Aerospace Inventory Management: $60B Hiding on Your Shelves

Commercial aerospace inventory hit $240 billion in 2024, up from $167 billion less than a decade ago. McKinsey found that 60 to 80% of the parts value sitting on manufacturers’ shelves won’t be needed for the next twelve months. If you’re involved in aerospace inventory management, that’s not a rounding error. That’s a $60 billion distortion hiding in plain sight.

You already feel this if you run parts for an airline, MRO operation, or aerospace supplier. Too much inventory on the books. Not enough of the right parts on the shelf when they’re actually needed. AOG events that drain $150,000 per hour while the required component is theoretically “in stock” somewhere in a system that hasn’t been updated since last Tuesday.

Aerospace inventory management isn’t a storage problem. It’s a visibility problem. Here’s what that looks like today, what the operators getting results are doing differently, and where the technology is actually heading (not the vendor pitch version).

What Aerospace Inventory Management Actually Means

At its core, this is the systematic control of aircraft spare parts, rotable components, consumables, tooling, and materials required for maintenance, repair, and overhaul. Every other industry uses a similar definition. What separates aerospace is the regulatory and safety infrastructure bolted on top of it—a framework of aerospace quality management that permeates every stage of inventory control.

Every part installed on an aircraft must be traceable to a certificate of origin: an FAA Form 8130-3, an EASA Form 1, or equivalent documentation. Its entire chain of custody, from manufacturer to distributor to installer, must be documented and auditable. The AS9120B quality standard, developed by the International Aerospace Quality Group, builds on ISO 9001 and adds distributor-specific requirements: counterfeit-parts prevention, supplier oversight, obsolescence planning. Miss a step and you fail the audit. Fail the audit and you lose your authority to distribute.

Then there’s the demand profile. A 30-year-old airframe still needs OEM-grade spares. The global commercial fleet averages roughly 15 years old, and that number keeps climbing. Older fleets mean more frequent scheduled maintenance, more rotable demand, and more pressure on aftermarket suppliers to stock parts for aircraft programs that original manufacturers have long since deprioritized.

And the cost of failure is immediate. Industry figures put Aircraft on Ground losses between $10,000 and $150,000 per hour, depending on aircraft type and route disruption. A single grounded narrowbody costs an operator millions per day. AOG is the reason aerospace operators carry safety stock that any other industry would consider irrational. The real question is whether they’re carrying the right stock, or just more of everything.

$240 Billion in Stock. Up to $60 Billion at Risk.

The numbers make the case better than any argument.

McKinsey’s analysis documented more than $70 billion of inventory growth in under a decade. Certain manufacturers found 60 to 80% of their on-hand parts value was excess to the next twelve months of production needs. The firm estimates the aerospace and defense industry risks burning through an additional $60 billion in cash if inventory and planning processes aren’t fixed during the current production ramp-up.

Meanwhile, the market for managing all of this keeps expanding:

Air-travel demand is growing 5 to 10% annually, with order books for roughly 15,700 new aircraft waiting for delivery. Demand recovered. Supply hasn’t. And the gap between “parts we hold” and “parts we need right now” keeps widening.

Five Forces Reshaping Aerospace Inventory Right Now

1. Personnel shortages

According to the Roland Berger Aerospace Supply Chain Report 2025, 65% of supply-chain executives cite personnel shortages as their top challenge. This barely improved from the prior year. You can’t digitize your way out of a workforce gap when the people who know which parts go where are retiring faster than replacements can be trained.

2. Counterfeit parts at industrial scale

The FAA estimates roughly 2% of the 26 million parts installed on U.S. aircraft every year are counterfeit. That sounds small until you do the math: over half a million suspect components entering service annually.

The 2023 AOG Technics scandal made this concrete. More than 100 aircraft operated by American, Delta, Southwest, Virgin Australia, Ryanair, and TAP Air Portugal were grounded to remove bogus parts bearing forged documentation. The firm’s director was sentenced to four years and eight months for a $7 million fraud scheme. Meanwhile, EASA’s Suspected Unapproved Parts program has logged 7,997 cases since 2017, including forged EASA Form 1 and FAA Form 8130-3 documents, stolen Airbus A330 identification plates, and uncertified Rolls-Royce engine components.

This isn’t an edge case. It’s a systemic vulnerability that directly shapes how inventory must be sourced, verified, and tracked.

3. Persistent supply-chain disruption

Roland Berger reports 64% of respondents still experiencing disruptions, with 49% citing lack of financial resources (up from 41% the year prior). Lead times for critical components remain stretched, raw materials constrained. The production ramp-up that was supposed to ease pressure has been pushed back repeatedly. Recovery to full production rates may still take through 2026.

4. Aging fleets driving rotable demand

The global commercial fleet averages roughly 15 years old. Older aircraft require more frequent scheduled maintenance, which drives higher demand for rotables and expendables. OEMs that shifted focus to new-generation programs have deprioritized legacy spares. Independent aftermarket providers (AJW Group, FDH Aero, GA Telesis, AAR Corp) are filling that gap, but inventory positioning for long-tail demand requires forecasting that most operators still handle with spreadsheets.

5. Escalating cyberthreats

64% of aerospace executives reported increased cyberattack threats in the 2025 Roland Berger survey. Inventory systems connected to ERP platforms, supplier portals, and logistics networks create a broad attack surface. A ransomware event that locks your MRO system doesn’t just disrupt maintenance scheduling. It blinds you to your entire parts position.

The Technology Stack That Actually Works

Talk to an aerospace inventory manager about technology and you’ll hear about their MRO software. Sometimes their ERP. Occasionally a forecasting tool. But the stack that delivers results has five layers. The one most commonly neglected is the physical one.

Layer 1: MRO and material management software

This is the system of record. Four platforms dominate aviation-specific inventory:

• AMOS (Swiss Aviation Software): cloud or on-premise, built by airlines for airlines. Deep engineering configuration and maintenance forecasting. Deployed at Lufthansa Technik, Air France, ANA, Korean Air.
• Ramco Aviation MRO: cloud-native, end-to-end coverage across line, component, engine, and hangar maintenance. Launched Aviation Software 6.0 in early 2025 with agentic-AI workflows and drone/eVTOL applicability.
• TRAX eMRO: cloud-based, strongest in compliance tracking and technical records.
• Quantum Control: aviation-specific ERP for part distributors and MROs, with accounting modules built for the broker model.

OASES Aviation Materials Management serves the mid-market with procurement automation for smaller airlines and MROs.

Layer 2: Enterprise ERP

For OEMs and Tier-1 suppliers, the MRO suite sits inside SAP S/4HANA, Oracle SCM Cloud, or IBM’s Maximo Application Suite (which combines AI-driven inventory optimization with predictive maintenance scheduling). These platforms handle accounting, procurement, and cross-functional integration that dedicated MRO suites don’t.

Layer 3: IoT, RFID, and physical-layer tracking

This is where most aerospace inventory programs have a blind spot.

MRO software and ERPs are systems of record. They log what should be true based on the last manual scan, warehouse receipt, or transfer form. But between those checkpoints, parts move. They get pulled for a job and returned to the wrong bin. They ship to a customer site and sit in quarantine for weeks without a status update. They circulate through repair loops spanning multiple facilities and months of elapsed time.

IoT-based asset tracking closes that gap. RFID tagging at the bench level enables real-time location, condition monitoring, and forward linkage to a digital twin of the part. Cellular and GNSS trackers extend visibility beyond the warehouse: transit lanes, customer facilities, MRO loops, bonded storage. For airfreight, DO-160 certified tracking hardware matters because devices that aren’t approved for the aviation environment can’t legally ride with cargo in many jurisdictions. That same continuous visibility is central to air cargo risk management, where parts in transit are most exposed to loss, damage, and delay.

The pattern I see repeatedly in the field: operators invest in six-figure MRO software but feed it with manual scan data that’s hours or days stale. The system dashboard looks clean. The shelves tell a different story. If your physical tracking layer doesn’t provide continuous, automated position and condition data for high-value rotables and tooling, your MRO system is displaying a best guess. Not ground truth.

Layer 4: Blockchain for chain-of-custody verification

The counterfeit problem has made provenance verification a priority. GA Telesis published a framework recommending permissioned enterprise blockchains (Hyperledger Fabric is the most commonly cited) to anchor parts-provenance records so they can’t be modified after the fact. The vision: every ownership transfer, maintenance event, and certification document on an immutable ledger.

Most operators aren’t there yet. But the regulatory trajectory is clear. EASA and the FAA are expected to mandate digital maintenance records within the next two to three years. Operators who build traceability infrastructure now avoid scrambling later.

Layer 5: AI and agentic decision-making

AI is applied to demand forecasting (especially for rotables with lumpy, hard-to-predict demand patterns), safety stock optimization, automated warehouse picking with computer vision, and increasingly “agentic” decisions: should this part be bought, repaired, exchanged, scrapped, sold, or repositioned?

McKinsey estimates AI-driven early-warning systems can reduce component shortages by roughly 25%, and root-cause analysis can cut shortages by around 30%. The AI-in-inventory market is compounding at 29.6% CAGR.

But buying AI and using it are different problems. More on that in a moment.

Three Operators Who Changed Course

Spirit AeroSystems: 16% inventory cut, $60M freed

Spirit AeroSystems reduced manufacturing inventory by 16%, freeing approximately $60 million in working capital. The approach wasn’t exotic: AI-assisted procurement prioritization, supplier-risk scoring, and shop-floor execution data fed into a central decision layer. The lesson, and it keeps repeating across the industry: the tools exist. Data quality and floor-level discipline determine whether they produce results or dashboards.

Lufthansa Technik: the digital warehouse

Lufthansa Technik runs one of the largest independent MRO parts-logistics operations in the world, anchored in Hamburg. Its Digital Warehouse program uses autonomous storage, automated retrieval, RFID-based asset tagging, and AI-driven picking across a spare-parts operation that serves hundreds of airline customers for AOG support. Their stated goal: “to become the innovation leader of spare parts logistics for aircraft.” It’s the most visible aerospace inventory transformation underway in Europe, and it demonstrates what happens when an operator treats physical-layer tracking as infrastructure, not an afterthought.

DLA Aviation: modernizing the world’s largest military stockpile

In August 2024, the U.S. Defense Logistics Agency Aviation rolled out a modern Warehouse Management System targeting improved operational efficiency and warfighter support. Prior DoD Inspector General audits had flagged chronic over- and under-stocking of C-130 spares for years. The Air Force’s Integrated Logistics System (ILS-S) tracks every item in its inventory, but tracking and optimizing are different verbs. DLA’s deployment is now the benchmark for government-side aerospace inventory modernization.

Where Aerospace Inventory Management Is Heading

Before looking forward, a reality check on today.

The Roland Berger data tells a contradictory story: 65% of aerospace supply-chain executives are using or planning to use AI. Simultaneously, 61% lack in-house AI experience, and 53% report integration problems with their existing systems. The industry is buying the technology faster than it can operationalize it.

The operators who’ve moved past this paradox share three traits. They fixed data quality before deploying AI (clean master data, reconciled physical counts against system records). They integrated AI with existing MRO platforms rather than replacing them. And they invested in physical-layer tracking to feed AI with real-time data, not stale scan records. Without that foundation, AI becomes an expensive forecasting tool layered on dirty data. It generates recommendations. They just don’t match what’s actually on the shelf.

With that context, here’s what’s coming.

Digital passports will become mandatory

The convergence of IoT data, digital twins, and blockchain is producing what the industry calls a “digital passport” for parts: a unified, auditable, on-ledger record of every component from OEM to installation. GA Telesis’s WILBUR platform, Airbus Skywise, and Honeywell GoDirect all point at the same destination. By 2027 or 2028, EASA and the FAA are expected to formally mandate digital maintenance records. This will force inventory systems to expose cryptographically verifiable provenance, and it will reward operators who built their traceability infrastructure early.

Used Serviceable Material (USM) will reshape the aftermarket

KPMG’s Aviation 2030 study estimates that certified USM parts are typically 20 to 40% cheaper than new parts, with engines being the most disassembly-friendly category. ICAO’s 2025 Environment Report affirms that MRO providers extend component lifecycles and reduce demand for new materials through refurbishment programs. New models like Spare Parts as a Service decouple part “ownership” from “availability.” The value proposition shifts from holding stock to guaranteeing uptime.

Agentic AI will make autonomous inventory decisions

The evolution beyond forecasting is autonomous action. AJW Group’s “Chia” platform is an early example: an agentic AI layer that doesn’t just recommend buy-repair-scrap decisions but executes them within defined parameters. As the technology matures and trust develops, expect the human role to shift from “approve every transaction” to “set parameters and handle exceptions.” Operators who resist this shift will find their inventory carrying costs increasingly uncompetitive.

Subscription models will commoditize rotable pools

Rolls-Royce Total Care, Lufthansa Technik Total Component Support, and AJW Aviation Pathways already bundle inventory risk into subscription contracts. Airlines pay for uptime, not for shelves of parts. This model will expand, and it will redefine what “inventory management” means operationally: instead of managing 50,000 SKUs internally, operators will manage a handful of pooling contracts and the tracking infrastructure that proves their contractor is hitting SLAs.

Across all of these shifts, one thread is constant: the operators with the best physical-layer visibility (knowing where parts are, what condition they’re in, who moved them last) will absorb change faster than those still relying on periodic manual counts and stale system data. Software handles the system of record. Regulation handles compliance. But the IoT-level tracking that connects shelf reality to every other layer of the stack is still the weakest link for most aerospace operations.

That’s the gap we work on at Datanet IoT Solutions. If your rotable pool, tooling inventory, or high-value components go dark between scan points, reach out. It’s a solvable problem.

Frequently Asked Questions

What is aerospace inventory management?

The systematic control of aircraft spare parts, rotable components, consumables, tooling, and materials required for MRO operations. Unlike generic warehouse management, it requires full traceability to certificates of origin (FAA Form 8130-3, EASA Form 1), compliance with AS9120B quality standards, and documented chain-of-custody records for every transfer from manufacturer through installer.

How much does Aircraft on Ground (AOG) cost?

Industry references put AOG losses between $10,000 and $150,000 per hour for a narrowbody, depending on the route and operational disruption. A single grounding event can cost an operator millions per day in lost revenue, crew rescheduling, and passenger compensation. AOG economics are the primary reason aerospace operators carry safety stock at levels that would be irrational in other industries.

What software platforms lead in aviation inventory management?

The top dedicated MRO and inventory platforms are AMOS (Swiss Aviation Software), Ramco Aviation MRO, TRAX eMRO, and Quantum Control. Enterprise ERPs with aerospace depth include SAP S/4HANA, Oracle SCM Cloud, and IBM Maximo. OEM-controlled platforms like Airbus Skywise, Boeing Distribution, and Honeywell GoDirect add analytics-as-a-service layers for fleet operators.

How big is the aerospace inventory management market?

The aircraft part inventory management segment is estimated at $4.6 billion in 2026, projected to reach $8.1 billion by 2035 at a 6.5% CAGR. The broader MRO market stands around $89 billion, heading toward $145 billion by 2035. The AI-in-inventory-management category is growing fastest at 29.6% CAGR, reaching a projected $30 billion by 2035.

How do I reduce counterfeit-part risk in my supply chain?

Four pillars: require FAA Form 8130-3 or EASA Form 1 documentation for every part; source exclusively from ASA-100 or AS9120B accredited distributors; perform physical inspection of packaging, serial numbers, and dimensional tolerances; and participate in FAA and EASA Suspected Unapproved Parts reporting programs. The AOG Technics case demonstrated that documentation alone fails when the documents themselves are forged, which is why physical-layer traceability and blockchain-anchored provenance are gaining traction.

How is AI changing aerospace inventory management?

AI is applied to demand forecasting for lumpy rotable requirements, safety stock optimization, predictive maintenance scheduling, and “agentic” decisions (buy, repair, scrap, or reposition). McKinsey estimates AI-driven approaches reduce component shortages by 25 to 30%. The adoption gap remains significant: 65% of executives plan to use AI, but 61% lack the in-house experience to integrate it into existing MRO workflows effectively.
