  • Publication number: 20090282664
    Abstract: The invention relates to a method for repairing an aircraft component (10) of fiber reinforced plastic, with the steps of: cutting out a damage site (12) by creating a hole (14), which (i) has a first extent (A1) in a first direction and (ii) has a second extent (A2), which is greater than the first extent (A1), in a second direction, extending transversely in relation to the first direction, and (iii) has a scarfed rim (16), guiding through the hole (14) an inner patch (36), which is formed so as to cover the hole (14) completely from an inner side of the aircraft component (10), closing the hole (14) with a middle patch (26), which has a scarfed rim, the rim of the patch complementing the rim (16) of the hole, and adhesively bonding the patches (26, 36) to the aircraft component (10).
