Further detailed inspections will reveal what type of repair is required. This may involve some NDT work (Ultra sound, X-Ray etc) which will require specialist equipment and inspectors.
Assuming that the wing and pylon are similar to other Airbus aircraft (which I'm pretty sure they are) there's no doubt that some NDT inspections would be required, probably Ultrasound and Eddy Current, this is fairly straightforward using nice battery powered portable equipment. Although some of the pylon attachment fittings extend up into the wing so would require tank access, they may get away without defueling the aircraft if there's not too much fuel left in there by transferring everything into the centre tank.
