I would bet folding money if the UK CAA, US FAA, NZ CAA or CASA got involved with 'regulating' PNG aviation matters the place would grind to a halt in a week.
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 seems to be little or no evidence of grinding to a halt in PNG?
