Abstract The objective of this paper was to create a proof of concept for a blockchain application in aviation world, with an emphasis on improving the aircraft maintenance traceability. It is well known that aviation industry manages incredible complex systems, where failure is not an option. This industry needs blockchain technology not only for safety improvements but also for a new business model where airline companies can deliver more trust and more transparency to their customers. Nowadays, the passengers who are the end customers, cannot evaluate an airline company from the point of view of fleet maintenance. Bad or uncomplete maintenance are premises for an undesired accident. Moreover, aircraft investigators and auditors are experiencing difficulties in understanding how an aircraft was operated. Thinking of forecasting defects, models of predictive maintenance cannot be developed if accurate data are not available. All these can be changed with the implementation of the proposed blockchain application. Beside the theoretical explanations, the scope of this work was also to put in practice the main blockchain features and develop on a small scale, a real decentralized blockchain application using Python programming language. The script was designed to run on a localhost machine and store maintenance records and relevant parameters for the process of tracking an airplane’s lifespan in a chain of interconnected blocks. Therefore, the traditional approach in the data management is no longer an option for the aviation industry.
