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.
