The concept of the Digital Twin (DT) is highly relevant in numerous domains from many perspectives. The possibility to solve descriptive, diagnostic, predictive and prescriptive tasks by using real-time data and diverse models offers the potential to improve processes sustainably. This also applies to the field of aircraft maintenance, where updated digital representations of an aircraft as well as its components, so called Line Replaceable Units (LRU`s), are highly needed in multiple tasks. Recorded data on the condition of these LRU`s as well as their mutual interaction from flight operation are of utmost value for Maintenance, Repair, Overhaul (MRO) service providers in order to carry out fault diagnosis and maintenance planning tasks more efficiently. A major challenge in this endeavour is the difficulty of accessing the data of a LRU, as this data is collected and stored in a wide variety of formats and data sources. Consequently, the necessary flow of information is hampered and restricted. The Asset Administration Shell (AAS) has proven helpful in a wide variety of Industry 4.0 application scenarios and offers the potential to be a solution concept for realising interoperable DT`s. The following contribution aims to highlight the advantages of using AAS in the maintenance of aircraft components. For this purpose, typical use cases and implementation challenges of interoperable DT`s in the area of MRO are illustrated. Accordingly, the use of the AAS including suitable submodels for the representation of information for the fundamental tasks of diagnosis and maintenance planning is demonstrated.
