The VIRTUA Project: A landmark initiative in aviation safety
The VIRTUA project, initiated by the European Union Aviation Safety Agency (EASA), marked a significant step forward in leveraging blockchain technology to enhance aviation safety management. Concluded in September 2024, the initiative was a collaboration between industry leaders such as FPT Software Europe, the International Air Transport Association (IATA), SkyThread, and PwC France. The project’s primary objective was to assess the feasibility and advantages of using blockchain to manage approved aircraft parts and components.
VIRTUA focused on evaluating how blockchain could improve safety management processes for aviation authorities, operators and stakeholders. It explored various blockchain types and their potential applications throughout the lifecycle of aircraft parts, while also considering the impact on regulatory frameworks and industry standards. One of the key findings was the potential for enhanced traceability through ‘back-to-birth’ tracking of aircraft parts. This capability allows for precise tracking of each component from manufacture to retirement, significantly reducing the risk of counterfeit or unapproved parts entering the supply chain, which is a critical safety issue.
Additionally, VIRTUA highlighted blockchain’s ability to improve data integrity via the secure storage of maintenance records and compliance documentation on an immutable ledger. This ensures the accuracy and transparency of safety-critical data throughout an aircraft’s lifecycle. The project also suggested that blockchain could streamline regulatory processes by facilitating more efficient interactions between airlines and regulatory bodies. Transparent records of part histories and maintenance activities could simplify compliance verification, reducing administrative burdens while also enhancing safety oversight.
Furthermore, VIRTUA explored how blockchain could enhance lifecycle management of certificates issued by production organizations and modified by design or maintenance entities. This comprehensive approach promises to improve management and verification processes for aircraft component certifications. Emphasizing collaboration among stakeholders, VIRTUA demonstrated how blockchain could create a shared platform for information exchange between manufacturers, airlines, maintenance organizations and regulators.
The successful conclusion of the VIRTUA project set a precedent for further exploration and implementation of blockchain technology in aviation safety management, across Europe and indeed beyond. Its findings are expected to inform future regulatory frameworks and guidelines for blockchain solutions in aviation safety management. As Nick Careen from IATA noted, “We believe that this project will provide a comprehensive vision on how blockchain solutions could contribute to addressing the issue”. Ultimately, VIRTUA represents not just a technological exploration, but also a potential paradigm shift in how the aviation industry could approach safety management and regulatory compliance.
Beyond VIRTUA: GE Aviation’s innovative approach
While EASA’s VIRTUA project explored blockchain’s potential in aviation safety, GE Aviation has implemented a groundbreaking blockchain solution, transforming operational efficiency and transparency within the sector.
GE Aviation’s sophisticated blockchain implementation creates a ‘back-to-birth’ record for engine components, establishing a digital history for each aircraft part. This system, likened to “Ancestry.com for Jet Engines,” provides a secure, digitized paper trail for used and Life Limited Parts (LLP) in their TRUEngine programs, spanning the entire lifecycle of aircraft parts.
David Havera, GE Aviation’s blockchain expert, highlights that this technology drives residual value for used spare materials up to 50% higher, facilitates faster resale processes, and improves asset transfer productivity. These benefits are crucial in an industry where 45% of commercial aircraft are owned by lessors, with 60% change ownership every five years.
The implementation has yielded substantial benefits, including enhanced real-time parts tracking, improved operational efficiency and the release of millions in unsettled cash. MTU Maintenance, a partner in this initiative, reported the release of over $10 million in unsettled cash from revenue sharing reconciliation.
Industry estimates suggest GE’s blockchain solution could potentially reduce maintenance costs across the sector by billions annually. It ensures that only certified parts are used, minimizing costly failures and streamlining maintenance processes.
GE Aviation has now expanded its blockchain efforts beyond parts tracking, partnering with TE-FOOD to address broader supply chain challenges. They also launched a blockchain-based solution for health screening and aircraft cleaning in response to the COVID-19 pandemic.
This successful implementation serves as a compelling case study, demonstrating blockchain’s potential to address long-standing challenges in aviation operations, ultimately enhancing safety, efficiency and cost-effectiveness.
