The only available cure is to rewrite the Act and then break CASA up into regulator and a separate enforcer.
Folks,
As has been recommended on a number of occasions, and always thwarted by the entrenched bureaucracy.
See right back to the "Lane" reports of the mid-1980s, which coined ( for the first time, to my knowledge) the "mystique of aviation safety" as a mechanism to snow politician and the public with vision of bodies raining from the skies and various other apocalyptic outcomes, if the "air safety expert's" recommendations are deviated from one iota, or their powers over the "privileged" curbed in any way at all.
Indeed, a very senior and influenza CASA "lawyer" (and no,not the good doctor) is on record as saying that neither the Australian aviation community
NOR CASA is sufficiently "mature" for outcome (performance based) regulation and therefor we must have ultra prescriptive regulation to keep the immature committers of aviation and their keepers on the straight and narrow.
You are seeing that policy in action in Part 61/141/142, the whole engineering suite so far, and the rest of the government policy defying regulations about to hit you like the previously mentioned runaway train (or was it a truck).
And the increasingly more obvious result is a shrinking industry and a steadily deterioration record of air safety outcomes.
Tootle pip!!
