NTSB narrative
THE PLT STATED THAT AFTER MAKING AN APCH FOR LNDG INTO THE WIND, HE FLEW THE HELICOPTER TO A 6 FT HOVER. HE INITIATED A LEFT PEDAL TURN TO A HEADING OF APRX 220 DEG. ON THIS HEADING, THE WIND WAS FROM THE RIGHT REAR. THE PLT RPRTD THERE WAS AN ABRUPT PITCH-DOWN OF THE HELICOPTER'S NOSE. HE APPLIED FULL AFT CYCLIC & COLLECTIVE PITCH, FOLLOWED BY RIGHT PEDAL IN AN ATTEMPT TO TURN THE HELICOPTER INTO THE WIND. SUBSEQUENTLY, THE HELICOPTER HIT THE GROUND WITH THE RIGHT SKID IN A NOSE LOW ATTITUDE & WAS DAMAGED. THE PLT ESTIMATED THE WIND WAS FROM 330 DEG AT 14 GUSTING 25 KTS. ABOUT 8 MI AWAY AT PALM BEACH INTL ARPT, THE WIND WAS FROM 360 DEG AT 17 KTS. THE HELICOPTER HAD BEEN LOADED TO ITS MAXIMUM ALLOWABLE MOMENT ARM.
Probable cause
THE PILOT'S INADEQUATE COMPENSATION FOR WIND CONDITIONS. FACTORS RELATED TO THE ACCIDENT WERE: THE UNFAVORABLE AND GUSTY 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.
