GE Aerospace
The jet-engine maker that sells the engine at a low margin, then supplies the approved parts and overhauls for as long as the aircraft flies.
The scores
Growth3/4 ↑
Fast and organic, but the record at this rate is two years and GE's own guide halves the second half.
Business quality4/4 →
Both attackers concede the position in their own filings, and it survived the pandemic and a live durability problem.
Financial position3/4 →
Net borrowings near one year of guided cash, no maturity wall - but the plan now needs new debt for an $11.75B purchase.
Execution record3/4 ↑
Eight beats and two raises, but the largest capital decision it has made is three days old and closes in 2027.
Per share capture4/4 →
Count down 1.07% in six months, $4.22B of buybacks against modest issuance, the acquisition paid in cash rather than stock.
Potential3/4 →
A bounded upside that is substantially contracted - $178.71B of filed services orders - rather than transformative or merely expected.
Risk profile3/4 →
One serious dependency, disclosed and survivable: $36.2B of old insurance promises that may need cash, with no named customer concentration.
Valuation2/4 →
The price pays for the plan and the 2028 margin turn beyond it; little is left if that only half-happens.
Evidence quality3/4 →
Central facts are filed and corroborated from rivals' filings, but the forward margin claim is management's and verifiable nowhere.
The Verdict
We rate GE Aerospace neutral. It sells jet engines at a low margin, then supplies their approved parts and overhauls for as long as the aircraft flies, and most of its revenue is that aftermarket. The business is strong and well protected, better evidenced than the market's own reasons for it. But the price is full: it already assumes a margin recovery that management dates years ahead and no filing carries, so buyers pay up front for it. The view hinges on whether sales keep growing quickly while the company's own forecast says growth slows. It is a superb business, with no room left if the recovery is late.
The long caseAir travel keeps growing, and every engine flying must come in for parts and overhauls on a schedule airlines do not set, so GE earns from each engine for decades.
The evidence under this - 8 claims
- None of it appears in a filing. GE publishes no margin by engine programme, no LEAP services margin and no GE9X loss figure, so there is nothing to check the 2028 turn against and nothing to notice if it slips.
- 2028 is two years beyond the guidance horizon. The same management declined to raise guidance in April 2026 on a strong first quarter, citing uncertainty it could not see through one quarter ahead.
- The chief financial officer also said the external channel will take about 30% of LEAP services by 2030. A third of the work moving to third-party shops is a margin mix change running the other way, and GE publishes no attach rate that would let a reader weigh the two.
- The company has said LEAP services broke even only in 2024, so the starting point of the recovery is recent and the slope is entirely asserted.
- Free cash flow conversion above 100% of adjusted net income is not a steady state and management says it will normalise, so the denominator is currently flattered - which makes the multiple look better than the underlying one, not worse.
- The 2030 estimate rests on five contributors, against twelve for 2028. A four-year-out consensus from five people is a thin base for any statement about what is priced.
- The shares are 16.6% below their 52-week high and the 14-day relative strength index is 34.9, so some of the premium has already come out; the multiple is not being struck at the top.
- GE has no usable multiple history to compare this against - the research pack's prior-year medians span years when the company also owned GE HealthCare and GE Vernova.
- The company saying it is the company trying hardest to break it: HEICO exists to sell approved non-OEM parts, has roughly 20,000 approvals and adds 400 to 550 a year.
- The word is 'historically'. HEICO's own filing calls the approval process a barrier to entry rather than a wall, and says the rate at which competitors can bring products to market is limited rather than zero.
- GE is itself widening the channel: its 10-K says it sells spare parts to third-party overhaul shops and licenses maintenance technology to them, so the sole-source position is partly one GE chooses how far to enforce.
- The same filing names a loss of OEM authorisation as a principal risk, which says the licence is revocable and therefore that it is a commercial relationship rather than a permanent tax.
- StandardAero also reports that its authorisations have in the past been renewed or extended at expiration, so in practice the engine maker has not used the leverage the licence gives it.
- It competes for overhaul labour, which is real revenue GE loses when a shop visit goes elsewhere - the royalty does not make GE indifferent to who performs the work.
- Management gave the reason unprompted: the second half of 2025 was $3B larger than the first half of 2025, so the comparison base is materially harder rather than the run rate being lower.
- The chief financial officer said more than 95% of Q3 2026 spare-parts revenue was already in backlog and that engines off wing plus planned removals exceed the full-year shop-visit guide by over 40%, which is visibility a conservative guide would carry.
- GE has beaten in each of the last eight quarters, so a guide that implies deceleration has a record of being beaten.
- The Q3 call gave the reason for the 14% fall: working capital was a use, as receivables grew with the timing of services billings and a larger balance due from airframers, partly offset by contract assets. That is timing rather than lower earnings, but it is management's account and the receivable has to be collected in the fourth quarter for the guide to hold.
- 2026-10-20editedThe Q3 2026 print resolved the second-half test; the estimate is re-struck on the October guide for the fourth quarter alone.
- 2026-10-21editedThe Q3 call explained the free cash flow fall as receivables timing; counter-evidence added, estimate unchanged
The company
An airliner is sold with its engines, and GE Aerospace makes its money on them mostly later. It has about 50,000 commercial and 30,000 military engines in service, and every one needs parts and overhauls for as long as it flies.
Its best-selling engine for single-aisle jets, the LEAP, is built by CFM International, a 50-50 venture with Safran, so Safran takes half the economics of that franchise.
The evidence under this - 2 claims
How it makes money
The engine is the entry ticket; the parts are the business. Spare parts alone are about 40% of revenue, and $178.71B of the $210.79B of contracted work at June was service rather than engines.
Even independent shops that overhaul GE engines pay GE for the right, through a licence fee and sometimes royalties.
The evidence under this - 3 claims
- It exists only on the call. The 10-K and 10-Q disaggregate revenue into equipment and services and never split services into parts and labour, so the 40% cannot be checked against any filed table.
- Management gave the figure while walking back a stronger intra-quarter number it called unsustainable, so the context was a correction rather than a disclosure.
- 2026-10-20editedRe-sourced to the Q3 2026 10-Q: contracted work rose to $212.08B at 30 September 2026.
- The same filing names a loss of OEM authorisation as a principal risk, which says the licence is revocable and therefore that it is a commercial relationship rather than a permanent tax.
- StandardAero also reports that its authorisations have in the past been renewed or extended at expiration, so in practice the engine maker has not used the leverage the licence gives it.
- It competes for overhaul labour, which is real revenue GE loses when a shop visit goes elsewhere - the royalty does not make GE indifferent to who performs the work.
Where the money comes from, stream by stream
| Stream | Share of sales (H1 2026) | How it earns it |
|---|---|---|
| Commercial engine services | 55.4% | Spare parts, overhauls and service agreements on the installed commercial fleet, including licence fees from independent shops. |
| Commercial engines | 17.1% | New commercial jet engines sold to planemakers and airlines, at a low or negative margin. |
| Defense & Propulsion equipment | 13.0% | Military engines, aeroderivative units and propulsion components, largely funded by US and allied defence budgets. |
| Defense & Propulsion services | 12.8% | Spares, repairs and support for military engines and other propulsion products. |
| Run-off insurance | 5.8% | Premiums and investment income on a closed book of long-term care and annuity reinsurance, excluded from adjusted revenue. |
Who runs it
Larry Culp, who ran Danaher for fourteen years, took over GE in 2018, broke it into three companies and now runs the aerospace business that remained. Insiders own well under 1% of the shares, mostly Culp's. His bonus rides on sales growth, profit and cash, and his long-term shares on three years of earnings per share and cash, adjusted for how the stock does against other industrials. Nothing pays on return on capital.
The evidence under this - 3 claims
- Every metric is a measure GE defines itself (C18): operating profit and free cash flow exclude what the company chooses, so the plan pays on the same non-GAAP figures it guides to.
- Nothing pays on return on capital, so the $11.75B CPP purchase (C16) costs the plan nothing unless it dents three-year EPS or cash.
Why it wins, and who could beat it
Why customers come back
Every replacement part fitted to a jet engine needs a government approval for that engine, and every overhaul follows a manual the engine's designer writes. GE holds both, and an airline cannot change engines halfway through an aircraft's life.
The evidence comes from rivals' own filings. HEICO, which makes approved copies, says engine makers have historically been the sole source of substantially all replacement parts. The world's largest independent overhaul shop works under a GE licence and pays GE for it.
The evidence under this - 3 claims
- The company saying it is the company trying hardest to break it: HEICO exists to sell approved non-OEM parts, has roughly 20,000 approvals and adds 400 to 550 a year.
- The word is 'historically'. HEICO's own filing calls the approval process a barrier to entry rather than a wall, and says the rate at which competitors can bring products to market is limited rather than zero.
- GE is itself widening the channel: its 10-K says it sells spare parts to third-party overhaul shops and licenses maintenance technology to them, so the sole-source position is partly one GE chooses how far to enforce.
- The same filing names a loss of OEM authorisation as a principal risk, which says the licence is revocable and therefore that it is a commercial relationship rather than a permanent tax.
- StandardAero also reports that its authorisations have in the past been renewed or extended at expiration, so in practice the engine maker has not used the leverage the licence gives it.
- It competes for overhaul labour, which is real revenue GE loses when a shop visit goes elsewhere - the royalty does not make GE indifferent to who performs the work.
The threat
The copies are coming, slowly. HEICO holds about 20,000 approved parts across all engines, adds 400 to 550 a year, and sells them cheaper than the maker. And thirty years of parts only begins if GE wins the engine order first: Pratt & Whitney competes for the same single-aisle Airbus jets.

How big it could get
How big this could get
Boeing expects the world's airliner fleet to grow nearly 80%, to more than 50,000 aircraft by 2045, and support and services to be worth $4.9 trillion over those twenty years. Those are a planemaker's forecasts.
The nearer prize is already flying. GE says 30% of its older CFM56 engines have not had a first overhaul and two-thirds have not had a second, and 70% of its large GE90 engines still await a second.
The evidence under this - 3 claims
- Boeing is forecasting the market it sells into, and the forecast is published at an airshow. It is outside GE, not outside the industry.
- The World Bank's measured count of air transport passengers carried was 4.269 billion in 2023, the latest year published, still 4.2% below the 4.456 billion of 2019 - so the measured series had not regained its pre-pandemic peak when the forecast of doubling was written.
- GE itself said first-half 2026 departures were roughly flat and expected only a gradual return to modest growth in the second half.
- The figure covers the whole services market - pilot and technician training, ground handling, digital tools and airframe maintenance - and GE sells none of those. The engine share of it is not disclosed and Boeing has no reason to break it out.
- It is Boeing's forecast of a market Boeing Global Services competes in, so the issuer is a rival for part of the same spend rather than a neutral measurer.
- The 728,000 technicians the same document calls for is the constraint on it: a services market that cannot be staffed is not a services market that gets billed.
- It is a call figure with no filed counterpart. GE publishes no fleet-age or shop-visit-history table, so neither the 30% nor the two-thirds can be checked.
- The same call flagged airline financial pressure from higher fuel prices, which is the condition under which retirements accelerate and used parts flood the channel - the two statements sit in tension.
- Management also said there are fewer long-term service agreements on CFM56 engines than on widebodies, so a large part of this runway is work GE expects to win rather than work it has contracted.
Who has signed
Contracted work stood at $210.79B at the end of June, up 11% since December, and it counts only orders a customer cannot cancel without a real penalty. The headline deals are softer: IndiGo's agreement for more than 1,000 engines is a memorandum, not a firm order.

What growth costs
Running costs grow slower than sales, so overhead gets cheaper per dollar. But growth now comes partly from new engines sold below cost, so every extra delivery pulls the margin down until those engines come back for parts and overhauls. Research and factory spending also rise a little faster than sales.
The evidence under this - 2 claims
- Total R&D including customer and partner funding was $2.99B in 2025 (C34), about twice the line counted here, so the cost of the next engine generation is larger than the per-dollar figure shows.
- The years before 2023 include businesses since spun off, so the trend is three years long.
The last report (16 Jul)
Quarter ended June 2026, filed figures.
In the September quarter sales grew 18% and operating profit 30%, helped by the engine business: engine orders rose 49% and contracted work rose to $212B. The company raised its 2026 forecast on every line, for the second time in three months.
The one weak line was free cash flow, which fell 14% in the quarter, though it is still up 13% over nine months. To hit its new cash forecast, the fourth quarter must be a third to a half better than a year earlier.
What it did to the thesisSales growth beat the mark we set and the margin held up better than in June. Falling free cash flow was one of our warning signs, so the print neither confirmed nor broke the case. The view stays Neutral: the price still pays for a recovery no filing carries.
The quarter in detail
Sales growth from the previous quarter, filed figures. The company has restated its own history, so a quarter either side of the restatement may describe a different business; n/c marks one that does not compare.
Earnings per share $2.02 against $1.86 expected; $2.26 as filed, the gap being what the company adds back.
The evidence under this - 5 claims
- 2026-10-20editedRe-sourced to the Q3 2026 10-Q: contracted work rose to $212.08B at 30 September 2026.
- The cash guide needs a fourth quarter of free cash flow roughly a third to a half above the fourth quarter of 2025, after the third quarter fell 14%.
- The same guide implies fourth-quarter adjusted revenue growth of roughly 8% to 12% against 18% in the third quarter and 23% over nine months.
- Guidance was deliberately held in April 2026 despite a strong first quarter, then raised in July and again in October. A company that can hold and then raise twice in six months sets guidance with a wide margin, which cuts both ways for what a raise signals.
- 2026-10-20editedThe 20 October 2026 release raised the full-year guidance a second time; the 16 July figures are superseded.
- Management gave the reason unprompted: the second half of 2025 was $3B larger than the first half of 2025, so the comparison base is materially harder rather than the run rate being lower.

- None of it appears in a filing. GE publishes no margin by engine programme, no LEAP services margin and no GE9X loss figure, so there is nothing to check the 2028 turn against and nothing to notice if it slips.
- 2028 is two years beyond the guidance horizon. The same management declined to raise guidance in April 2026 on a strong first quarter, citing uncertainty it could not see through one quarter ahead.
- The chief financial officer also said the external channel will take about 30% of LEAP services by 2030. A third of the work moving to third-party shops is a margin mix change running the other way, and GE publishes no attach rate that would let a reader weigh the two.
- The company has said LEAP services broke even only in 2024, so the starting point of the recovery is recent and the slope is entirely asserted.
What management did with the money
It bought back 14.1 million shares for $4.22B in the first half and raised the quarterly dividend to $0.47 from $0.36. In September it agreed to buy Consolidated Precision Products, a castings maker, for $11.75B, a little over five quarters of its expected cash, paid with cash and new debt.
The evidence under this - 3 claims
- The $2.0B revenue, the $200M of synergies and the year-five return are GE's own projections in its own deal deck. Nothing about them is filed or audited, and no pro forma financial statement for the target exists yet.
- The accretion claim is stated after excluding one-time costs and deal-related amortisation, which is to say it is accretion to a measure that removes most of what an acquisition costs.
- 26 times profit before synergies is close to GE's own enterprise value of 28.4 times trailing profit before depreciation, so GE is paying roughly its own multiple for a foundry - and the shares fell 2.8% the session after the announcement.
- It does not close for a year. Every number in it is a 2027 estimate made in 2026, and GE has no post-separation record of integrating a purchase this size.
- The cash goes out once and over a period, not in a year: closing is expected in the second half of 2027, and GE says the purchase uses existing cash and new debt rather than a year of operating cash flow.
- GE says capital allocation plans do not change, and $17.98B of a $20B buyback authorisation remained at 30 June 2026 - so the company does not regard the deal as consuming the shareholder return.
- Net borrowings of about $8.9B against guided cash of $9.05B leave real capacity; the ratio is a way of sizing the decision, not evidence that GE cannot afford it.
The price, and where we disagree
In short. Full. A superb business, but the price already pays for its profit recovery arriving on schedule by 2028, and leaves no room if it is late.
The company's own forecast now asks for a stronger fourth quarter in cash and a slower one in sales. The full-year report in January answers it: free cash flow at or above the forecast's low end would confirm the raise, while a miss would show the September fall was the start of something.
The evidence under this - 2 claims
- Management gave the reason unprompted: the second half of 2025 was $3B larger than the first half of 2025, so the comparison base is materially harder rather than the run rate being lower.

How we read the multiple
Each year's spare cash, what is left after running and investing in the business, is about 2.5% of today's price. On the higher cash expected for 2026, a buyer pays $37 for each dollar.
For the price to look cheap:
- Spare cash would have to roughly double to reach 5% of today's price.
- Even on analysts' 2030 forecast, buyers would still pay $25 for each dollar of profit.
- So the price already assumes the margin recovery expected from 2028 arrives on time.
Against its own history. Not a fair comparison: those years include GE HealthCare and GE Vernova, since spun off, so this company's own normal cannot be read from them.
The evidence under this - 3 claims
- Free cash flow conversion above 100% of adjusted net income is not a steady state and management says it will normalise, so the denominator is currently flattered - which makes the multiple look better than the underlying one, not worse.
- The 2030 estimate rests on five contributors, against twelve for 2028. A four-year-out consensus from five people is a thin base for any statement about what is priced.
- The shares are 16.6% below their 52-week high and the 14-day relative strength index is 34.9, so some of the premium has already come out; the multiple is not being struck at the top.
- GE has no usable multiple history to compare this against - the research pack's prior-year medians span years when the company also owned GE HealthCare and GE Vernova.
- None of it appears in a filing. GE publishes no margin by engine programme, no LEAP services margin and no GE9X loss figure, so there is nothing to check the 2028 turn against and nothing to notice if it slips.

- The company has said LEAP services broke even only in 2024, so the starting point of the recovery is recent and the slope is entirely asserted.
Priced against its rivals
Only RTX sells the same thing to the same buyers as a large part of what it does. A price comparison needs at least two, so the price is judged against its own history instead.
Private or foreign rivals that cannot be priced: Rolls-Royce Holdings plc, Safran S.A. (Safran Aircraft Engines), MTU Aero Engines AG, Lufthansa Technik AG.
Where we disagree with the market
A protected business whose maintenance backlog and promised margin recovery justify paying far more than for most industrial companies.
The protection is real and better evidenced than the market's reasons, but the price already pays for a recovery no filing carries.
Analysts are 24 buy and 11 hold with no sells, and GE has beaten their estimates eight quarters running. Coverage reads its backlog and its beats; we read two rivals' filings for the moat and the second-half arithmetic for growth.
We are wrong if the September quarter's sales grow more than 12% with the margin widening: then the slowdown was caution, not the real rate.

- StandardAero also reports that its authorisations have in the past been renewed or extended at expiration, so in practice the engine maker has not used the leverage the licence gives it.
- It competes for overhaul labour, which is real revenue GE loses when a shop visit goes elsewhere - the royalty does not make GE indifferent to who performs the work.

That is timing rather than lower earnings, but it is management's account and the receivable has to be collected in the fourth quarter for the guide to hold.
- 2026-10-20editedThe Q3 2026 print resolved the second-half test; the estimate is re-struck on the October guide for the fourth quarter alone.
- 2026-10-21editedThe Q3 call explained the free cash flow fall as receivables timing; counter-evidence added, estimate unchanged
What could go wrong, and how we would know
The risks
- Copies take share. Approved outside parts and independent shops chip at the one thing the moat protects: GE's own parts in GE's own engines.
- An old insurance business. $36.20B of old insurance liabilities against $17.64B of shareholders' equity, and GE names future capital calls as a risk.
- A recovery only management promises. Better LEAP service margins and peak GE9X losses by 2028 are on a call, not in a filing.
- Parts running short. Spare-part shipments delayed for lack of material grew 20% from the quarter before, in June.
- Flat flying. Departures were roughly flat in the first half of 2026, and revenue follows flying.
The evidence under this - 7 claims
- The same filing names a loss of OEM authorisation as a principal risk, which says the licence is revocable and therefore that it is a commercial relationship rather than a permanent tax.
- StandardAero also reports that its authorisations have in the past been renewed or extended at expiration, so in practice the engine maker has not used the leverage the licence gives it.
- It competes for overhaul labour, which is real revenue GE loses when a shop visit goes elsewhere - the royalty does not make GE indifferent to who performs the work.
- A third of LEAP services performed outside GE's shops is a third of the labour margin leaving, and GE publishes no parts attach rate that would show the parts margin staying behind to replace it.
- StandardAero's own filing shows the other side of the same arrangement and names loss of an OEM authorisation as a principal risk - so the channel is GE's to control today, and GE is choosing to widen it while the aftermarket is capacity-constrained.
- GE's shops are 40% oversubscribed, so widening the external channel now is partly a response to not being able to do the work, which is a weaker reason than choosing the higher-margin half.
- None of it appears in a filing. GE publishes no margin by engine programme, no LEAP services margin and no GE9X loss figure, so there is nothing to check the 2028 turn against and nothing to notice if it slips.
- 2028 is two years beyond the guidance horizon. The same management declined to raise guidance in April 2026 on a strong first quarter, citing uncertainty it could not see through one quarter ahead.
- The chief financial officer also said the external channel will take about 30% of LEAP services by 2030. A third of the work moving to third-party shops is a margin mix change running the other way, and GE publishes no attach rate that would let a reader weigh the two.
- The company has said LEAP services broke even only in 2024, so the starting point of the recovery is recent and the slope is entirely asserted.
- The same fact is a delivery failure as well as a demand signal: GE has sold parts it cannot ship, and the delinquency grew in a quarter it was calling record output.
- It is unaudited and appears in no filing. The 10-Q describes material availability disruptions qualitatively and puts no number on the backlog of late shipments.
- The chief executive said spare-parts order growth had already normalised from an unsustainable 40% rate in the last weeks of the quarter, so the demand half of the figure was measured at a peak.
- The Q3 call confirmed delinquency rose a second quarter running, which is the 'rising again' mark the next test names; management called it a function of strong demand and said it wants to bring it down in 2027, with no figure given for the size of the backlog of late shipments.
- 2026-10-21editedThe Q3 2026 call, read on 21 October, said spare-parts delinquency grew again in the quarter; the claim now carries the second reading
- The 10-Q names the conflict in the Middle East as a risk to utilisation, prices and airline credit, and says lower shop visit, spare part and spare engine volume could follow - management's confidence and its own filed risk disclosure point different ways.
- Flat departures with services revenue up 32% means the growth is coming from deferred maintenance and material availability rather than from flying, which is a catch-up rather than a rate.
What we still do not know
- Whether LEAP service margins reach the rest of the service business by 2028. Only management's word says so.
- What the $11.75B castings purchase earns. Management promises a return of at least 10% on it by year five.
The evidence under this - 2 claims
- None of it appears in a filing. GE publishes no margin by engine programme, no LEAP services margin and no GE9X loss figure, so there is nothing to check the 2028 turn against and nothing to notice if it slips.
- 2028 is two years beyond the guidance horizon. The same management declined to raise guidance in April 2026 on a strong first quarter, citing uncertainty it could not see through one quarter ahead.
- The chief financial officer also said the external channel will take about 30% of LEAP services by 2030. A third of the work moving to third-party shops is a margin mix change running the other way, and GE publishes no attach rate that would let a reader weigh the two.
- The company has said LEAP services broke even only in 2024, so the starting point of the recovery is recent and the slope is entirely asserted.
- The $2.0B revenue, the $200M of synergies and the year-five return are GE's own projections in its own deal deck. Nothing about them is filed or audited, and no pro forma financial statement for the target exists yet.
- The accretion claim is stated after excluding one-time costs and deal-related amortisation, which is to say it is accretion to a measure that removes most of what an acquisition costs.
- 26 times profit before synergies is close to GE's own enterprise value of 28.4 times trailing profit before depreciation, so GE is paying roughly its own multiple for a foundry - and the shares fell 2.8% the session after the announcement.
- It does not close for a year. Every number in it is a 2027 estimate made in 2026, and GE has no post-separation record of integrating a purchase this size.
What would change our view
- Neutral→AttractiveServices convert at a price that is not thirty years out
It needs all of:
- ○Commercial service sales keep growing above 10%, LEAP service margins catch up by the end of 2028, and GE9X losses peak in 2028.checked at the next results, due in Jan 2027
- ○The shares cost about 22 times the free cash guided for 2026, a 4.5% yield.about $192.74 today, 41% below the last close
- Neutral→UnattractiveSomeone else supplies the parts
It needs any of:
- ○Approved outside parts or independent shops take a visible share of overhauls on GE engines.watched as it happens
- ○The old insurance business needs fresh capital from the aerospace business.watched as it happens
We would also be wrong if
- Commercial service growth falls below 10% for two quarters running with no supply explanation.

Our external channel has gone from sub 10% of our overall LEAP services portfolio to call it mid-teens right now, and we expect that to grow to, say, 30% by the time we get to 2030. || When you look at the CFM56, even obviously the legacy narrow body platform, it's still a relatively young fleet, and we'd argue with a lot of life left in it. There are fewer long-term service agreements on those engines than we would see in the wide body segment. 30% of that fleet hasn't seen the first shop visit. 2/3 haven't even seen the second shop visit. || you look at the GE90, for example, 70% of that installed base has yet to see shop visit two, which has a significant step up in work scope. || Overall, the CFM56 work scopes should remain stable from now till 2028, 2029, because there's hardly any used material in the market, the retirements are low. || First-half departures were roughly flat, but we have not observed any changes in customer behavior. We expect a gradual return to modest departures growth in the second half.
