A quick thread observation would be that the MGB incident has all those who ride in the S-92 spooked and wanting to be confident in it once more before getting back on this horse.
Military aviators would simply put this type of issue on the long list of other things trying to kill them and get on with it but civilian types haven't the luxury of having bullets and rockets lobbed at them to help them forget about a questionable MGB issue. I don't believe the helo will ever be as reliable as that most perfect engineering design, the single ball bearing but you can bet SAC works the hardest to make it that way..IMHE.
