So where's the beef? The video by simpleflying in the linked article has pretty nasty looking pictures. It seems that a number of airlines have seen this problem, and that it can cause the anti-lighting metal mesh to be exposed or even compromised, also exposing the composite structure underneath to the elements. Airbus seems to be saying Quatar have been incorrectly characterizing this as a safety issue. So who's right on technical merits and what are Airbus doing to resolve this?
