Don, what "unsafe practises" do you speak of? The Archerfield operation is no tin pot hobby farm 1 flight a week school from west of the range! It is a commercial operation and provides many in the industry a start. It would have t be the biggest RAAus school in the country, by far. I'm sure that they've done very well indeed keeping the failure rate down to just that with thousands more hours/sectors flown in jabiru's than anybody else in recent history??
Have you got any proof/evidence of your claim, or is your ego writing cheques your body can't cash!....
