وصله کاری و تعمیرِ روکش های بال و بدنه هواپیما از طریق چسباندن وصله روی بدنه بوسیله مواد دوپی.
A repair made to a fabric-covered aircraft wing in which an entire panel of fabric from the leading edge to the trailing edge, between one or more ribs, is replaced. The new fabric is attached to the old fabric by doping it in place, rather than sewing it in, but it is attached to the structure by rib stitching.
