I am not saying that somebody should act against procedures. I am just saying that Airbus chose that principle and it's not neccessary the best one. If somebody has a team of people doing procedures based on some other philosophy, I cannot see why not.
what is the qualification of those people that is lacking in the manufacturer? Procedures are based on design philosophy of the aircraft.Nobody has access to that without consultation with the manufacturer.The incident of JetStar had it been an accident relatives of passengers would be justified in dragging the airline to a court of law.
