VL - drills for low MGB oil pressure where there is either a run-dry capability (however limited) or an emergency lube system where the manufacturers have recognised all the possible failure modes is fine and to be expected on all helicopters.

Drills for low oil pressure on an aircraft that has neither run dry nor ELS seem to fly in the face of 'extremely remote failure' and move more towards 'sh8t can happen, you're on your own but we've put a drill in the RFM so it's not our fault'.

Unfortunately it would appear that Sikorsky have vastly underestimated their clever design and managed, somehow, to get certification of a modern helicopter that has a glaring achilles heel. SK and NL made a huge deal when marketing the S92 of how the new certification made for a super-safe helicopter, especially when compared to older rivals. Are there any other holes in this process waiting to catch people out?

Horror Box - good post, hope someone is listening!
