## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

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.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
