I fully agree with your last paregraph. Changes to Airbus SOP done by Chief pilot etc are based on their own interpretation of some earlier incidents. What is forgotten is that Airbus is in touch with all Airbus operators and they collect information about all such incidents that occurr around the globe. Then they develop procedures using all the software, hardware, engineering information available to them which is not available to individual airline. If some perticular difficulty is experienced in day to day operation it should be referred to the manufacturer first before changing any procedures especially in FBW a/c. Offcourse even manufacturers are not immune from making mistakes but it is better to take them in confidence than do a knee jerk change.
