I don't think it is fair to say that CASA don't care about safety but it is apparent to me that they know nothing of the science of risk management. CASA seems to be predicated on nobody flying is safe aviation. They need a rejig of their reason for being. It should be to maximise access to aviation with balanced risks. Safe is always going to be a relative thing if there is activity. Sometimes even doing nothing is unsafe.
So, paramount in their thinking needs to be balanced risk not absolute safety. The FAA seem to have a grasp of this concept by introducing the DL medical and, after more than ten years of experience they are so happy with it that they are seriously considering extending the DL medical to more non-commercial aviators.
The CASA approach is to see what the yanks have done and then implement the CASA version of a DL medical that is a joke and nothing like the FAA put in place and has no basis in prudent risk management.
In my judgement, McCormick has been the worst thing ever to happen to CASA and sensible aviation. The spin he has been putting out each month is aggravating and nauseating. Thank all mythical omnipotent beings that he is finally going away.
