I think most here would think it more likely that the failure in this tragic accident will be with the pilot, not the aircraft. Clearly we don't know the cause, but I do find this sort of official comment maddening:
"the LCSO reported the aircraft experienced an undetermined failure causing the crash"
It is unfairly damaging to the reputation of helicopters, Robinson and even maintenance organisations when such ignorant comments are made - there is no way that could yet be known. And course it inevitably gets repeated in other media.
