NTSB narrative

AT THE END OF A SIGHTSEEING FLIGHT, THE PILOT APPROACHED THE LANDING ZONE WITH A TAIL WIND AND GUSTING WIND CONDITIONS AT 30 KNOTS. APPROXIMATELY 20-30 FEET AGL, A GUST OF WIND CAUGHT THE HELICOPTER WHICH VEERED OFF AND SKIMMED OVER POWER LINES IN THE CLOSE PROXIMITY TO THE LANDING ZONE. POWER WAS APPLIED AND THE HELICOPTER GAINED 20-30 FEET AND CONTINUED ON TO LAND HARD IN THE OPEN FIELD. THERE WERE NO REPORTED MECHANICAL FAILURES OR MALFUNCTIONS WITH THE HELICOPTER AT THE TIME OF THE ACCIDENT.

Probable cause

THE PILOT FAILED TO COMPENSATE FOR THE WIND CONDITIONS.

  • 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.
