Abstract: A method for repairing the skin of the fuselage of an airplane from the inside to be used when the skin of the fuselage has been damaged between a first stringer and a second stringer adjacent to the first one is provided. The method comprises four steps which are: filling the damage, placing a first doubler over the filling, placing a second doubler over the first doubler and bend this second doubler at least over a flange of one of the stringers, and securing the second doubler. If either one of the stringers or two of them adjacent to the damage are also damaged, the present method can be used. This invention also proposes a smaller width of the foot of the stringer object of the present invention than the width of a same stringer designed considering the methods currently used for repair design principles.

Abstract: A re-usable retainer designed to be used in the curing process of co-bonding uncured stringers. The re-usable retainer is made of metal so it is not necessary to manufacture one retainer for each manufactured stringer. The metallic retainer is placed in direct contact with the uncured resin so the cured stringer has a very good surface quality. The re-usable retainer has a special shape that allows a mild transition of the vacuum bag that avoids vacuum bag breakages. The re-usable retainer is easy to install and to remove.
