Seeems to me that it may well be the same sheet of music when it is accepted by all countries taking part, but different tunes will be played off it. For instance the JAA medical is supposed to be common now bit I recently found that my JAA medical from the UK would still need to be cleared by the local authority in a second European country also issuing JAA medicals to be valid there. So I would still effectivly have to redo the medical. Air Wales found the same with Airworthiness when they brought the Dornier from Iceland. What seems to be happaning is a master Beaurocracy has been wheeled in but the local ones will not give up thier powers either. So there are two layers of red tape and no advantage for the users ( us !). Remember if it was really more efficient that would meen job losses and that will never happan in a CAA !!.
