    The aircraft structure is continually faced with requirements for openings at webs and panels to provide access or to let other members such as control rods or cables, hydraulic lines, electric wire bundles, etc., pass through. Other cutouts such as windows, doors, service panels, and hatches. Moreover, an aircraft fuselage can be damaged due to numerous ways such as a bird crash, lightning, hail squall, and a baggage car crash. These structural damages have to be repaired by cutout fuselage. The cut-out repairs with a doubler on the aircraft fuselage are investigated in this thesis. Engineers view any cutouts in airframe structures with disfavor because the necessary reinforcement of the cutout increase costs and adds weight to the overall design. In addition, the design and sizing of cutouts is a difficult process and a problem area for both static and fatigue strength and there is insufficient design data. The main goal of the project is to develop a fast & temporary repair design. When an aircraft is damaged out of the Turkish Technic Inc., the damaged aircraft must be returned as soon as possible. Otherwise, the company must send qualified workers and spend a lot of money like passengers and technicians of hotel & other costs. Thus, the repair's cost will be very high. Furthermore, the repair which is done in the out of the company sometimes gives trouble. This study is aimed to use as a general benchmark for future work in Turkish Technic Inc. This thesis is intended to repair airframe structures that must be calculated in terms of static and fatigue. The thesis shows how to obtain the number of fasteners for fast & temporary repair and fatigue life. Step–by–step calculations are explained for repair design. From a structural standpoint, the thesis is intended to be used as a tool to help achieve structural integrity according to international regulations, specifications, criteria, etc., for designing commercial aircraft. It can also be considered as a troubleshooting guide for airline structural maintenance and repair engineers.
