NTSB narrative
THE PILOT IN COMMAND STATED THAT HE WAS ON FINAL APPROACH AND AT 125 FEET AGL, HE HEARD THE LOW RPM AUDIO WARNING AND HE IMMEDIATELY ENTERED AN AUTOROTATION BY LOWERING THE COLLECTIVE TO THE FULL DOWN POSITION AND CLOSING THE THROTTLE TO THE FLIGHT IDLE POSITION. HE COMPLETED AN AUTOROTATIONAL LANDING AND HE STATED HIS TOUCHDOWN SPEED WAS TOO FAST, SO HE APPLIED AFT CYCLIC TO STOP THE AIRCRAFT.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
