CASA were really on the proverbial 'hiding-to-nothing' once they'd run their expensive series of explanation/training meetings.
In the face of all their demonstrated inability to answer many quite important questions - they could hardly have persisted and implemented Part 61. There would have been a well defined paper trail right back to the top of CASA - and with a Ministerial Review coming up, they could hardly afford that.
So, the alternative was chosen. Present the delay as being the fault of a dumb industry - and they, CASA, are 'here-to-help'. Then, when the fan has been cleaned - rewrite Part 61 with exactly the same rules included, but couched in ever more legalistic terminology - and viola....we have the final solution!!
happy days,
