OFBSLF, Thanks for the point, but I think that you have missed the point.
What I was inferriong was that the Merlin has found a weakness in a system that all the previous testing was unable to detect. Now that it has occurred, a fix will found.
The S92 has no in srevice time, so I think it is reasonable to expect that there will be some fix required to some critical part at sometime because no matter how much testing is done, something will turn up. Past experience qualifies this assuption.
Using this as a logical base, the US101 must be 'better' than the S92.
To my knowledge there has never been a helicopter built that hasn't had numerous modifications/fixes to solve subsequent problems. Why should the S92 be different?
