Concerns over the safety and the maintenance cost have been raised over the last years in the airline. The important elements in maintenance of aircraft structural parts are the inspection threshold, repair classification, minimization of the structural damage (e.g. floor panel) and economic consideration of repair. The thesis focuses on the testing and analysis: The testing consists of several types of repair and new floor panel configurations. The analysis considers a new aircraft design in view of maintenance and Life Cycle Cost. The repair configurations consist of current riveted repair, bonded-riveted repair and the usage of Glare as a repair material. The application of Glare sheet on fuselage repair is appropriate for damage tolerance of riveted repair. Adhesive as a faying surface in riveted repair improves the fatigue life significantly as well as the static strength. The combination of Glare sheet with bonded-riveted repair results in the highest fatigue life.
