It was an A star...dont know if it was B2 or B3. It happened near the approach end of 22L I believe. Fox 10 was on the scene first because they were actually at the US60 about 5 miles south of FFZ and heard the call...they begged and pleaded but the Falcon controllers wouldnt let anyone into the airspace until they had landed (crashed). The helicopter reportedly started spinning around about 35 feet AGL and hit hard collapsing one side of the skids. One nurse escaped immediately while two crew members were temporarly trapped until they could get the blades stopped.
