Abstract The A321neo ACF (Airbus Cabin Flex configuration) contains newly designed Overwing Doors (OWD) that provide an automatic opening function for the case of evacuation. Due to the significant structural differences between the previous “hatch” design used on A319 and A320 aircraft and the new OWD design it has been decided to test the OWD’s and the surrounding fuselage structure to demonstrate the Fatigue and Damage Tolerance capabilities of the structure. This demonstration should be done by means of a fatigue and damage tolerance test. An appropriate test set-up had to be selected. Two generally different approached were investigated. This selection process led to the decision to follow the curved fuselage panel test method. Curved fuselage panel testing was developed in order to test undisturbed, regular panels. During the last years, this method was improved to allow testing of panels with major non-regularities, for instance door cut outs, floor beams or similar features.
