This particular airplane (F-GZCP) was involved in a ground collision incident with another Airbus in 2006, where its wing hit the other Airbus' tail. The wing was repaired. An improper fix would certainly lead to an in-flight breakup after many operating cycles (see Japan Airlines flight 123 - http://en.wikipedia.org/wiki/JAL_123 http://en.wikipedia.org/wiki/JAL_123; China Airlines flight 611 - http://en.wikipedia.org/wiki/China_Airlines_Flight_611 http://en.wikipedia.org/wiki/China_Airlines_Flight_611 for example), especially in conditions of heavy turbulence that this airplane obviously experienced. Either that or a bomb is my educated speculation.
