Hot 'n' High: Thanks for the Barton Birdwatcher link. I had forgotten that one ..a copy of the Malibu Sala story .But those were amateurs trying to do like professionals. In this case, or the PIA Karachi one, we have professionals flying like amateurs.
Passing a safety audit in some places is just like teenagers preparing for an exam . make sure everything is OK on the day , learn by heart or write down somewhere accessible the answers to pass the test, and when it is done and the auditors.examiners are back home , go back as you were doing before.
I have been in so many places ( for ATC business) and watched and flew on so many of these" flexible " air operations. A good example , a small airline in a small poor Asian mountainous country operates Beech 1900s domestically for years , all VFR. Tourism grew and they bought a few ATRs 42 and 72s . They fly those VFR only , with a portable Garmin 196 screwed on the glare shield, just like the Beech were operated. It works..until now at least.
Similar situations in Africa and Latin america.
The world is much wider than FAA/EASA...
