March 27, 2025, © Leeham News: The COMAC C919 is finding its first customers outside China, which gives us reason to examine it and estimate how efficient it would be operating a typical mission compared to its Western competitors.
We will compare the C919ER version with a 3,000nm maximum range to “its look-a-like”, the A320neo, which served as the C919 design template.

Summary:
- The C919 consumes more fuel as the airframe is larger for the same seating capacity as the A320neo.
- Due to a lack of airframe maturity, the maintenance costs will also be higher.
- The big unknown will be the capital costs as the pricing or leasing strategy of a state-owned COMAC is hard to predict.

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.”
Airbus 2024 results: “A decent year in a challenging environment”.
By Bjorn Fehrm
February 20, 2025, © Leeham News in Toulouse: The headline uses the words of Airbus CEO Guillame Faury when he opened the presentation of Airbus 2024 results in Toulouse today. It was a session where Faury and the CFO Thomas Toepfer put in an effort to let all present international journalists and their online colleagues ask all questions and deliver honest answers.
On the business-as-usual side, the company delivered 766 aircraft, which was within the guidance, after a deep grab effort in 4Q, leading to low deliveries for 1Q2025. EBIT at €5.4bn and Free Cash Flow at €4.5bn were also within guidance.
In general, the Commercial airplane side was fighting specific supply problems during 2024, which might limit the ramp-up of A350s and A220s going forward, more of which below. Helicopters have now recovered from challenging times and delivered a solid result. Defense and Space are strong in Air Power (fighters, etc.), given the tense European situation, with Space going through restructuring, which might include mergers with other European space players.
The real news was the reasons for pausing the CityAirbus eVTOL program, according to Faury, “not only because batteries were not where they should have been but also due to the lack of a market for this type of transportation.” As the world’s largest supplier of helicopters, Airbus is a credible source for such a lack of market statement.
Faury also detailed what is happening on the Hydrogen side. Due to slower-than-expected progress in Green Hydrogen production build-up, deployment of preparatory Ground Support Equipment (GSE), and Transportation using hydrogen at the airports in their H2 partner network, Airbus has decided to push out the entry into service of a “commercially viable hydrogen aircraft” by five to ten years.
However, said Faury, it has made progress. “We have reached TRL 3 for the tecnobricks, which has enabled us to select the Fuel Cell path as the preferred way forward. This means these activities are continued at the present level or even intensified, but it also means other paths (read Hydrogen burn) are ramped down. Overall, it means a decrease in R&D spending for Hydrogen activities in the coming years.”

Dec. 16, 2024, © Leeham News: A new airplane from Airbus or Boeing is years away.
Engines drive whether a new airplane program makes sense. Technology just isn’t “there” yet. In any event, Boeing can’t afford to fund a new airplane program even if it wants to. Furthermore, until its stored inventory of 737s and 787s are cleared, or mostly so, production rates are back to 2018 levels, debt is substantially reduced, and profits and cash flows return, Boeing is mired in recovery from the past. Addressing the future must wait.
Airbus has no incentive to rush into a new airplane program, even if engine technology was available. Its backlogs extend into the 2030s, and it can’t meet the current demand. Production is mired in delays for the A320 and A350 families.
Both companies, and Embraer, remain adversely affected by supply chain parts delays.
Airbus CEO Guillaume Faury previously said he doesn’t see the company moving forward with a new airplane until 2035-2040. Additional insight into the company’s thinking came last month at the Aviation Forum 2024 in Munich, where vice presidents of Airbus’ propulsion and new programs departments outlined what’s ahead.
CFM gets FAA and EASA certification for a more robust LEAP-1A turbine.
By Bjorn Fehrm
December 10, 2024, © Leeham News: CFM has announced that FAA and EASA have certified an upgrade to the LEAP-1A turbine, allowing the engine to stay on wing longer, especially in hot and harsh environments.
The upgrade was developed using a new dust ingestion method CFM developed to simulate the wear on the LEAP first turbine stage and nozzle in certain dusty environments.

Bjorn’s Corner: New engine development. Part 28. Wrapup.
By Bjorn Fehrm
October 11, 2024, ©. Leeham News: We have done an article series on why engine development takes longer than airframe development. Part of the reason is that advancements in engine technology can deliver considerably higher fuel consumption reductions than airframe advancements.
The change of engines for the A320 series and 737 MAX delivered a 15% improvement in engine efficiency. In contrast, the airframe improvement was less than half, mainly by stacking cabin seats closer together.

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

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.

August 30, 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.
We reached the turbine part on our way through the engine, where we last looked at high-pressure turbine temperatures. It’s the most stressed part of the engine and, in most cases, decides its durability. To understand why, we look closer at turbine technologies.
