NTSB narrative
THE NEWLY CERTIFICATED PRIVATE PILOT (ROTORCRAFT) WAS MAKING AN OFF AIRPORT HIGH APPROACH TO A PINNACLE WHEN HE EXPERIENCED LOW ROTOR RPM TWICE. THE FIRST TIME HE WAS ABLE TO RECOVER RPM, HOWEVER, HE WAS UNABLE TO RECOVER RPM THE SECOND TIME, AND MADE A HARD LANDING AND ROLLED OVER. EXAMINATION OF THE POWERPLANT AND DRIVE SYSTEM BY AN FAA AIRWORTHINESS INSPECTOR, 'FOUND NO REASON WHY THEY SHOULD NOT FUNCTION NORMALLY.'
Probable cause
FAILURE OF THE PILOT TO MAINTAIN ROTOR RPM, WHICH RESULTED IN A HARD LANDING AND ROLLOVER. A FACTOR RELATED TO THE ACCIDENT WAS THE PILOT'S LACK OF TOTAL HELICOPTER EXPERIENCE.

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.
