Frank,
I'm not an making excuses for CASA, but your statement that CASA:
Does not appear to have a mission statement...
is incorrect.
CASA's mission statement is at
Civil Aviation Safety Authority - About CASA as follows:
To enhance and promote aviation safety through effective safety regulation and by encouraging industry to deliver high standards of safety
Whether CASA's achieving (or is in fact actually capable of achieving) that mission seems to be the main issue here I think.
