This is either a complete coincidence or just another picture of the last airbus aircraft that have been lost at this kind of altitude. Any rear pressure bulkhead repairs that may have been carried out in the past (assuming previous posts are correct) would have been carried out in accordance with airbus and approved. Any damage outside of the structural repair manual is routed through airbus for an approved repair with approved inspection intervals. It is about time all these sofa based people with an Un educated opinion got a grip.
