While performing a simulated emergency landing during a Part 91 instructional flight, the helicopter touched down hard on open desert terrain, and a main rotor blade impacted the tail boom. The certified flight instructor was teaching his rotorcraft rated private pilot student to land under a simulated emergency condition where the objective was for the student to "land immediately." As the helicopter descended, the low rotor annunciator light illuminated and the corresponding warning horn sounded. Thereafter, the instructor attempted to perform a recovery. According to the instructor, initially both he and his student were simultaneously attempting to take corrective action and the student "had too strong a grip on the throttle for me to overcome." The instructor was handling the controls as the rotorcraft approached and contacted the ground. The instructor stated that despite his efforts, the helicopter touched down hard. No mechanical malfunctions were experienced during the flight.
Probable Cause: The failure of the student pilot to maintain an adequate main rotor rpm and the instructor's failure to maintain control of the aircraft.
