Is it to much of simplyfing things to relate the MGB problems that have come up(oil pump failure, oil leaking and more) to the M/R vibrations and the roughness of this four blade rotorhead. Is this rotor not just giving this box real tough time??? More than Sikorsky thought, planned it would.
There has been rumor about a 92 B model with one more blade attach to its head, maybe to solve this problems??
Maybe I’m wrong and this is just then bad individual parts that are failing…
I don’t think anyone flying this thing will accept this ONE in TEN mil flight hours for “remote failure”blablabla
Remember Murphy!
Why don’t they just put in this emergency lube system from the Mil variant even if it costs some payload??
Or is it expense versus life here once again??
But to be fair, does anyone of you here remember how many accidents there have been on large helicopter through the years where there was total MGB failure???
