NTSB narrative

THE HELICOPTER WAS ON AN FAA CERTIFICATION TEST FLT WITH A PART-TIME COMPANY EMPLOYEE IN THE LEFT SEAT AS PILOT- IN-COMMAND (PIC). AN FAA TEST PLT WAS IN THE RIGHT SEAT. THE PURPOSE OF THE FLT WAS TO ESTABLISH NEW DATA FOR THE HELICOPTER'S HEIGHT-VELOCITY (HV) CURVE. THE PIC STATED THAT ALL POINTS ALONG THE CURVE HAD BEEN SUCCESSFULLY DEMONSTRATED ON AN EARLIER DATE. AFTER A NUMBER OF AUTOROTATIONS, THE PIC SUCCESSFULLY DEMONSTRATED A SPECIFIC POINT AT 100 FT & 48 KTS. THE FAA PLT THEN TOOK THE CONTROLS & ATTEMPTED TO DUPLICATE THE POINT IN QUESTIONS. THE FLARE FOR THE LANDING DID NOT ARREST THE DESCENT. SUBSEQUENTLY, THE HELICOPTER LANDED HARD & THE MAIN ROTOR SERVED THE TAIL BOOM. BOTH PLTS ADMITTED THAT THEY DID NOT CLEARLY DEFINE THEIR INDIVIDUAL RESPONSIBILITIES PRIOR TO THE FLT.

  • 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.
  • API snapshot SHA-256: 37fa494d29f1780349adec515a42160d995a8c3bbc2f82410604fd420cf9e9e2; retrieved 2026-09-23T22:16:49.578Z.
