Well spelled out? Really?
Of the two CHC documents:
1) Is an occurrence report that covers events up to landing
2) Is an email that mainly focuses on the poor service history of the S-92 gearbox
The other documents (and yopur second link) mostly relate to the lab testing. I was well aware of those investigative documents.
However there are no comments on any of the possible safety actions I would have expected would have been considered:
Safety alert on repair authorisation?
Tighter maintenance control at Broome?
Change in maintenance programme?
A notice to crew about oil loss and what 'Land Immediately' means?
revised training?
