Brian - I think the RFM comment of Smell's relates to the 'Land Immediate' when oil pressure is less than 5psi. It seems that is what the CHC crew did and they lived.
Zalt - One does wonder, reading those two e-mails, how urgently the Broome investigation was really taken by CHC, SAC and TSB.
HC - You can't bu flight safety for $10k - but a wonder how much cheaper the subsequent steel bolts actually are! I bet SAC paid more for the fancy titanium ones that caused the oil loss, even before the court settlements.
