Blockchain-based Aircraft Parts Traceability
Sector: Tertiary sector · Industry: Aviation · Organisation: GE Aviation · Maturity level: Production
GE Aerospace uses blockchain technology to create "back-to-birth" traceability records for aircraft engines and parts within the TRUEngine program. This tamper-proof documentation of the complete lifecycle of aircraft parts solves the problem of authenticity verification and unapproved parts in the aviation industry. Through this technology, up to 50 percent higher residual value for used spare parts is achieved and the resale process is accelerated.

Description
GE Aerospace described its blockchain initiative internally as Ancestry.com for engines: every engine part receives a digital provenance chain that seamlessly maps manufacturing, quality tests, initial installation, modifications, maintenance, and owners. ePlane AI and GE Aerospace published articles about this blockchain application in aviation maintenance.
Aviation parts are subject to extremely strict documentation requirements: every safety-critical part must be able to prove its complete history. The problem: this documentation is paper-based, spread over thousands of pages, and prone to errors and forgeries. GE Aerospace uses blockchain to store this data digitally and immutably: from factory exit, each part receives a unique ID; quality inspections, approval tests, and releases are blockchain-documented; with every installation or removal, owner and installation history are updated. Lufthansa Industry Solutions developed similar blockchain systems for the Lufthansa Group's MRO documentation and published several articles on increased transparency in aviation through blockchain. Regulatory relevance: FAA (USA) and EASA (EU) increasingly accept digital documentation as a substitute for paper-based release documents. ifo Institute (2023): study on blockchain technology in German companies shows aviation as one of the most advanced sectors.
Perspectives
B2B — organisations perspective
Airlines and MRO operators can drastically simplify maintenance documentation with blockchain-based component passports: all part histories immediately accessible, approval processes accelerated, counterfeit parts structurally excluded.
B2C — consumers perspective
Passengers indirectly benefit from increased flight safety through better authenticity verification of used aircraft parts. The technology contributes to the overall improvement of maintenance standards and thus to the safety of air traffic.
Employees perspective
Maintenance technicians and quality inspectors gain access to complete digital histories of aircraft parts, improving their decision-making for repairs and replacements. Automated documentation reduces manual paperwork and increases record accuracy.
Benefits
General
- Up to 50 percent higher residual value for used spare parts through verifiable authenticity and complete documentation.
- Tamper-proof traceability prevents the use of counterfeit or unauthorised parts in critical applications.
- Accelerated resale processes and improved portability of assets between different owners.
B2B — organisations
- Reduced maintenance costs and higher efficiency in the supply chain through improved transparency and trust between partners.
Employees
- Simplified quality inspection and decision-making through access to complete digital part lifecycles.
Challenges
General
- High complexity in integrating with existing legacy systems and coordinating between various supply chain partners.
- Need for industry-wide standards and regulatory recognition for the system's full effectiveness.
B2B — organisations
- Significant investments in technology and training required, as well as coordination with all partners in the supply chain.
Employees
- Training requirements for new digital systems and adaptation of existing workflows to blockchain-based documentation.
Technology foundation
The system is based on the Ethereum blockchain combined with Microsoft frameworks and is supplemented by GE's proprietary parts manuals. This technology is particularly suitable as it creates immutable data records, thus ensuring tamper-proof records over the entire lifecycle of aircraft parts.
Implementation examples
TRUEngine programme at GE Aerospace
GE Aerospace wanted to solve the problem of counterfeit or uncertified parts in the aviation industry while maximising the residual value of used parts. The tamper-proof documentation was intended to build trust between buyers and sellers and improve the efficiency of asset transfers.
GE Aerospace implemented blockchain-based traceability for used and life-limited aircraft parts in the TRUEngine programme.
GE Aerospace uses an Ethereum-based blockchain solution combined with Microsoft frameworks to create tamper-proof "back-to-birth" records for aircraft engines and critical components. The system documents the complete lifecycle of each part from manufacture through all maintenance cycles to resale. The implementation was specifically for the TRUEngine programme, which focuses on used and life-limited parts.
Up to 50 per cent higher residual value for used spare parts, accelerated resale processes and improved asset productivity.
The system addresses safety risks from counterfeit parts and economic losses due to lack of transparency in the secondary market. Additionally, manual documentation processes are replaced by automated, blockchain-based systems.
