NTSB narrative
THE PLT RPRTD THAT WHILE HE WAS MAKING A TURN-AROUND OVER TREES AFTER THE 1ST SWATH RUN, THE HELICOPTER ENCTRD A SUDDEN WIND CHANGE. HE STATED THAT THE WIND COND WAS FROM A CUMULUS BUILDUP WHICH PUT HIM IN A TAILWIND SITUATION. AS HE COMPLETED HIS TURN WITH NEAR ZERO AIRSPEED, THE HELICOPTER BGN TO SETTLE WITH POWER. THE PLT TRIED TO FLY OUT OF THE SITUATION, BUT THE TAIL ROTOR STRUCK A TREE LIMB & SEPARATED, CAUSING THE HELICOPTER TO SPIN. THE PLT ROLLED OFF THE THROTTLE IN AN ATMT TO MAKE AN AUTOROTATION & THE HELICOPTER TOUCHED DOWN HARD.

- 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.
