That's why, Daniel...Boeing does it better, safer and stronger--they recognize the FAA/JAA certification "standards" to be the "sub-standards" they really are.
Following the AA crash, AW&ST asked Boeing and Airbus about their respective approaches to the FAA's minimum design criteria for transport vertical stabs. This criteria basically says it's OK if the rudder and/or vertical stab fall of after being cycled full-scale more than once.

Boeing stated that the FAA design spec was ludicrous, and that boeing over-engineered the vertical stuff by a massive factor.

Airbus, when asked the same question..."No Comment"
