When cracks along rivet holes and other highly stressed regions of mostly aged aircrafts are found, usually repairs are being made to arrest these cracks. Patches provide an innovative repair technique, which can enhance the way aircrafts are maintained. Composite patch design along with axiomatic design technique deployment is a possibility. Axiomatic Design (AD) is expressed as a system design methodology that is applicable to creation of a new design, analysis and improvement of an existing design. While, here Patch Design system architecture is expressed as application of principles of axiomatic design on top level requirements with consideration of design parameters and constraints. A new conceptual repair process for damaged structures is being developed with zigzagging between AD domains. The full design matrix of repair process will be formed by decomposition of the Composite Patch Repair and systematic step by step presentation of design process. This involves the selection of adhesive material and its thickness, determination of patch dimensions, selection of patch material, repair instructions and finally stress analysis method. It is anticipated that the suggested repair design process will be a useful tool for engineers involved in aircraft maintenance units
