Oct. 27, 2025, © Leeham News: Recent reports that Boeing is working on a new single-aisle aircraft to replace the 737 MAX and a New Midmarket Airplane (NMA), or a version of it, are fundamentally true but vastly overhyped. At a conference in Prague earlier this month, Boeing’s Darren Hulst put a damper on this speculation, but said only that Boeing was “not close” to launching a new airplane.

Boeing hasn’t publicly put any dates on entries into service of its new airplanes, whatever these may be. But internally, Boeing is of the belief that its 737 replacement won’t enter service before 2040.
This doesn’t mean that Boeing’s Product Development unit isn’t working on new airplanes in the background. The company must be ready to respond in case some other OEM introduces a new airplane before then.
Airbus’ CEO Guillaume Faury publicly said several times that it will introduce a replacement for the A320neo in 2038. But there are some within Airbus who dispute this, concluding that new technology needed to justify a new airplane won’t be ready until the 2040 decade.
The driving factor is, of course, new engines. But as LNA’s 13-part series about new airplane technology and 7-part series about new production technologies demonstrate, engines aren’t the only technology needed. However, without significant advances in engine technology, none of the others is sufficient to justify a new airplane.
Safran raises full-year guidance on record LEAP output and booming engine aftermarket
By Tom Batchelor. October 24, 2025, © Leeham News:
A strong civil engine aftermarket and a record number of LEAP deliveries saw Safran achieve a stronger-than-expected set of results for 3Q25 and the first nine months of the year.
Q3 2025 revenue stood at €7.85 billion ($9.13 billion), up by 18.3% compared to Q3 2024 – and an increase on the €7.59 billion-average Q3 revenue analysts had been expecting.
Revenue for the first nine months of 2025 amounted to €22.62 billion, up 14.9% year-on-year.
As a result, the French aerospace group said on Friday as the results were published that it was raising its full year guidance across all metrics.
Blade-out design for CFM’s RISE; 2nd A320 line in Mobile

Oct. 22, 2025, © Leeham News: The Open Rotor engine and its evolution, the Open Fan, promise dramatically lower fuel consumption compared with evolutions of the ducted fan engine. The Open Rotor has counter-rotating fans, while the Open Fan has a single rotating fan with stators that do not rotate behind it, which can be adjusted or pivoted for maximum efficiency.
Open Rotor testing in the 1980s proved noisy, offered slower cruising speeds than conventional jet engines, and caused vibration that transferred to the vertical tails of the Boeing 727 and McDonnell Douglas MD-80 test beds. Questions about maintenance and concerns over blade failure were paramount.
Developers of the Open Fan, GE Aerospace, and Safran, under the CFM International brand, say objections to the Open Rotor design have been overcome. The noise is lower than that of the CFM LEAP engine, according to testing. The cruising speed is now projected to be comparable to today’s Airbus A320neo and Boeing 737 MAXes. Maintenance durability, reliability, and dust ingestion testing aims to overcome entry-in-service maintenance shortcomings of the LEAP and competing Pratt & Whitney GTF engines.

However, industry and airline officials LNA talks to aren’t yet convinced that blade out concerns have been resolved.
“We’re designing for blade-outs,” GE’s Arjan Hageman, vice president for the future of flight at GE, said in an interview with LNA earlier this month.
Trump tariffs beginning to hurt US aerospace companies; EU competitors to benefit

Sept. 1, 2025, © Leeham News: New policies by President Donald Trump in the first six months of his second administration in trade, with the North Atlantic Treaty Organization (NATO) and the European Union (EU) are causing a what may become a significant shift in defense spending that will benefit European companies.
The added business could strengthen those that also participate in commercial aerospace, to the detriment of US companies, notably Airbus.
US companies that for decades were the major suppliers to allies are already beginning to see European countries redirect spending to EU firms. Following Trump’s imposition of high tariffs on certain EU countries and others on Aug. 1, US defense companies have been hurt. India canceled deliveries of Boeing 737-based P-8A Poseidons.

Airbus, Rolls-Royce, MTU, and others expect to benefit from these changes. And, as these companies see more defense work coming their way, then—at least in theory—their commercial business will benefit from stronger balance sheets, profits, cash flow, and perhaps the corporations’ technology.
In an interview at the Paris Air Show in June, the consulting firm Accenture told LNA that it is beginning to see key trends and increases in the defense sector.

“Obviously, things are changing in terms of the dynamics,” said Jeff Wheless, Growth & Strategy Research Leader at Accenture. “I think certainly from a NATO perspective, I think folks are increasing their spending.”
Mark Rutte, the NATO secretary general, said that Trump’s pressure on NATO countries to increase defense spending to 5% of their budgets paid off. For decades, NATO countries were committed to a 2% spending level, but often failed to meet this commitment.
“Europe is spending by far less money on defense acquisitions than the US,” said Airbus CEO Guillaume Faury in response to an LNA question at the Paris Air Show. “It’s a ratio of one to four or one to five. On top of that, Europe is procuring a lot from the US. I think the message is loud and clear from the U.S. that Europe should take better care of its own security.”
LEAP deliveries and spare parts demand lift Safran in H1 2025
By Tom Batchelor
Jul 31, 2025, © Leeham News: Safran has reported a robust set of half-year results for 2025, underpinned by booming aftermarket services, a ramp-up in LEAP engine deliveries, and strong growth across all business segments.
The aerospace and defence supplier posted revenues of €14.8bn ($16.9bn) for the first six months of the year, up 13.2% compared to H1 2024.
The Paris-based group’s propulsion division led the charge, with revenue up 16.9%, boosted by a 21.3% surge in aftermarket services and a 9.7% rise in original equipment (OE) sales.

June 23, 2025, © Leeham News, Paris: CFM International touts its Open Fan RISE engine as the wave of the future. (CFM is a 50-50 joint venture between GE Aerospace and Safran.)
Rival Pratt & Whitney says evolution of its Geared Turbo Fan is the best engine choice going forward.

Neither company will admit that it is also researching and developing a Plan B engine. For CFM, this is a conventional turbofan. For PW, this is a new Open Fan. But during the Paris Air Show, LNA confirmed that both have a Plan B engine in development.
PW has gone out of its way to dismiss the very idea of an Open Fan engine. Rick Deurloo, the president of Pratt & Whitney Commercial, won’t even talk about the “competitor.” Deurloo makes it clear—publicly, at least—that an evolution of PW’s Geared Turbo Fan (GTF) is the best solution for the next generation engine for the single aisle market, in its view.
Mike Winter, RTX’s Chief Engineer, dismissed the Open Fan as “sub-optimal” on a successor to the Airbus A320neo and Boeing 737 MAX families. It involves too many installation compromises on this size aircraft, he says. RTX is the parent of PW.
But, says one person with direct knowledge, PW fully understands that if CFM is successful in solving all the challenges of an Open Fan and meets the publicly stated goal of improving fuel consumption by 20% compared with today’s GTF and CFM LEAP engines, PW’s gain of an evolutionary GTF won’t be competitive.
So, says the person with direct knowledge of PW’s activities, the development of an Open Fan alternative engine is being worked on as PW’s Plan B.
Furthermore, PW’s sister company, Pratt & Whitney Canada, publicly disclosed its development of an Open Fan engine in a briefing on Tuesday this week. This engine is for a new 70-100-seat aircraft designed by the start-up company MAEVE. PW is following PWC’s development.

Feb. 24, 2025, © Leeham News: CFM International plans to deliver 2,500 LEAP engines by 2028, enough to power more than 1,000 Airbus A320neos and Boeing 737 MAXes plus spare engines in a single year.
CFM is the 50-50 joint venture between GE Aerospace and Safran. The 737 exclusively uses the LEAP. The A320neo family splits its powerplant business between CFM and Pratt & Whitney’s Geared Turbo Fan engines. Between the MAX and a portion of the A320neo engines, CFM has a solid majority of the market share for the mainline single-aisle aircraft sector.
CFM is the brand for the CFM56 and LEAP, but GE and Safran benefit from the aftermarket business. Between the two engines, the maintenance, repair, and overhaul business is big and profitable.
Larry Culp, CEO of GE Aerospace, spoke at the Barclays investors conference on Feb. 20.
“There’s no question that from an aftermarket perspective, LEAP on top of CFM56 is going to keep us very busy,” Culp said. “We haven’t been particularly good at calling the outlook here because we’ve undershot the reality with the CFM56 the last couple of years.”
Culp said that GE continues to believe that it’s got several years of growth ahead. “We probably don’t see an apex until probably the 2027, 28-ish time period, and then we’ll see a gradual fade with the CFM56.
“I think we’re still talking about 2,000 shop visits at the end of the decade. We’ll see if we’re right or wrong on that, but that’s our current view. I think our partners at Safran have in effect echoed that recently at their own earnings call.”
Safran hails ‘landmark’ 2024 with record results
By Leeham News Team
Feb. 14, 2025, © Leeham News: Safran has announced “record-breaking” financial results for 2024, with revenues, profits, and free cash flow all reaching new highs, helped by strong aftermarket activity and the return to profitability of its aircraft interiors division.
The strong performance has prompted an upward revision of its 2025 outlook, with revenue and income forecast to be higher than the figures given in December.
Reflecting on the 12-month period in a call with analysts on Friday morning, CEO Olivier Andriès described it as a “landmark year” for the company, despite “persistent supply chain difficulties as well as residual inflationary pressures”.
For the 2024 financial year, Safran reported adjusted revenue of €27.3 billion, a 17.8% increase, while recurring operating income surged by 30.1% to €4.1 billion, representing 15.1% of sales.
Free cash flow reached €3.19 billion, with shareholders set to benefit from a proposed dividend of €2.90 per share, pending approval.
Consolidated figures for the year were similarly robust, with total revenue at €27.7 billion and operating income at €4.19 billion.
Bjorn’s Corner: New engine development. Part 25. New versus old, CFM56 vs. LEAP
By Bjorn Fehrm
September 20, 2024, ©. Leeham News: We do an article series about engine development and why it has longer timelines than airframe development. It also carries larger risks of product maturity problems when it enters service than the airframe of an airliner.
In our look at examples of recent developments with problems and these put in a historical perspective, we compare the CFM56 to the LEAP, comparing their reliability and durability.

“Hyper focus on reliability and durability out of the gates”
By Scott Hamilton

Sept. 11, 2024, © Leeham News: GE Aerospace and Safran advance on the CFM RISE Open Fan engine with an overriding goal: “Our customers really want us to be hyper-focused on reliability and durability out of the gates.”
GE and Safran are developing a potentially game-changing engine and marketing it via the 50-50 joint venture, CFM International. The entry-into-service goal is 2035.
Customer demand for reliability and durability “out of the gates” is understandable. Engines produced by CFM, Pratt & Whitney and Rolls-Royce disappointed Airbus and Boeing customers operating the Airbus A320neo family, the Boeing 737 MAX and 787 and now the Airbus A350. Durability and/or technical issues plagued the CFM LEAP, Pratt & Whitney Geared Turbo Fan (GTF), Rolls-Royce Trent 1000 and now the RR Trent XWB-97. The giant GE9X engines on the Boeing 777X also suffered technical problems during the long, extended flight testing.
Operators protested as on-wing time fell short of promises. 787s, A220s, A320neos, and to a lesser extent Embraer E195-E2s were grounded as engines components failed, MRO shops backed up (displacing routine overhaul requirements on older engines) and new-production engines were diverted to replace those on grounded aircraft.
The CFM LEAP, GE and Safran promise, will provide a 20% reduction in fuel consumption and emissions. But the radical technology of an Open Fan gives airlines, lessors and even Boeing pause.
GE and Safran say they are progressing through development of the 35,000+ lb thrust engine but there is a lot of work to do to make it ready for service and give customers confidence.
