"Cancel CASA's proposed restrictions on Jabiru aircraft engines"
Fewer than 600 signed to date.
__________________________
I thought I read somewhere CASA asked Jabiru to voluntarily impose restrictions on operations, but of course I can't find reference now.
Initially Jabiru accepted it had much work to do, but now seem to be arguing students should be able to deal with an engine failure.
That is the judgement CASA must make. Good luck, Lee Ungermann!
