Narrative:
THE STUDENT PILOT ALLOWED THE MAIN ROTOR BLADES TO DROP TO A SLOW SPEED WELL BELOW THE GREEN ARC. THE STUDENT PILOT AND THE INSTRUCTOR PILOT ATTEMPTED TO DO A POWER RECOVERY FROM THE ABORTED AUTO-ROTATION MANEUVER BUT THE ENGINE COULD NOT ACCELERATE THE MAIN ROTOR BLADES AT AN ADEQUATE RATE DUE TO THE LOW INERTIA-TYPE BLADES. THE ENGINE DID DRIVE THE BLADES INTO A CONE SHAPE WHICH DID NOT DEVELOP ADEQUATE LIFT TO PREVENT THE HARD TOUCHDOWN LANDING. THE SEPARATED SECTION OF TAIL BOOM AND TAIL ROTOR DRIVE SHAFT WERE FOUND A GREAT DISTANCE FROM THE WRECKAGE DRIVEN BY THE MAIN ROTOR BLADE WHICH WAS DRIVEN BY THE ENGINE UNDER POWER. THE DEFORMED MAIN ROTOR BLADES SHOWED EVIDENCE OF CONEING. THE ONE BLADE TIP CONTACTED THE SOD SURFACE AND BENT DOWNWARD. THE SKID ASSEMBLY SEPARATED DUE TO THE HARD TOUCHDOWN.
