Regarding Certification to latest FAR/JAR and the implication on safety I have to play Devil's advocat:
The real irony is that besides the S-92 which is certified according to latest FAR/JAR standards and has a serious design flaw with the MGB, the other Helo which fully fulfills the standards (AW139) on paper likes to shed its tail after less then 5 years of service life.
So much for
Fatigue and damage tolerance of structure
Unfortunately the manufacturers fulfilled the new rules maybe by the books but unfortunately not by the spirit of the rules.
Therefore I would not overrate this compliance stuff. It's good design that counts not paperwork....
