The helicopter sure seemed out of control when it hit the ground. ATSB wrote: "the helicopter impacted the ground at approximately 80° right angle of bank and 60° nose down pitch". Something worrying is that the report indicated a relative contacted the pilot by (mobile) phone at 15:47 to check progress and all seemed well. But by around 15:56 (9 minutes later) the so far unexplained turn was commenced. The report doesn't mention any communications between the pilot and ATC (indicating any sort of distress).
