The objective in this thread is to discuss the implications of the design reviews and specially the “timing consequences”.
After 2012 considered the safest year on record, aviation industry faces redesign of newer and very important two products.
FAA ordered a review of 787 design and
EADS Airbus activates “Plan B” for the A350 XWB (battery option). The trigger for the 787 grounding and A350 design change were uncertainties presented the high performance Lithium batteries.
The promising technology is under review and delays are expected on it´s broader use in airliners. Currently it has limited use e.g. for emergency lighting in A380. Boeing 787 was the first airliner using it as the only option as MAIN and APU battery. 787 FAA design review covers critical systems, including the design, manufacture and assembly.
