Cyber Physical Systems (CPS) receiving more and more industrial reality. In this paper a concept for the application of CPS for Aircraft maintenance repair and overhaul, sketched with airline partners, will be given. Based on industrial needs and requirements as well as the current state of the art the concept is describing a direct assignment of MRO-tasks to mechanic, tools and spare parts in order improve aircraft availability. The planning will be supported through simulation based generation of contextual MRO-tasks.
