This led to the grounding of the Caribou - I believe it was a cracked elevator bracket which gave the crew a windscreen of dirt approaching Iron Range. They were so lucky, and the only Caribou flights after that were to storage and museums.
This is incorrect. The broken bracket had more to do with non-RAAF maintenance forgetting to put some bolts in than fatigue. I personally flew several ADF support taks and in PNG following the incident without any concern about airframe fatigue.
