During a helicopter flight review, the pilot completed three practice autorotations to a landing. After the third landing, the pilot heard a "thud" and no longer had use of the anti-torque pedals. Upon inspection, the tail boom was found to be severed. The cut was consistent with the tip path plane of the main rotor striking the boom, likely from excessive aft cyclic application during the flare. No flight control anomalies were reported by either crewmember.
Probable Cause: The pilot's excessive aft cyclic imput during the flare following an practice autorotation, which resulted in main rotor blade contact with the tail boom.
