It will be interesting to see what comes out of this. If you consider how much pressure CASA puts on local operators it begs the question what does a foreign operator have to do to get it's AOC revoked or investigated by CASA?
Air Asia have had two very close calls in Australia now they're flying past perfectly acceptable alternates on one engine.
My money is on CASA doing nothing as per usual as they are not interested in upsetting a foreign country, and will just continue hammering the local operators and making what is already an uneven playing field even more uneven.
