Picture a man sitting at his home computer, editing Authorised Release Certificates for aircraft engine parts. Not ten certificates. Not a hundred. Over 60,000 parts, worth £6.9 million, shipped to airlines and MROs worldwide with paperwork that looked perfectly legitimate.
That’s the AOG Technics case. The UK’s Serious Fraud Office secured a 4-year 8-month prison sentence after investigators traced how one company director doctored genuine ARCs, fabricated shipping memos, and made it appear that parts were purchased directly from OEMs. Safran caught a single fake certificate and pulled the thread. The FAA, EASA, and UK CAA issued safety alerts. Planes were grounded across multiple continents.
The part that should bother every aircraft manufacturer reading this: the fraud ran from January 2019 to July 2023. Four and a half years. The supply chain’s immune system didn’t catch it. A human at Safran did, by accident.
If your parts provenance still lives in PDFs and paper trails, you’re running the same exposure right now.
Why This Hits Manufacturers Harder Than Anyone Else
Airlines and MROs bear the operational fallout when a suspect part grounds a plane. Manufacturers bear something slower and more corrosive: the erosion of trust in their entire supply chain.
IATA’s guidance on life-limited parts traceability spells out the commercial reality. “Back-to-birth” documentation has moved beyond minimum airworthiness regulations. It’s now a de facto market standard. Without full traceability from the moment a part is manufactured through every hand it passes, that part loses resale value and becomes nearly untradeable in the secondary market.
For OEMs, the incentive is direct. Every component you produce carries your name. If that component enters a documentation gray zone downstream, your brand absorbs the reputational damage when regulators start asking questions. Asset tracking here isn’t about logistics efficiency. It’s provenance insurance.
Boeing discovered this on the manufacturing floor. RFID tags on aircraft components cut their part search times by 70%. GE Aviation saw a 40% reduction in inventory discrepancies after deploying similar systems. Those numbers came from production environments, not airline operations. The efficiency gains start where the part is born.
The “Visibility Shock” Nobody Warns You About
I’ve watched this pattern unfold at nearly every deployment we’ve supported. A manufacturer or MRO turns on a new RFID or RTLS system expecting clean dashboards and immediate gains. What they get is a wall of exceptions.
The system surfaces ghost assets: items recorded in the digital ledger that are physically nowhere to be found. Documentation mismatches that lived comfortably behind manual audit cycles suddenly light up in red. The reported discrepancy rate spikes. Stakeholders panic. Someone suggests turning the system off.
This is the most counterintuitive reality of asset tracking in aviation. It makes your operation look worse before it gets better.
Those ghost assets were always missing. Those documentation gaps always existed. The system didn’t create problems. It revealed the ones you were already carrying. Once visible, they become fixable, on your terms, before a regulator or a fraud investigation forces the conversation.
The manufacturers who understand visibility shock treat tracking as a diagnostic tool first and an efficiency tool second. The ones who don’t kill the project after 90 days because “the data quality was terrible.” The data quality was always terrible. They just couldn’t see it before.
The Financial Case That Actually Moves Boardrooms
Spec sheets don’t unlock procurement budgets. Dollar figures do. So let’s talk dollars.
An Aircraft on Ground event costs between $10,000 and $150,000 per hour depending on aircraft type and route. A single misplaced tool on a runway or in an engine cavity triggers a Foreign Object Debris investigation. The FAA estimates annual global FOD costs at up to $22.7 billion, encompassing engine damage, flight delays, and the cascading inspection cycles that follow.
Now add the GNSS problem. IATA data shows GPS jamming events in 2025 increased 67% compared to 2023. Spoofing incidents rose 193% over the same period. When you’re shipping a $2 million engine across continents, confirming its real location (not a spoofed one) is a safety function, not a supply chain feature.
Delta Air Lines built the clearest ROI narrative in commercial aviation. They started by tracking aircraft wheels. Proved the concept. Expanded to tool tracking and baggage logistics. The result: an 18% reduction in mishandled bags and $12 million in annual savings on compensation payouts alone. That’s one airline. For a manufacturer feeding components into dozens of operators globally, the multiplier is hard to ignore.
The broader market agrees. Aviation is the fastest-growing segment in asset tracking, expanding at 11.78% CAGR while the overall market grows at 10.84%. The gap reflects an industry that learned the cost of blind spots through painful, public failures.
What the Right Tracking Stack Actually Looks Like
No single technology covers every scenario in aircraft manufacturing. The environments are too varied: highly reflective metal surfaces in production hangars, global air cargo routes, and part lifecycles measured in decades.
The architecture that works uses three layers, each solving a different problem.
Permanent part identification starts with passive UHF RFID. These tags have no battery. They draw power from the reader’s electromagnetic signal, which means zero maintenance over the lifetime of the component. SAE AS5678 provides the certification framework for tags permanently affixed to aircraft parts, and IATA requires a minimum 4.5-meter read range on metallic surfaces for components with frequent inspection intervals. This layer is your provenance backbone: identity that travels with the part from birth to retirement.
On-site, real-time visibility requires active systems. UWB (Ultra-Wideband) delivers 10 to 30 centimeter accuracy through time-of-flight measurements between tags and fixed anchors, making it the right choice for precision assembly coordination. BLE covers broader hangar areas at 1 to 5 meter accuracy with lower infrastructure cost. For general ground support equipment and tool checkout, BLE does the job. For robotic assembly cells, UWB is the fit.
In-transit visibility for high-value rotables and engines demands satellite and cellular IoT. This is where the technology has changed most in the past few years. Devices like the Thingfox T2, which carries DO-160 airfreight certification, can ride inside the air cargo chain and report location and condition data across borders. NB-IoT over non-terrestrial networks has made satellite connectivity accessible to low-cost, low-power trackers that would have been unaffordable even five years ago.
These layers don’t compete with each other. Passive RFID handles identity. RTLS handles location on-site. Satellite IoT handles location in transit. A manufacturer that picks only one will always have a blind spot somewhere in the chain.
Three Outcomes Worth Measuring
- Part search time drops 50 to 70%. Boeing proved this at scale with RFID. For a manufacturer running multiple assembly lines, that’s labor hours recovered and production throughput gained. Not theoretical. Measured.
- Inventory discrepancies fall 30 to 40%. GE Aviation’s post-implementation numbers. Fewer discrepancies mean fewer emergency procurement cycles, fewer AOG incidents downstream, and audits that don’t derail your quarter.
- Counterfeit exposure becomes detectable before it becomes criminal. Digitized provenance creates an audit trail that flags documentation gaps in real time. AOG Technics ran four years undetected because paper certificates don’t trigger automated alerts. A digital mismatch does. On day one.
The AOG Technics verdict sent a clear signal: enforcement agencies can now prove fraud when the documentation trail is digitized. That same visibility works in your favor when you’re the manufacturer. Provenance tracking doesn’t just protect your parts. It protects your name.
We design these tracking architectures for aircraft manufacturers and MROs, from part-level RFID through global satellite visibility. If your components go dark after they leave the factory, that’s the gap worth closing. Talk to our team, or take a look at the hardware we deploy.
