Zusammenfassung:
The application of composites introduced a significant change in the structural design for aeronautical engineering. Weight savings, performance increase and reduction in life cycle costs are the achievements for both, operator and manufacturer. Now, airframes are manufactured utilizing nearly 100% of composites as the structural material. Differential construction was replaced by large, highly integrated FRP - components. In case of any damage, large and very expensive parts will be involved. Replacement of the damaged pieces, as it used to be the repair method for conventional constructions, has become fairly difficult and very costly too. The way how to deal with new materials and technologies made aircraft users and services hesitating. Development of repair procedures as well as their approval was essential. The aim of this paper is to discuss standard repair procedures and the various solutions, which have been determined for structural repairs. Repairs on load introduction areas and extensive damages have been rated to require specific repairs and therefore assistance of stress design. Specific repairs will not be discussed hereinafter. This presentation will refer to standard repairs applicable for primary and secondary structures. It will distinguish between "In House Repairs", "Depot and On Aircraft Repairs" and "Field Repairs". It will also refer to suitable NOT - techniques for non-stationary inspection and will discuss aspects to transfer the required standard repair procedures to maintenance personnel.
