The CFI stated he was asking the rated pilot questions as the rated pilot was making a steep approach at 300 feet and about 35 knots airspeed. He asked the pilot receiving instruction if he could roll the throttle off. The rated pilot replied, 'roll the throttle off' and immediately rolled the throttle off. The CFI noticed an immediate drop in rotor rpm, and took over the flight controls with the helicopter in a vertical rate of descent. He lowered the collective pitch in an attempt to regain rotor rpm, but did not apply forward cyclic to increase airspeed due to low altitude. The helicopter collided with the sod area hard, and rolled over onto its left side.
Probable Cause: The CFI's inadequate supervision and poor communication which led the rated student pilot to roll the throttle off, and the CFI's subsequent failure to apply forward cyclic to increase airspeed which resulted in the subsequent hard landing and roll over.
