Aging fleets, rising utilization and regulatory inspection intervals are key drivers. Fuel tanks and pumps, scavenge systems and valves has to face high wear, requiring scheduled overhauls. Airlines preparing for Sustainable Aviation Fuel (SAF) blends are also replacing seals, filters and testing pumps for compatibility. For example, in 2024, Delta began SAF trials at scale, prompting engineering adjustments across subsystems including fuel delivery. As operators adopt SAF at higher blends, maintenance demand for compatible parts will increase. Additionally, OEM partnerships, such as Eaton’s authorized service agreements with Air Support in Europe, shows the drive to localize repair, improving turnaround and lowering downtime. These developments demonstrate how fuel-system MRO is both safety-critical and strategically aligned with sustainability initiatives.

MARKET RESTRAINTS

Certification and Supply Chain Hurdles is a Major Restraint

Despite the rapid growth, various significant restraints challenges the aftermarket. Certification hurdles restricts the use of refurbished components unless backed by OEM documentation and EASA/FAA approvals, limiting cost flexibility. Independent repair shops often face difficulty accessing proprietary manuals or test equipment, which keeps OEMs in a gatekeeper role. Moreover, precision machining and specialty materials for pumps and valves have been vulnerable to supply chain delays since 2021, creating longer lead times. For instance, Lufthansa Technik has warned of longer turnaround times for complex modules, partly due to part shortages. These issues increase costs for airlines, as they may resort to purchasing new OEM spares at premium pricing when refurbished inventory is limited.

MARKET OPPORTUNITIES

Authorized Service Growth & SAF Retrofits Offers Lucrative Opportunity

Beneficial opportunities are arising from expanded authorized repair networks and SAF transition. Eaton in 2024 appointed VSE Aviation in the Americas and Air Support in EMEA as authorized fuel and hydraulics repair providers significantly broadening certified capacity. This allows operators to service components locally rather than shipping units overseas, cutting downtime. Meanwhile, the SAF transition requires ongoing retrofits, as seals, filters and pump components need to be validated for biofuel blends, creating fresh aftermarket opportunities. Airlines piloting SAF flights (United, Delta, KLM) are testing long range durability of fuel systems, driving demand for inspection and modification. Independent MROs that partner with OEMs for authorized capabilities and invest in SAF-compatible test benches are best positioned to capture these contracts.

MARKET CHALLENGES

Skilled Labor & AOG Costs Spikes Deters Aftermarket Expansion

The biggest challenge for the aftermarket lies in skilled labor shortages and the cost of AOG events tied to fuel-system failures. Even with record results, Lufthansa Technik noted pressure to scale workshops and recruit engineers in 2024 as demand surged across components. Fuel-system repairs require highly trained specialists and safety-critical testing, which cannot be easily outsourced. AOG incidents caused by leaking pumps or clogged valves can cost airlines tens of thousands per hour in delays. Additionally, shifting toward SAF and hydrogen adds a layer of training complexity for MRO staff, stretching the limited capacity. These issues emphasize the urgency for both OEMs and independent MROs to invest in workforce development and equipment upgrades to prevent bottlenecks.

COMMERCIAL AIRCRAFT FUEL SYSTEMS AFTERMARKET TRENDS

Hydrogen & Predictive Diagnostics Are Upcoming Technological Trend Reshaping Aftermarket Growth

Emerging technologies are expected to reshape the aftermarket in future. Hydrogen propulsion programs in Europe (HyFIVE consortium, Parker Aerospace involvement) are developing cryogenic fuel pumps, valves and sensors, creating the need for new servicing expertise. For current fleets, predictive diagnostics is becoming more common as onboard sensors and digital twin models feed data into predictive maintenance systems to forecast pump or valve wear before failure. In 2024, several airlines began deploying expanded predictive analytics platforms across A320 and B737 fleets, enabling component swaps before AOG events. MRO shops investing in specialized test rigs, digital calibration and data integration will capture early mover advantage as both hydrogen and digital maintenance ecosystems mature.
