I note now that CASA are 'instructing' operators to directly CC any report made to the ATSB to them
That is because the ASTB are sick of CASA either doing nothing or simply 'baying for operator blood' and wanting to be strictly punitive (just ask Dr Alleck about his stupid theories). So when you have a Regulator wanting to roger you every time you try to do the correct thing and report your mistake you end up with a non-reporting culture. However there is no obligation to CC CASA on some specific ATSB matters, so for your own protection tell em to get f*cked as they are not interested in increasing safety, well not ina fair and just fashion anyway.
The ATSB are also 'sectioning' Operators almost daily now so that the operator is obligated under law to report all details of the incident without having to pass it directly on to CASA and get rogered by CASA. Smart move by the ATSB but a sad indictment of how disconnected and retarded CASA has become.
