This study aims to enhance the traceability, data integrity, and transparency of an aircraft's maintenance records while ensuring the records' privacy using blockchain technologies. In this study, a blockchain-based and decentralized model has been developed that enables the digital distribution of maintenance record reports for air platforms, which can be shared peer-to-peer while ensuring report integrity and content confidentiality upon request. An Ethereum blockchain network with a PoS consensus algorithm is preferred for the application of this study. The proposed secure maintenance record storage system for creating a blockchain network is implemented using Ganache and Truffle. This decentralized model provides a reliable file-sharing process that enhances information visibility and reliability among maintenance, repair, and overhaul (MRO) service providers and other stakeholders.
