If I can just go back right to the very beginning of this thread and quote Dick Smith:
"It has been claimed that one of the reasons Rossair has gone into administration is because of the terrible accident they had"
It is my understanding that the reason Rossair were unable to operate under their own AOC was due to CASA flatly refusing to approve any Chief Pilot put forward by them. I can only assume that CASA had identified systemic cultural issues within the company and used their power in this way to ensure Rossair remained grounded.
Perhaps I'm wrong???
