The NTSB's narrative final · quoted from the NTSB record
ACCORDING TO THE STATEMENTS BY BOTH PILOTS, THE PURPOSE OF THE FLIGHT WAS TO CHECK OUT A NEW FLIGHT INSTRUCTOR ON THE HELICOPTER TYPE. WHILE PRACTICING AN AUTO ROTATION TO TOUCHDOWN, THE NEW FLIGHT INSTRUCTOR OVER ROTATED DURING THE FLARE AND SCRAPED THE TAIL SKID ON THE PAVEMENT. IN HIS STATEMENT, THE NEW FLIGHT INSTRUCTOR SAID HE THEN PULLED UP ON THE COLLECTIVE AND THE HELICOPTER BALLOONED UPWARD TO ABOUT 15 FEET AGL. THE MAIN ROTOR SPEED WAS LOW, AND, AS A RESULT, THE HELICOPTER LANDED HARD. THE MAIN ROTOR THEN FLEXED DOWNWARD AND SEVERED THE TAIL BOOM. THE FLIGHT INSTRUCTOR WHO WAS CHECKING OUT THE NEW PILOT SAID HE HAD HIS HANDS ON THE CONTROLS DURING THE MANEUVER BUT WAS 'UNABLE TO CORRECT FOR THE UNEXPECTED INPUT BY [THE STUDENT]' IN TIME TO PREVENT THE BALLOON AND THE SUBSEQUENT HARD LANDING.
