Take a look at the PNG Rules created around the year 2000 and subsequently up to the present time, and compare them against the NZCAA Rules. I think that you will find a striking similarity, and likewise for the common Rules adopted by the countries who have previously signed up to PASO
There is nothing sinister about this Big E; a number of countries adopted the NZ rules (a great pity Australia has not done the same), all done above board.
Likewise it is not the
rules themselves that are a problem; it is the application of the rules, and more particularly the
lack of effective oversight that results in problems. This is reflected in the USOAP audits. This is not a failure of the people employed in CASA PNG, but a failure by the PNG government to devote sufficient resources to the cause.
It's a bit like giving up smoking - for any "quit" program to be effective, you have to
want to change.
