The antonov 2 is a fun aircraft to own, and yes it requires lots of money to keep it up and running.. Currently CCE is the only an2 airworthy in AUS,, YNT is having issues with the CofA process however i believe its almost completed.
We have based CCE at Lilydale in Victoria for a few months to avoid the QLD storm season, and we will be conducting adventure flights ex yarra valley in it. more info can be found on our website..
