Agree with some of your comments NCD, these kind of accidents relating to pilots intentionally breaking hard rules aren’t only related to ANG. There are a couple of other recent accidents that have occurred in PNG where the Captains had pushed on and ended up killing themselves and others.
The check and training standards certainly were tough when I was on the Dash with ANG. A failed check actually triggered my departure, which most people would be aware of, however on reflection after the dust had settled I was actually very grateful for the Checkie’s decision on the day to fail me, as it has made me a better pilot with regards to how I interpret and apply standards.
