I agree HC, It does seem to be happening on a particular airframe every time. (certainly in our company). At least we can rule out the fact that it's a "north sea problem only".
I currently fly the 92, Am I happy about this - no, Am I happy Sikorsky are on top of it all - yes. I also trust our engineers. Interesting how It's been happening recently & not since it's introduction.
Let's hope they can finally sort the problem soon,
