Airbus procedure in SRM when the depth of corrosion exceed 0.25 mm the removal of the fasteners mandatory to rework corrosion , but it s very difficult to remove fasteners adjacent to corroded area on the gear rib wing top skin .  

RE: A321-200 Wing top skin corrosion .

Wing corrosion is a chronic problem in A320FAM. Airbus SB 57-1154 and 1155 are related with this corrosion. You have to perform one of these SB to eliminate corrosion. Btw, it takes too much time and M/H.
