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.

During hover and shutdown, the aircraft engine cowling flapped open due to a cowling fastener becoming unlocked. The cowling contacted the main rotor blades causing significant damage to the blades and cowling. Fastener hardware from the cowling was ingested into the running engine causing FOD damage.
