Analysis

According to a plt/operator statement, the student plt was cleared for a downwind apch to land on 'pad 3.' The student stated that the apch was normal until he slowed to 40 mph & 'made left turn to final approach into a cross wind.' During the turn to final apch, the student attempted to communicate with ATC to request a turn into the wind. During the discussion, the student became distracted. He allow the airspeed to decay & the helicopter began settling with power. Subsequently, the helicopter touched down hard in a tail low attitude & the tail rotor separated. The helicopter then began to rotate & the gear (skid) separated.
