1. Introduction — Beyond aftermarket revenues: the lifecycle economics of propulsion

The commercial aircraft engine industry operates under a business model unlike almost any other industrial sector.

Before the first engine enters airline service, manufacturers must commit billions of dollars to:

• research and development;
• advanced materials;
• testing;
• certification;
• industrial preparation;
• production capability.

The return on this investment does not come immediately.

A commercial engine programme is a long-cycle industrial commitment. A propulsion system may remain in service for 25 to 40 years, during which the manufacturer remains responsible for supporting performance, reliability and fleet availability.

The traditional economic logic of the sector can be summarized as:

The engine sale creates the installed base; the aftermarket creates the economic return.

Maintenance, spare parts, repairs, upgrades and long-term service agreements generate recurring revenues that allow manufacturers to recover the investments made years earlier.

This economic model is now at the centre of a strategic debate.

At the 2026 Farnborough International Airshow, Airbus and engine manufacturers discussed whether the traditional distribution of value between aircraft manufacturers and propulsion suppliers remains appropriate for future aircraft programmes.

According to Reuters on July 24, 2026, Safran CEO Olivier Andriès argued that any future airframer–engine manufacturer business model must be “holistic.”

The significance of this word is that it links two elements often considered separately: risk and reward.

A future business model cannot focus only on the distribution of aftermarket revenues. It must also consider who contributes to and carries:

• research and development investment;
• certification uncertainty;
• technology maturity uncertainty;
• industrial execution challenges;
• long-term durability and reliability exposure.

The strategic question is therefore not simply who should receive a share of future maintenance revenues?

The deeper question is who should finance the investments and absorb the uncertainties that make those revenues possible?

This is the industrial meaning behind the word “holistic”: aligning investment, uncertainty exposure and lifecycle returns.

2. The commercial engine business model: investing first, recovering later

A modern commercial turbofan is among the most complex industrial products ever developed.

A new engine programme requires advances in:

• aerodynamics;
• high-temperature materials;
• combustion systems;
• digital control systems;
• manufacturing processes;
• testing methods.

Although programme economics remain confidential, industry experience indicates that a clean-sheet commercial engine requires several billion dollars of investment before reaching significant production revenues.

Typical characteristics include:

The manufacturer commits this capital long before knowing whether:

• the aircraft programme will achieve expected production volume;
• the technology will deliver targeted performance;
• industrial processes will mature as planned;
• the fleet will achieve expected durability and reliability levels.

This creates a unique industrial exposure.

An engine manufacturer is not simply selling hardware.

It is making a decades-long investment decision based on assumptions about:

• market size;
• technology maturity;
• industrial execution;
• operational performance.

The economic model depends on these assumptions proving broadly correct over the entire programme lifecycle.

3. The economic role of the aftermarket

The importance of aftermarket activities is often misunderstood.

Aftermarket revenues are not simply an additional profit stream generated after the original equipment sale.

They are the mechanism through which manufacturers recover the investments and uncertainties assumed during the earlier phases of the programme.

The installed fleet generates demand for:

• scheduled shop visits;
• spare parts;
• life-limited components;
• repairs;
• engine health monitoring;
• performance restoration;
• technical support.

A successful engine programme therefore depends on three conditions:

1. The aircraft programme achieves sufficient production volume.
2. The engine delivers the expected operational performance and durability.
3. The manufacturer can support the fleet efficiently throughout its service life.

Failure in any one of these areas can significantly reduce the expected economic return.

A technically successful engine can therefore still generate disappointing financial results if:

• the aircraft fleet is smaller than expected;
• production costs exceed assumptions;
• reliability performance requires excessive support activity.

4. A framework for understanding engine programme uncertainty

The word risk in the engine business covers several different realities.

A rigorous analysis must distinguish between:

1. Source of uncertainty — where the uncertainty originates during programme development.
2. Materialization — how that uncertainty later becomes visible during the programme.
3. Economic consequence — how value is ultimately affected.

Although the economic consequences may appear at different stages of a programme’s life, the underlying uncertainties are generally assumed much earlier, when the manufacturer commits to developing a new engine.

The relationship can be summarized as follows:

The economic consequence does not arise directly from the uncertainty itself.

Rather, it appears when the underlying assumptions made during programme development prove to be only partially correct.

For example:

• Aircraft market assumptions become an economic issue if the installed fleet is too small to recover the original investment.
• Technology and industrial maturity become economic issues if industrialization proves more difficult than anticipated, requiring additional engineering work, manufacturing improvements and customer support.
• Durability assumptions become economic issues if components fail to achieve the expected in-service performance, resulting in additional maintenance and support obligations.

This distinction is essential because uncertainties are generally assumed during development, while their economic consequences may not become visible until years later. This lifecycle perspective is fundamental to understanding why investment, uncertainty and long-term returns are inseparable in the commercial engine business.

5. Lifecycle exposure #1 — When aircraft demand falls below the assumptions supporting the investment case

Airbus A380: when the expected market does not materialize

The first way an engine manufacturer can lose economic value is through market assumptions made at the launch of a programme.

Unlike technical uncertainties, this source of exposure is not related to the engine itself. It stems from the assumption that aircraft demand will be sufficient to generate the installed fleet required to recover the initial investment.

The Airbus A380 provides one of the clearest examples.

Two dedicated propulsion solutions were developed:

• Rolls-Royce Trent 900;
• Engine Alliance GP7200, developed by GE Aerospace and Pratt & Whitney.

Both programmes required significant investment based on the expectation that the very-large-aircraft market would support a large installed fleet.

For an engine manufacturer, aircraft production volume is a fundamental economic driver.

The investments made during programme development are recovered over decades through:

• production volumes;
• spare parts demand;
• maintenance activity;
• fleet support.

A large installed base provides the scale necessary to amortize:

• research and development expenditure;
• industrial preparation;
• production capability;
• support infrastructure.

However, the commercial environment evolved differently from initial forecasts.

Airbus ultimately delivered 251 production A380 aircraft.

The aircraft itself was technically successful, but the market opportunity proved significantly smaller than originally anticipated.

Neither Rolls-Royce nor Engine Alliance has publicly disclosed the detailed profitability of their respective A380 engine programmes.

However, from an industrial economics perspective, the limited production volume reduced the opportunity to recover the original development and industrial investments over the fleet size initially expected.

The A380 therefore illustrates a fundamental source of uncertainty: the possibility that the market assumptions underpinning the original investment case ultimately prove too optimistic.

The issue was not:

• engine safety;
• certification failure;
• technology breakdown.

The issue was that the expected market foundation required to support the original investment case was never achieved.

The lesson for future propulsion programmes is significant:

Even a technically successful engine programme can generate insufficient economic return if the aircraft market does not create the expected installed base.

6. Lifecycle exposure #2 — Technology maturity and industrial execution as sources of uncertainty

Pratt & Whitney GTF: when development assumptions prove more demanding than expected

The second major source of uncertainty originates during programme development, when a manufacturer introduces a new propulsion architecture together with new manufacturing processes and industrial capabilities.

New propulsion technologies can create significant value for airlines through:

• lower fuel consumption;
• reduced emissions;
• lower noise;
• improved operating economics.

However, developing an advanced engine also requires assumptions regarding:

• technology maturity;
• component design;
• manufacturing processes;
• production capability;
• supply chain robustness.

The Pratt & Whitney PW1100G-JM Geared Turbofan (GTF) is a clear example.

The GTF represented one of the most significant propulsion architecture changes introduced in the narrowbody market for decades.

Its geared architecture allows the fan and the low-pressure turbine to operate at different speeds, improving propulsive efficiency compared with conventional turbofan designs.

The commercial opportunity was considerable.

The Airbus A320neo family became one of the most successful aircraft programmes in aviation history, with more than 11,000 aircraft ordered.

For an engine manufacturer, this represented an attractive economic environment:

• a large installed fleet;
• strong aircraft demand;
• decades of potential aftermarket activity.

However, the GTF also demonstrated a fundamental characteristic of the propulsion business:

A successful aircraft programme does not eliminate the uncertainties assumed during engine development.

The powdered-metal issue: from manufacturing challenge to global fleet impact

In 2023, Pratt & Whitney identified a manufacturing quality issue involving powdered-metal material used in certain engine components.

The issue was not a failure of the fundamental geared turbofan concept.

Rather, it reflected manufacturing and component-quality issues whose consequences became visible only after a large fleet had entered airline service.

The consequences affected airlines operating A320neo-family aircraft equipped with GTF engines.

During the peak period of the recovery programme:

• hundreds of aircraft were temporarily unavailable;
• RTX indicated that the number of aircraft unavailable due to GTF inspections and removals could exceed 600 aircraft at certain points during the fleet management campaign;
• thousands of engines required inspections or accelerated shop visits;
• airlines experienced reduced fleet availability and operational disruption.

The scale of the impact was amplified by the size of the installed fleet.

A technical issue affecting a limited number of engines can normally be managed through standard maintenance processes.

A technical issue affecting thousands of engines becomes a global industrial event requiring:

• additional engineering resources;
• expanded maintenance capacity;
• spare engine availability;
• extensive logistics coordination.

Financial impact: the economic consequence of industrial recovery actions

RTX estimated the financial impact of the GTF fleet management plan at approximately:

$6–7 billion in cumulative pre-tax charges.

This figure represents the overall economic impact of managing the fleet issue.

It includes several categories of costs:

The important industrial lesson is not only the size of the financial exposure, but also where the exposure originated.

The Airbus A320neo programme remained commercially successful.

Aircraft demand remained strong.

The economic consequences of the propulsion issue were primarily absorbed by the engine manufacturer.

The GTF therefore illustrates how assumptions made during development regarding technology maturity and industrial readiness can later translate into substantial operational and financial consequences once the engine enters large-scale airline service.

The technology itself created significant value potential.

The challenge was ensuring that manufacturing robustness, industrial maturity and fleet support capability evolved to the level assumed when the programme was launched.

7. Lifecycle exposure #3 — In-service durability performance versus initial expectations

Rolls-Royce Trent 1000: when operational durability differs from programme expectations

The third major source of exposure becomes visible once the engine enters airline operation.

Certification confirms that an engine complies with regulatory safety and performance requirements at entry into service.

However, certification cannot guarantee that every component will achieve the durability and maintenance performance anticipated during development after thousands of flight cycles in real airline operations.

The Rolls-Royce Trent 1000 illustrates the economic consequences when durability assumptions made during development prove optimistic in service.

The Boeing 787 Dreamliner became one of the most successful widebody aircraft programmes ever launched.

Rolls-Royce was one of the two major engine suppliers for the aircraft, alongside General Electric.

The Trent 1000 was designed to provide:

• high efficiency;
• competitive fuel consumption;
• strong operating economics for long-range missions.

However, during airline operations, several durability issues emerged involving engine components, particularly in compressor and turbine areas.

These issues required extensive corrective actions and fleet support measures.

Operational consequences for airlines

The Trent 1000 challenges affected airline operations through:

• additional inspections;
• accelerated shop visits;
• modification programmes;
• increased spare engine requirements;
• reduced aircraft availability.

Several operators experienced:

• temporary aircraft groundings;
• schedule disruption;
• the need for additional capacity solutions while engines underwent corrective maintenance.

The number of affected aircraft varied over time depending on:

• inspection requirements;
• modification status;
• airline fleet composition;
• operational decisions.

The challenge was not whether the engine had achieved certification approval.

The challenge was whether the durability targets assumed during development would be achieved throughout commercial operation.

Financial consequences for Rolls-Royce

Rolls-Royce reported significant financial impacts in Civil Aerospace related to Trent 1000 and other in-service engine challenges.

The costs included:

• additional maintenance activity;
• technical remediation;
• customer support;
• increased aftermarket requirements;
• operational recovery measures.

The Trent 1000 experience contributed to a broader strategic reassessment at Rolls-Royce regarding:

• lifecycle profitability;
• fleet support obligations;
• aftermarket economics;
• the balance between initial engine sales and long-term service commitments.

The Trent 1000 demonstrates how durability assumptions made during development can generate substantial long-term economic consequences when they are not fully achieved in airline service.

For engine manufacturers, economic exposure continues throughout the operating life of the engine.

8. Three examples, three different sources of economic exposure

The three cases demonstrate that the major economic exposures in the commercial engine business originate during programme development, even though their financial consequences may become visible at very different moments.

The common element is that the underlying assumptions are established before entry into service, while their consequences may emerge years later.

The nature of these consequences differs:

• Aircraft market assumptions are validated progressively as production develops.
• Technology and industrial assumptions are tested during entry into service and production ramp-up.
• Durability assumptions are validated only after years of airline operation.

This perspective better explains why engine manufacturers remain economically exposed long after development has been completed.

It also reflects the “holistic” approach advocated by Olivier Andriès: the risks accepted during development may generate consequences throughout the programme’s entire economic life.

9. Why Safran says the future model must be “holistic”

The future generation of commercial aircraft will require propulsion technologies significantly more advanced than today’s engines.

Potential developments include:

• open-fan propulsion;
• advanced composite structures;
• new materials;
• hybrid-electric systems;
• deeper aircraft-engine integration;
• new manufacturing processes.

These technologies could deliver major improvements in:

• fuel efficiency;
• emissions reduction;
• operating economics.

However, they will also require:

• higher research and development spending;
• longer technology maturation periods;
• more complex industrial systems;
• greater uncertainty before commercial maturity is achieved.

This is the core meaning of Olivier Andriès’ statement.

A future business model cannot consider only who receives aftermarket revenues.

It must consider the complete economic equation.

The argument behind a “holistic” model is therefore not simply about commercial negotiations or aftermarket revenue sharing.

It is about ensuring that those who participate in the value created by future propulsion programmes also participate in the investments and uncertainties required to create that value.

The underlying principle is straightforward:

Reward should be considered together with risk exposure.

10. Towards a new industrial contract between airframers and engine manufacturers?

Future aircraft programmes will require unprecedented levels of cooperation between aircraft manufacturers and propulsion suppliers.

The traditional relationship—where one company develops the aircraft and another provides the engine—may evolve as propulsion becomes increasingly connected with:

• aircraft architecture;
• environmental objectives;
• operational performance targets;
• digital systems;
• overall aircraft efficiency.

The strategic question will no longer be limited to: Which company develops the most efficient engine?

It will also become:  How should investment, risk and reward be distributed among the partners developing the next generation of aircraft propulsion systems?

This is why Olivier Andriès’ use of the word holistic is significant.

The term describes a broader industrial approach:

• recognising who invests;
• recognising who carries uncertainty;
• recognising who supports the product throughout its operational life;
• recognising how economic returns should be distributed when the programme succeeds.

Conclusion — The future of propulsion is a development risk-sharing challenge

The commercial aircraft engine business has always been based on long-term commitments.

Manufacturers invest billions before receiving significant returns and remain responsible for supporting their products throughout decades of operation.

The Airbus A380 demonstrated that optimistic market assumptions may prevent the original industrial investment from being fully recovered.

The Pratt & Whitney GTF demonstrated that technology and industrial assumptions made during development can create major economic exposure when large-scale industrialisation proves more difficult than expected.

The Rolls-Royce Trent 1000 demonstrated that durability assumptions established during development may require years of airline operation before they can be fully validated.

Together, these examples explain why Safran argues that the future airframer-engine manufacturer relationship must be holistic.

The debate is not only about who receives aftermarket revenues.

It is about more fundamental industrial questions:

• Who finances innovation?
• Who carries development uncertainty?
• Who supports the product throughout its operational life?
• How should the rewards of success be shared when a programme reaches maturity?

For the next generation of aircraft propulsion, the answer will determine not only the commercial relationship between airframers and engine manufacturers, but also the industry’s ability to finance the technological breakthroughs required for aviation’s future.
