Analysis
The student was a rated single eng, multiengine, land plt, but did not have a helicopter rating. During a dual instructional flt, he had just completed the final phase of an autorotation & the skids were on the ground, when he abruptly pulled the collective pitch to the full up position. According to his instructor (CFI), the helicopter lifted off the ground, then the student pulled the cyclic full aft & to the right & froze on the controls. The CFI reported that he overpowered the cyclic to level the helicopter & waited for the impact. The main rotor blades, tail rotor assembly, tail boom, cross tubes & skids were damaged.
