NTSB narrative
WINDS WERE GUSTING TO 35 KNOTS AGAINST THE LEFT REAR OF THE HELICOPTER. FOLLOWING THE PREFLIGHT, THE PILOT PLANNED A 180 DEGREE PIVOT PRIOR TO HOVERING. AS THE PILOT INITIATED THE PIVOT, THE FRONT OF THE HELICOPTER ROTATED TO THE LEFT 70 DEGREES, PITCHED UP, ROLLED TO THE RIGHT AND CAME TO REST ON THE HELIPAD. THE HELICOPTER TIEDOWN WAS STILL ATTACHED AT THE RIGHT REAR SKID.
Probable cause
THE PILOT'S FAILURE TO REMOVE THE TIEDOOWN DURING THE PREFLIGHT AND AN INADEQUATE PREFLIGHT.

Source notes (4)
- 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.
