Blockchain-Enabled MRO: Enhancing Transparency and Efficiency in Aircraft Maintenance

Blockchain technology is emerging as a transformative solution for addressing challenges in aviation Maintenance, Repair, and Overhaul (MRO), particularly in enhancing transparency, efficiency, and data security. This study explores the integration of blockchain within MRO operations in the Philippine aviation industry, aiming to assess its impact on data management, part authentication, and regulatory compliance. Utilizing a mixed-methods approach, data were collected through surveys, interviews, and document analysis involving MRO professionals, blockchain experts, and industry stakeholders. Findings indicate that blockchain can significantly improve record transparency, reduce counterfeit risks, and streamline verification processes, leading to more efficient maintenance cycles. Blockchain’s decentralized, tamper-proof ledger system was noted to address inefficiencies in data reconciliation and enhance traceability, which are critical for regulatory compliance. However, challenges such as cost, scalability, and integration with legacy systems were identified as barriers to adoption. The study recommends pilotingblockchain in specific MRO functions, integrating it with IoT for predictive maintenance, and collaborating with regulators to develop industry standards. Future research should focus on blockchain’s long-term cost implications, its synergy with artificial intelligence for predictive analytics, and strategies to overcome regional adoption challenges. Thestudy underscores blockchain’s potential to modernize MRO practices and offers insights into its practical application in a developing market.
