It still makes no sense. You have to believe that AH executive have the best interests of their business at the forefront of any thinking - so to suggest there is no safety issue would be utter madness without any intelligent reason/rational. Otherwise EC225 crashes elsewhere in world in same circumstance as Norway and they are toast if that reason is a design flaw.
Likewise you have to believe that their engineering boffins are noble and stand up people so suggesting anything otherwise doesn't fit.
So if you believe all of that (and perhaps some don't) then not giving the back story to their findings is just dumb - in fact even more dumb is the inability for the other players in this not to be able to have eyes opened by any private conversations. Beyond which if it's so obvious that a multi billion dollar entity is prepared to bet the lot on a cause then why no news from "official" channels?
