To date 1 x ATR42 already lies in a creek off the end of AYMD R25. Time will tell if the ATR is "Robust" enough for PNG.
And a Dash ended up busted some 10 miles short of AYMD whilst a Fokker over ran the opposite runway, AYMD 07 and ended up as a boat in the harbour.
IMHO, don't think the amount of "robustness" has anything to do with it...skill, airmanship, temperament, knowledge.... and perhaps some luck, but robust...nah.
