Encourage growth is quite legit, one can regulate and support or regulate and destroy.
CASA do the latter. look at Whyalla, absolutely no justification for initial knee jerk CASA action. That is regulation by whim (again). Fine, if they are shonky shut em down, but changing regs for the sake of it, shutting operators down without fair process and making the regs too difficult to comply with is killing Australian aviation.
And saying the FAA got in the sh!t over value jet is more knee jerk pandering to ambulance chasing lawyers and journalists.
