Ensuring Zero-Failure in Aerospace Component Manufacturing
Industry: Aerospace & Defense
Client Overview: A Tier-1 supplier of critical turbine blades for commercial aircraft engines. The client faced immense pressure to provide 100% verifiable quality assurance for every single part, as even microscopic defects could lead to catastrophic failures. Their existing paper-based and siloed digital systems were slow, prone to error, and made multi-party audits incredibly cumbersome.
"Errna didn't just sell us a technology; they engineered a new level of trust into our production line. The ability to instantly pull up the complete, immutable history of any component has transformed our relationship with both regulators and clients."
- Michael Harper, Director of Quality Assurance, Aerospace Innovations Inc.The Problem
The client needed to create an unchallengeable "birth-to-flight" record for each turbine blade, tracking everything from the specific batch of raw alloy to the final non-destructive testing (NDT) results. This data was fragmented across their own systems, supplier records, and third-party testing labs, making comprehensive quality verification a month-long process.
Key Challenges
- Inability to rapidly prove provenance and quality during audits.
- Risk of counterfeit materials entering the supply chain.
- High administrative overhead for compiling compliance documentation.
- Lack of real-time visibility into quality deviations during multi-stage production.
Our Solution
We implemented a private Hyperledger Fabric blockchain to serve as a single source of truth. A unique digital identity was created for each turbine blade at the point of forging. IoT sensors on CNC machines and testing equipment automatically recorded critical manufacturing parameters and inspection results directly to the blade's digital passport. A permissioned portal allowed suppliers and certified testing labs to add their data, creating a complete, time-stamped, and immutable lifecycle record.

Any temperature deviation could render a multi-million dollar batch of medicine useless and posed a significant risk to patient safety.
"The cold chain was our biggest vulnerability. With Errna's blockchain solution, we now have a tamper-proof record of every batch's journey. This has not only satisfied regulators but has given our distributors and healthcare providers a new level of confidence in our products."
- Dr. Elena Ford, Head of Operations, BioPharma SecureThe Problem
The client needed an unbreakable system to track each drug batch from manufacturing to the pharmacy, with a special focus on monitoring and verifying temperature conditions throughout transit. Their existing data loggers were isolated, and the data could be easily manipulated or lost, creating significant compliance and safety risks.
Key Challenges
- Difficulty proving an uninterrupted cold chain to regulators.
- High risk of product spoilage due to temperature excursions.
- Vulnerability to counterfeit drugs entering the supply chain.
- Inefficient, manual processes for handling batch recalls.
Our Solution
We deployed a consortium blockchain where the manufacturer, logistics partners, and distributors could participate. We integrated IoT temperature sensors into the shipping containers, which streamed data directly to smart contracts on the blockchain every 15 minutes. The smart contracts were programmed with the drug's specific temperature stability profile. If a deviation occurred, an alert was automatically triggered to all stakeholders, and the status of the batch was flagged on the ledger, preventing it from moving further down the supply chain.

- Ava Lyons, CEO, PowerCell TechnologiesThe Problem
The client needed to track and verify thousands of individual cells that make up a single EV battery pack. This included proving the ethical sourcing of raw materials, recording the results of every charge/discharge cycle during testing, and creating a reliable history for future warranty claims, servicing, and end-of-life recycling.
Key Challenges
- Proving ethical and sustainable sourcing of conflict minerals.
- Managing complex warranty claims without a reliable performance history.
- Lack of a trusted data set for second-life battery applications (e.g., energy storage).
- Differentiating their product based on quality and transparency in a competitive market.
Our Solution
We developed a "battery passport" solution on a public, permissioned blockchain. Each battery pack was given a unique digital identity linked to its physical serial number. We worked with their suppliers to record the provenance of raw materials on the chain. During manufacturing, every key metric from cell formation to final pack assembly and testing was appended to the passport. Automakers could then be given secure access to view the complete, immutable history of each battery pack they purchased, creating an unprecedented level of trust and simplifying future servicing.

Frequently Asked Questions
Traditional databases are centralized and controlled by a single entity, meaning data can be altered, deleted, or become a single point of failure. Blockchain is a decentralized, distributed ledger where data is immutable—once recorded, it cannot be changed. This creates a single, shared source of truth that all parties (suppliers, manufacturers, regulators) can trust without needing to trust each other, eliminating disputes and fraud.
Absolutely. Our core competency includes seamless system integration. We design our blockchain solutions with APIs to connect with your existing enterprise systems like ERP, MES, and SCM. The goal is to enhance your current infrastructure by providing a trusted data layer, not to rip and replace what already works.
The cost varies significantly based on the complexity of your manufacturing process, the number of integration points, and the chosen blockchain platform. We typically start with a paid discovery phase or a Proof of Concept (PoC) to define the scope and provide a detailed ROI analysis and budget. This approach ensures you understand the value and costs before committing to a full-scale implementation. Our goal is to ensure the solution pays for itself through reduced defects, lower recall costs, and improved efficiency.
We prioritize user experience. For your suppliers, we design simple, intuitive web portals or mobile apps. The complexity of the blockchain is hidden behind a user-friendly interface. They might be interacting with a simple form to upload a Certificate of Analysis or scan a QR code, while our system handles the complex task of writing that data securely to the blockchain. We also provide comprehensive training and support to ensure smooth onboarding for all partners.
We work with you to determine what data provides the most value for QC. This often includes supplier information, raw material batch numbers, timestamps, machine parameters, inspection results, and shipping details. For security and performance, we often use a hybrid approach: the verifiable proof and key data points are stored on-chain, while larger files (like detailed CAD drawings or high-res images) can be stored off-chain with a cryptographic hash on the blockchain to ensure their integrity. We use enterprise-grade encryption and permissioned access so only authorized parties can view specific data.
A typical timeline starts with a 4-6 week Proof of Concept (PoC) to validate the core functionality for a specific use case. A full production-level implementation can range from 4 to 9 months, depending on the scale and complexity. We follow an agile methodology, delivering value in iterative sprints, so you can start seeing benefits long before the final project is complete.
