Thanks a lot XWB!! Did you know why some Tail-Fin are painted before entered S40 (Finnair) and some other (Qatar and Vietnam Airlines) are painted together with the plane?
I think I read somewhere that QR didn't want people to see a painted tail before their first aircraft was painted. As for VN, perhaps they had yet to finalise their new livery by the time their first aircraft entered the FAL. I believe all tails on the Airbus test fleet were painted before the aircraft entered the FAL.
