Rather than hate Casa blindly for the misdeeds against an operator it seems most of its defendants don't seem to know , why not research the 30 year history of the "company" and the engineers. As others have stated its all out there if you look. MacArthur job , atsb , aopa , wheelahan investigation , even a book written by a passenger. As for the rampant unchecked power of Casa against the little GA guy , seemed ok when the boot was on the other foot of a once FOI.
