Aviation Sector Adopts MRO Lite Amid Delivery Delays and Rising Costs
Airlines adopt MRO Lite strategies using quick-turn maintenance and green-time modules to manage aging fleets amid OEM delivery delays and rising costs.

The global aviation sector is currently navigating a severe squeeze between surging passenger demand and chronic supply chain constraints. With Original Equipment Manufacturers (OEMs) like Boeing and Airbus facing persistent delays in delivering new-generation aircraft and engines, airlines are being forced to operate aging fleets far longer than originally anticipated. This dynamic has created a significant bottleneck in maintenance facilities and is driving up operational costs across the industry.
To mitigate the financial strain of maintaining older aircraft, operators are increasingly pivoting away from traditional, heavy engine overhauls. According to a recent industry outlook authored by Asim Chalise, VP of MRO Sales at AerFin, airlines are adopting “MRO Lite” strategies. This approach focuses on quick-turn, targeted maintenance and module swaps to keep planes flying safely while minimizing capital expenditure.
By utilizing “green-time” components, partially used but highly serviceable parts, airlines are finding a vital bridge to sustain operations until OEM delivery schedules stabilize. However, as the industry leans heavily into this secondary market, questions are emerging about the long-term sustainability of the green-time supply chain.
The Economic Squeeze and the Shift to MRO Lite
The Exorbitant Cost of Aging Fleets
Passenger traffic continues to climb, with recent International Air Transport Association (IATA) figures cited by AerFin showing a 5.3 percent year-over-year increase globally. To meet this demand amidst the delivery gap, airlines must keep older aircraft in service, which inherently drives up maintenance activity, parts consumption, and workscope escalation.
A full engine overhaul represents a massive capital investment that many airlines are reluctant to make on aging assets. According to AerFin’s data, a full shop visit for a CFM56-7B, one of the most common commercial engines powering the Boeing 737 NG, currently costs between $5 million and $7 million. Even a limited performance restoration on this engine type approaches $3.5 million. For airlines already committed to spending billions on delayed new aircraft, funding second or third heavy shop visits for legacy engines is financially unviable.
Targeted Quick-Turn Solutions
Instead of full overhauls that effectively “reset the clock” on an engine’s lifespan, operators are opting for “quick-turn” or “hospital shop” visits. These targeted maintenance events focus strictly on what is absolutely necessary to keep the engine safely on-wing.
A core component of this strategy is the module swap. Operators are increasingly replacing Life Limited Parts (LLP)-expired modules with green-time units that still possess approved flying hours. In his industry outlook, Chalise notes that this method treats the engine as a continued-time asset, extracting maximum remaining value at the lowest possible cost and turnaround time.
“Module swaps are an effective short-term solution to buy time until OEM deliveries stabilize.”

The “Green-Time” Economy and Material Supply
The Role of Agile MRO Providers
Smaller, agile Maintenance, Repair, and Overhaul (MRO) providers are uniquely positioned to handle this targeted workscope efficiently, as they do not carry the massive overhead costs associated with full overhaul programs. AerFin, a global aviation asset specialist, has tailored its operations to meet this specific demand.
The company operates a state-of-the-art 116,000-square-foot facility in Caerphilly, Wales, UK. The facility, which is EASA, CAA, and FAA Part 145-approved, features 25 maintenance bays and has the capacity to run eight engine lines simultaneously. AerFin currently provides quick-turn services for highly utilized engine platforms, including the CFM56, CF34-8, and RB211, and plans to expand its capabilities to include the V2500 platform in 2026.
Securing the Supply Chain
While MRO Lite offers immediate financial relief, Chalise highlights a critical forward-looking vulnerability: the finite supply of green-time modules. If the entire industry pivots to module swaps, the availability of Used Serviceable Material (USM) could become a new bottleneck.
To insulate its customers from this supply chain risk, AerFin has aggressively expanded its material access. According to the company’s release, AerFin has acquired 104 engines since 2021 to ensure a reliable supply of green-time modules. This scale has allowed the company to successfully complete over 100 Engine MRO Lite services since the program’s launch in May 2021.
AirPro News analysis
We observe that the rapid adoption of MRO Lite strategies underscores a fundamental shift in how airlines manage late-life assets. While module swaps and quick-turn maintenance are highly effective stopgaps, they are not a permanent substitute for actual fleet renewal. As the industry continues to consume green-time engines, the premium on high-quality Used Serviceable Material (USM) will inevitably rise, potentially squeezing the profit margins of the very cost-saving measures airlines are currently relying on.
Furthermore, this trend requires careful navigation of lease return conditions. Lessors and operators must collaborate closely, as quick-turn maintenance alters the traditional lifecycle tracking and residual value of engine assets. Once OEM deliveries finally catch up and the market normalizes, we anticipate a recalibration of the MRO sector. However, the proven cost-efficiency and sustainability benefits of module swaps may permanently alter heavy maintenance schedules for legacy platforms.
Frequently Asked Questions
What is “MRO Lite”?
MRO Lite refers to targeted, quick-turn maintenance strategies, such as module swaps and hospital shop visits, designed to keep aircraft engines safely operational without the need for a full, expensive overhaul.
Why are airlines avoiding full engine overhauls?
Due to delays in new aircraft deliveries, airlines are forced to fly older planes longer. A full overhaul on an aging engine (like the CFM56-7B) can cost up to $7 million. Airlines prefer to avoid this massive capital expenditure on older assets by using cheaper, targeted maintenance.
What are “green-time” modules?
Green-time modules are partially used engine components that still have a significant number of approved flying hours or cycles remaining before they require replacement or overhaul.
