Tapini maybe ? Caribou crash as a result of hypoxia and misjudged approach I believe, circa early 1970’s.
Coming from Lae via Woitape/Fane would need an S turn to follow the goat track ILS before turning left on finals - it crashed just before the threshold.
also there was another one that landed at Olsobip by mistake - crew decided to take offf without performance charts and did not get airborne, also mid ‘70s I think.
i believe it was choppered out in bits ???
