## Narrative

DURING APPROACH TO LANDING OFF AIRPORT IN GUSTING WIND CONDITIONS, N190SH EXPERIENCED A HARD LANDING AND ROLL OVER.

ACCORDING TO THE PILOT, THE WINDS WERE GUSTING AND SHIFTING DIRECTIONS. PRIOR TO GROUND CONTACT, THE ROTOR RPM DECAYED. THE PILOT STATED THAT THE ROTOR RPM WAS RECOVERED, AND A RUNNING LANDING WAS PERFORMED. THE AIRCRAFT ROLLED OVER WHEN THE LEFT SKID CONTACTED A DIRT BERM

OF THE FOUR OCCUPANTS, TWO REPORTED MINOR INJURIES. NO POST CRASH FIRE WAS REPORTED.

## 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.
