Nope.
Rob. Me thinks you know very little about this accident. I have heard various reports from people very close to the people on the ground and after reading the entire report, I don't agree with your theory. To the ATSB this is just another private mustering accident, fact is they wouldnt't know their earhole from their a***hole and will go with the theory that takes the least work. The pilot needs to accept the consequences of his actions and understandably he has taken it very badly thus far. Unfortunately the majority of private mustering pilots (although he had a CPL) have very little professionalism and it really was a matter of time until something like this happened. Lets hope lessons are learnt. Stick to your Yak.
