Robinson R44 II
The pilot was attempting to land the helicopter in a sage brush meadow at an elevation of 6,100 feet msl. While in effective translational lift at 12 to 17 feet agl, the helicopter lost rotor RPM, and the pilot applied throttle in an attempt to increase rotor RPM. Subsequently, the helicopter entered an uncontrolled descent from approximately 10 feet agl, landed hard, and rolled over. One main rotor blade was separated, and the fuselage sustained substantial damage.
