CEFOSKEY - there is no run-dry capability and no emergency lube system - where is the plan b when the oil pump fails? That is either supreme arrogance on the part of the designers or incompetence.
You can gloss it over as much as you like but designing a modern helicopter that can be brought down by one simple pump failure is poor engineering design.
The reason you get so many end-user comments is because we are the ones who will find ourselves ditching 100s of mile out to sea because someone didn't think about the consequences of a component failure properly. "Hey I know, shall we give the crew some backup in case the MRGB pump fails - hell no they'll just land if that happens"
