Analysis

Agusta N300CC departed a helipad in front of claremont corp president's residence in south Dartmouth, Massachusetts. As the helicopter was hovering prior to moving forward, the tail rotor blade, s/n 124, failed. The tail rotor assembly and gearbox separated from the helicopter. The helicopter landed hard on the helipad collapsing all three landing gears.
