While the foremost priority in the aerospace industry is installing well-produced, conforming parts, even the highest quality products are worthless without a verifiable record of their manufacturing processes, origin, approval, and any previous installations. Traditionally, a paper trail of FAA 8130-3 forms and Certificates of Conformance (CoC) were the sole methods of proving all of this information, such documents offering reliable information, but failing to meet modern expectations for accessibility. On the other hand, the rise of blockchain aerospace procurement strategies has established an alternative for addressing the need for crucial data, where records are managed and presented in a completely digital format that has safeguards in place to make sure only completely accurate data is provided for a part’s journey. For those who are interested in learning more, read on as we discuss the basics of how blockchain technologies drive traceability and how their application benefits supply chains.
Blockchains are a Distributed Ledger Technology (DLT) used in the aerospace sector to organize and maintain a shared record of every relevant National Stock Number (NSN), batch or lot number, material certification, transaction, or maintenance event that is tied to a specific component. Rather than a proprietary portal or a private corporate server that can be vulnerable to unauthorized alterations, a blockchain is maintained by a peer-to-peer network of stakeholders like Original Equipment Manufacturers (OEMs), distributors, procurement officers, and Maintenance, Repair, and Overhaul (MRO) facilities for upholding the reliability and security of data.
When information is entered by certified personnel, it is grouped into secure blocks, each of which is anchored to a precise block timestamp so they appear in a chronological sequence. However, this data cannot be freely entered and approved by any single participant. Instead, data is automatically cross-referenced by a network of authorized servers owned by the aforementioned stakeholders, ensuring that any addition is only locked into the system once stakeholders or network servers reach a consensus for an entry to be deemed as having met technical standards. From there, the information is locked into the blockchain system and is virtually tamper-proof.
Since a blockchain system provides a log of vital data that is backed up by numerous checks, it can be employed in aviation applications to:
The use of blockchain technologies throughout aerospace procurement settings will likely transition from a competitive advantage to industry standard, as it effectively guarantees that records of authenticity and history for any piece of hardware or equipment are cross-referenced for accuracy and readily accessible at every step.
