THE ENGINE BOTTLENECK

Why the engine and aftermarket ecosystem may determine how much of aviation's growth can actually take flight.

EXECUTIVE PERSPECTIVE

The aircraft may be ordered. The capacity may be needed. But can the engine ecosystem keep up?

Commercial aviation continues to expand its ambitions.

Airlines are ordering aircraft. Lessors are deploying capital. Fleets are getting larger. New markets are developing.

But beneath that growth, another constraint is becoming increasingly visible:

The ability to keep aircraft flying depends on the availability of engines, maintenance capacity, material and technical expertise.

The engine is no longer simply one component of an aircraft.

It is increasingly becoming a strategic asset within the aircraft lifecycle.

Recent developments across the industry illustrate the shift.

Turkish Airlines and CFM have signed an agreement covering more than 300 new LEAP-1B engines, while long-term services will support a fleet of more than 600 LEAP-1B engines operated by Turkish Airlines and AJet. The agreement also supports the development of the airline's future engine MRO capability in Türkiye.

At the same time, United Airlines and FTAI have expanded their engine exchange relationship to CFM56-7B engines, using serviceable replacement engines to reduce traditional shop-visit downtime while feeding unserviceable engines into FTAI's MRO network.

These are not isolated developments.

They are signals of a larger transformation:

As aircraft become increasingly valuable because they are scarce, the resources required to keep them flying become equally strategic.

5 KEY SIGNALS

01 | ENGINE ACCESS IS BECOMING PART OF FLEET STRATEGY

Turkish Airlines' agreement with CFM is a powerful example.

The airline's commitment covers more than 300 LEAP-1B engines, including spares, for up to 150 Boeing 737 MAX aircraft. More significantly, its long-term services arrangement covers more than 600 LEAP-1B engines across Turkish Airlines and AJet, including engines already delivered, engines associated with leased aircraft and potential options.

This demonstrates that an airline's fleet strategy increasingly extends beyond the aircraft order itself.

The question becomes:

How will the engines be supported throughout their lifecycle?

The agreement also includes material services supporting a future engine MRO facility in Türkiye.

AERODESK SIGNAL

The engine is becoming part of the fleet strategy — not merely a component of the aircraft.

For airlines planning significant fleet expansion, securing long-term engine support can be almost as strategic as securing the aircraft themselves.

02 | ENGINE EXCHANGE IS CHANGING THE MAINTENANCE EQUATION

United Airlines and FTAI are taking a different approach.

Their expanded Maintenance, Repair and Exchange program for CFM56-7B engines allows FTAI to provide a serviceable engine ahead of a scheduled removal while acquiring the airline's unserviceable engine in exchange.

The objective is straightforward:

Keep the aircraft flying while shifting the shop-visit burden into an integrated engine-management model.

FTAI then feeds the acquired engines into its MRO network.

This creates a circular relationship between:

Engine ownership → exchange → MRO → material recovery → future availability.

The model also shows why engine assets themselves can become strategic sources of flexibility.

AERODESK SIGNAL

The value of an engine is increasingly tied not only to its condition, but to the speed at which it can be returned to service.

That makes availability, exchange capability and turnaround time increasingly important commercial variables.

03 | MRO CAPACITY IS EXPANDING — BECAUSE DEMAND IS COMING

The industry is preparing for a major increase in engine aftermarket activity.

CFM says it is expanding its open MRO ecosystem in anticipation of the ramp-up in LEAP shop visits. The company has added Premier MRO providers and is increasing internal shop and test-cell capacity, while also investing in repairs, spare-parts inventory and supplier performance.

The network is becoming increasingly global.

And the latest developments reinforce that trend.

FL Technics Engine Services has partnered with Lufthansa Group's Group Engine Management for CFM56 repair and maintenance work in Lithuania. ITP Aero Mexico has received FAA authorization to test CFM56-5A/-7B and LEAP-1A/-1B engines from its Querétaro test facility.

Meanwhile, CFM's installed base remains enormous: more than 23,000 CFM56 engines are still in service, supported by an open MRO ecosystem of approximately 40 shops globally.

AERODESK SIGNAL

MRO capacity is no longer simply following fleet growth. It is becoming infrastructure that enables fleet growth.

Where engine capacity is available, aircraft can remain productive.

Where it is constrained, aircraft availability can become constrained as well.

04 | THE ENGINE ITSELF IS BECOMING AN INVESTMENT ASSET

The financial market is also recognizing the strategic value of engines.

GFH Financial Group has joined the Bridgepoint/AIP Capital engine-leasing venture, which is targeting a commercial engine portfolio valued at more than $1 billion. The venture has already acquired LEAP-1B engines and plans to attract additional institutional and private-wealth capital.

This is significant because it shows that engine ownership is increasingly being viewed through an investment lens.

An engine can generate value through:

• Leasing

• Exchange

• MRO

• Parts recovery

• USM

• Residual value

• Lifecycle management

At the same time, the aftermarket is creating value from engines that are no longer economically viable as complete units.

Prime Air, for example, acquired a CFM56-5B engine for disassembly, with the resulting USM destined to support airline and MRO customers.

AERODESK SIGNAL

The engine lifecycle is becoming an investable ecosystem.

Value can exist at multiple stages — from serviceable engine to shop visit, exchange, teardown and material recovery.

05 | REGIONAL ENGINE CAPABILITY IS BECOMING STRATEGIC

One of the most interesting developments is happening geographically.

ITP Aero Mexico's FAA authorization to test CFM56-5A/-7B and LEAP-1A/-1B engines in Querétaro is more than a technical approval. It represents another step toward developing engine capability closer to the fleets that require it.

The same pattern is appearing elsewhere.

FTAI has been expanding its Asia-Pacific engine strategy, including collaboration with GMF AeroAsia around CFM56-5B and -7B engines and future capabilities. The partnership includes guaranteed capacity for FTAI over five years and plans for deeper module and piece-part capabilities.

This matters because geography affects:

Turnaround time → logistics → transportation costs → AOG response → aircraft availability.

AERODESK SIGNAL

Engine MRO is becoming increasingly regional — and proximity itself can become a competitive advantage.

The next generation of aviation infrastructure may not simply be about where aircraft are based.

It may also be about where their engines can be supported.

OPPORTUNITY RADAR

If engine availability becomes a strategic constraint, several commercial opportunities become more important:

ENGINE MRO

Additional shop capacity, specialized repairs and faster turnaround.

SPARE ENGINES

Access to serviceable engines can protect aircraft utilization.

ENGINE EXCHANGE

Alternative models can reduce downtime and improve maintenance predictability.

MODULE & COMPONENT CAPABILITY

More specialized capability can keep engines moving through the ecosystem.

USM

Teardown and material recovery can create value from mature engine assets.

ENGINE LEASING

Capital is increasingly being deployed directly into engine assets.

REGIONAL MRO

Strategic locations can reduce logistics and turnaround pressures.

TECHNICAL SUPPORT

The growth of the installed base creates continued demand for engineering, technical and field-support capability.

THE AERODESK VIEW

THE ENGINE IS MOVING FROM COMPONENT TO CONTROL POINT

The five signals point toward the same conclusion.

Airlines need aircraft.

But aircraft only create capacity when their engines are available, serviceable and supported.

That creates a chain:

Aircraft → Engine → MRO → Parts → Material → Technical Capacity → Aircraft Availability

A weakness anywhere in that chain can affect the entire asset.

This is why the engine aftermarket deserves to be viewed as more than a maintenance category.

It is increasingly part of the commercial infrastructure of aviation.

CFM's continued investment in its MRO ecosystem, the emergence of engine-exchange models, growing engine-leasing portfolios, increasing USM activity and new regional capabilities all point toward a market where access to engine resources can influence how effectively aircraft assets are utilized. 

And the broader services market reinforces the trend.

Airbus now projects the aviation services market could reach approximately $420 billion by 2045, while the industry will require another 2.44 million aviation workers over the next two decades, including approximately 730,000 maintenance professionals.

The implication is important:

Aviation's growth story increasingly depends on the ecosystem behind the aircraft.

BOTTOM LINE

Aviation's next growth cycle may not be limited by the number of aircraft that airlines can order.

It may increasingly be determined by how effectively the industry can keep those aircraft flying.

Engines sit at the center of that equation.

The companies positioned to support, finance, lease, repair, exchange and recover value from engines may therefore become increasingly important to the broader aviation ecosystem.

From aircraft growth to engine availability.

The next aviation opportunity may be found in everything that keeps the aircraft flying.
