The problem is the system. It is in CASA's interest to buggerise around with the regs as this creates activity. Drafting, redrafting, consultation committees etc etc. Years and Years of activity that needs to be funded and managed.
Those at the top have no interest in a quick fix as it will put their power and funding at risk.
So now they have nearly finished the FAA type rules they move the goal posts to more of a Euro style law and it all starts again.
It's all about creating activity.
