THE STUDENT INITIATED A STRAIGHT-IN PRACTICE AUTOROTATION FROM 550 FEET AGL. THE INSTRUCTOR REPORTED THAT DURING THE DESCENT AIRSPEED AND RPM WERE MAINTAINED WITHIN LIMITS. AT 40 FEET AGL, THE STUDENT INITIATED HIS FLARE, BUT APPLIED AFT CYCLIC SO ABRUPTLY AND WITH SUCH FORCE THAT THE INSTRUCTOR WAS UNABLE TO COUNTERACT THE MOVEMENT. THE HELICOPTER CONTINUED TO DESCEND IN A TAIL-LOW ATTITUDE UNTIL THE STINGER AND TAIL ROTOR STRUCK THE GROUND, BUCKLING THE TAILBOOM. THE INSTRUCTOR REPORTED THAT WINDS AT THE ACCIDENT SITE WERE LIGHT AND VARIABLE.
Probable Cause: the instructor failed to adequately monitor the student pilot's actions and to react within the control margin necessary to successfully initiate a corrective action.
