C-19, the original statement which resulted in my query was:
Including the very recent DHC8 BBQ at Mendi, PX has now lost FIVE (5) hulls in less than a decade - pilot error in them all with the 737 yet to be decided maybe
My bolding.
You obviously know more than I do about Air Niugini, but I can't see how the Mendi hull loss event involved pilot error. Certainly it raises questions about Air Niugini's Security system and why it appears to have failed to meet the requirements of PNG CAR Part 108.53 (a), but to pin the event on the pilot seems a bit far-fetched.
