The CFI was having the second pilot execute straight in autorotations for familiarization training. The second pilot initiated the autorotation with the rotor in the low range and the CFI instructed the second pilot to reduce collective, which increased their rate of descent. The CFI said that about 18 feet, the second pilot applied 60 percent collective, leveled somewhat, and the nose yawed to the left. The CFI applied full right pedal in an attempt to correct the yaw, but the nose remained yawed to the left approximately 15 degrees. The aircraft hit the ground with the left heel first followed by the nose pitching forward. The CFI stated he applied slight aft cyclic and felt the main rotor contact the tail boom.
Probable Cause: The second pilot misjudging his flare and the delayed remedial actions by the pilot-in-command.
