A few points;
- does CASA really want control and managing 10,000 pilots and 3,000 planes back ? Control probably yes, management workload probably no.
- if criminal actions against RAAus or its officers are successful then insurance may be void. This is probably not what his girlfriend wants if she brings a civil action against RAAus.
- any civil damage award may be reduced by his partial liability (poor decision making) and his girlfriends partial liability ie being too scared to fly with him and her PPL training meaning she knew or should have known she was required to report him to CASA which did not occur.
So we are left with does the cost of legal action and any damages bankrupt RAAus.
This is the real risk which may take 5 years plus to play out.
