Before we play the normal "pile on Dick" game. I think the point he is making is that there is a pre-existing directive from the Minister about use of approach radar in the airspace of the accident. If there is a Ministerial directive as Dick asserts and if AsA has not complied with this directive then subsequently there has been an accident that could have been avoided if AsA complied with the Minister's directive, then Dick is absolutely correct in suggesting that the ATSB has been deficient in its investigation.
