The NTSB's narrative final · quoted from the NTSB record

THE CFI WAS DEMONSTRATING A HOVERING AUTOROTATION TO THE DUAL STUDENT. BEFORE BEGINNING THE AUTOROTATION, THE CFI FAILED TO ASSURE THE LANDING SURFACE WAS HARD PACKED AND NOT SOFT. WHEN THE HELICOPTER WAS BETWEEN 3- AND 5-FEET SKID HEIGHT ABOVE THE GROUND, THE CFI CLOSED THE THROTTLE AND LANDED STRAIGHT AHEAD. THE HELICOPTER SLID ABOUT 5 FEET BEFORE THE LANDING SKIDS DUG INTO THE SOFT TERRAIN, NOSING THE HELICOPTER DOWN. THE HELICOPTER'S MAIN ROTOR BLADES SEVERED THE TAILBOOM ASSEMBLY.
