up to an approximately 45-degree angle while simultaneously falling. The helicopter and the airframe were examined by an FAA airframe and powerplant mechanic, and an FAA airworthiness inspector. No discrepancies were noted. The pilot did not hold a rotorcraft category rating and no evidence was found that he was endorsed for solo privileges in rotorcraft within the previous 90 days.
