The pilot was performing a normal approach when he noticed a slight "rotor droop." The tail of the helicopter then "snapped left," the helicopter began rotating clockwise, and the LOW ROTOR RPM warning activated. The pilot said he pushed the cyclic forward and applied "up collective" in an attempt to slow the descent rate. He said he was unable to apply further forward cyclic input due to other aircraft operating in the vicinity. The helicopter impacted the ramp in an upright attitude collapsing the right skid further than the left The tail rotor struck the ground and the tail boom cracked.
Probable Cause: the pilot's failure to maintain adequate rotor rpm which resulted in a loss of control and an uncontrolled descent.
