30 minute rule again? has that not been beat to death? Do you really want to keep flying with no MGB oil in any helo? At that time are you going to trust that some arbitrary demonstration guarantees your safety for xx minutes?
well actually, yes! if the option is to ditch in horrendous sea conditions then continued flight could well be the preferred option.
Let's not forget that SK implied the S92 had 30-min run dry (even though it didn't explicitly say so) and it wasn't made clear that they slipped past that part of certification by arguing that is was an extremely remote failure.
That would have been fine but the oil filter housing was poorly designed with a poor choice of number and quality of fixings - it became a 'not extremely remote' failure.
The poor suckers in the cockpit lined up the final hole in the Swiss cheese by not following the RFM exactly but they shouldn't have been left in that position by poor design and dodgy certification.
The 225 certainly appears to have a design flaw in its epicyclic gearbox but don't hold the S 92 up as a paragon of virtue.
