Analysis
The instructor plt (CFI) with only 358 hrs total flt time was demonstrating an autorotation with a power recovery. During the recovery, the CFI failed to fully regain RPM & the helicopter settled to the surface. With a low rotor RPM, there was a loss of tail rotor effectiveness & the helicopter turned to the right. Subsequently, the helicopter touched down with forward movement & right yaw, then rolled over. The CFI reported that the wind was from the north at 10 gusting 15 KTS.
