I hardly think CASA is treating CYA unfairly, under the present management regime they have had more accidents and incidents in the past 2 years than CYA has seen in the previous ten years, work that one out.
The recent PA31 and C208 is the tip of the ice berg, I would hate to see the end of CYA, but it's certainly not looking good for them.
Note: the C206 fatality was before the present managements appointment.
On a personal note I studied under their present GM, he is a fool.
Any operator with the 2 year track record of CYA should expect the latex glove treatment.
