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.
Airbus books 142 firm orders as Boeing retracts from the Paris Air Show
By Bjorn Fehrm
June 19, 2025, © Leeham News at Paris Air Show: Boeing chose to scale down its participation at this week’s Paris Air Show out of respect for the victims of the Air India crash last week. This left Airbus and Embraer to announce new orders, with a total of 142 firm orders for Airbus and 60 for Embraer.
Outside the order activity for the three large airliner OEMs, it was a relatively quiet show, with few noteworthy announcements of advancements in areas such as Sustainable Aviation.

Airbus sees Boeing as medium-term competitor, with Comac next
By Scott Hamilton
June 14, 2025, © Leeham News: Airbus and Boeing forecast a significant production gap during the next 20 years of more than 2,000 aircraft per year in their current outlooks released in conjunction with the Paris Air Show. The event begins Monday.
Neither company can fill this gap given their current production rates and the goals they have for the rest of this decade.
This means other manufacturers must step up. The question is who?
China’s Comac is current producing a competitor to the Airbus A320neo and Boeing 737 MAX, the C919. But the production rate is excruciatingly low.
Comac also has plans for a widebody airplane to compete with the Airbus A330-900 and Boeing 787. If past is prologue, development of this aircraft will be much longer than the target entry into service of 2029.
Embraer currently is the world’s third largest airliner manufacturer. However, its jets seat between 76- and 144 seat. The company is studying whether to enter the mainline jet sector, but the decision seems a year or more away.
Start-up JetZero wants to develop a Blended Wing Body aircraft for the 250-300 seat sector. But it has little money, no engine and, LNA believes, little hope of meeting the ambitious timeline of having a demonstrator aircraft by 2027.
In a media briefing on June 13, Airbus named Boeing as its medium-term competitor; China is most like to become one; Embraer is a question mark; and JetZero appears to be making little progress, in its view.
Airbus Canada CEO: Airbus is here to stay in Canada

June 14, 2025, © Leeham News: Airbus Canada President and CEO Benoit Schultz is quietly confident that the A220 program has turned the corner and put the worst of its recent problems in it rear-view mirror.
Hosting the official opening of the Mirabel Delivery Centre (CDL), where airline representatives arrive to inspect and formally accept possession of their aircraft, he was definitive in how committed the company is to the program. “I want to say Airbus is in Canada, in Quebec, to stay. We’ve made that investment in the program now seven years ago with the view of the long-term partnership and with the view of the value that we can bring to our customers building our aircraft here in Canada.”

In addition to the pandemic and tariff hurdles that all OEMs have had to grapple with, the A220 was hit with engine snags, due to a problem with the Pratt & Whitney geared-turbofan (GTF) powered-metal coating.
This limited the time-on-wing (ToW) interval, which is getting resolved. Current engine deliveries, fresh from the factory, are approaching 10,000 hours before heavy maintenance checks, according to Schultz – with further improvements forthcoming.
Airbus forecasts that almost three times more aircraft needs to be produced by year 2044

Thursday, 12, 2025, © Leeham News: Airbus has released its forecast for new airliners needed between 2024 and 2044. The forecast says there is a need for 43,420 new aircraft over the next 20 years. It means we need to produce and deliver an average of 2,170 aircraft per year during the period.
During 2024, the world deliveries were 1,200 airliners. To meet the Airbus-predicted demand, production and deliveries of aircraft by 2044 must almost triple.
We examine what this means for the existing OEM structure and the opportunities it presents for new players in the commercial aircraft industry.

Summary:
- The growth in air travel and, consequently, the demand for new aircraft is expected to continue unabated over the next 20 years.
- With 1,200 aircraft delivered in 2024 and the need for more than 3,000 aircraft by 2044, there are opportunities for new players to enter the market.
Boeing’s 737 North Line and the Everett factory: in transition now
Open to all Readers

June 9, 2025, © Leeham News: Boeing announced the addition of a fourth 737 production line in 2023 as the last 747 rolled out of the Everett (WA) widebody factory where the Queen of the Skies was born.
To meet burgeoning demand, Boeing said it would assemble the 737 in Everett. Plans were put on hold a year later when the Alaska Airlines flight 1262 experienced a full cabin depressurization on a new 737-9 MAX minutes after take off from Portland (OR). A failure by Boeing during the assembly to resecure a door plug led to a 60-lb piece blowing out of the fuselage.
The Federal Aviation Administration (FAA) froze Boeing’s plans for the Everett 737 production on what’s called the North Line.
Boeing’s CEO Kelly Ortberg reaffirmed plans to establish the North Line. Doing so requires FAA approval. The North Line will be exclusively for the 737-10 MAX, which has yet to be certified by the FAA.
Boeing has quietly been laying the groundwork for the new line in the intervening year. Tooling, floor plans and other elements necessary to establish the line continued at a low pace. The company recently leased about 250,000 of space in a nearby industrial park to serve as a staging area for 737 kits.
The North Line will supplement the main 737 factor in Renton (WA), which is slowly returning to higher rates from a complete production suspension in 2019 following the grounding of the 737 after two fatal accidents of the MAX five months apart. The root cause of both accidents was a design flaw in the flight control system.
Boeing quietly returned to a 737 production rate of 38 a month on May 30, keeping a low profile in deference to the FAA, reported The Air Current on June 2.
Does an A220-500 need a new wing and engines? Part 3.

By Bjorn Fehrm
May 29, 2025, © Leeham News: We are writing an article series about stretching the A220 to a capacity in the A320neo range. The idea is to replace the A320neo over time to make room in the A320/321 production lines for more A321s and extend the A220 family with a larger variant.
We analyzed what we need to change to bring the capacity to the level of the A320neo. We could achieve this with a fuselage stretch, but then the Maximum TakeOff Weight (MTOW) would need to increase to keep the A220 range. The wing and engines would then have problems, the takeoff run would get longer, and the climb to an efficient initial cruise altitude would be affected.
We now examine the potential fixes for these problems.

Summary:
- The A220-300 wing is not highly loaded compared to other Airbus single-aisle aircraft. With some modifications, it should be sufficient for an A220-500.
- The A220 engine is the mid-sized Pratt & Whitney geared turbofan, the PW1500G. It has limited thrust stretch capability. An alternative for a long-range (and thus heavier) A220-500 would be the CFM LEAP-1B from the 737 MAX.
Services are driving revenues and profits in difficult times, Part I

May 15, 2025, © Leeham News: The aerospace industry is a maintenance-intensive operation, where strict regulatory rules drive many requirements.
Assets must be constantly maintained, governed by the time or usage an airline derives from them.
This goes for airframes, engines, and human resources.
Services account for a large part of aerospace corporate profits. Boeing’s Global Services division is the most profitable part of the company. Photo credit: Boeing Global Services.
Some equipment manufacturers derive little or no profits from product sales, but they make lucrative and long-term revenues from attached maintenance contracts.
Political factors are also coming into play in the services segment.
As airlines are forced into a difficult and expensive decision regarding the payment of tariffs on new aircraft they acquire, many could opt for a different strategy.
Older aircraft that were due for replacement with newer, more fuel-efficient jets will be sent into MRO facilities for an additional heavy-maintenance check.
With falling fuel prices playing less of a factor in the acquisition decision, airlines will be tempted to defer deliveries (thus avoiding the payment of tariffs) using their current assets in their installed fleets.
Extending an aircraft’s useful life by another six to seven years will allow carriers to simply wait out the tariff threat when things return to normal.
LNA looks into the growing services revenue segment among various companies in the aviation industry.

May 5, 2025, © Leeham News: We started the articles series about stretching the A220 to a capacity in the A320neo range last week by going through the development of the A220-100 and -300, how it’s designed and compares to the competition in the 100 to 140 seat segment.
Now, we analyze what we need to change to bring the capacity to the level of the A320neo and whether changes to the wing and engines, in addition to prolonging the fuselage, are necessary when we increase its capacity.
We use the Leeham Aircraft Performance and Cost Model (APCM) to look at the design data for the A220-300 and discuss what it will mean to make the different changes.

Summary:
- The A220-300 has field and range performance that matches an A320neo.
- As we increase the length of the A220 fuselage to match the seating capacity of the A320neo, we run into tricky trade situations regarding range and field performance for an A220-500.
Airbus 1Q2025 results: So far, so good, but US tariffs make future results unpredictable
May 1, 2025, © Leeham News in Toulouse: Airbus CEO Guillame Faury and CFO Thomas Toepfer presented the Airbus 1Q2025 results yesterday. All Airbus divisions performed to plan, producing a group EBIT Adjusted of 0.6bn Euro.
The company delivered 136 aircraft, which was to plan. The lower deliveries than last year (142) were due to CFM’s extra delivery efforts in 4Q2024, leading to fewer LEAP deliveries for 1Q2025. EBIT at €0.5bn and Free Cash Flow at -€0.3bn were also as planned.
The big unknown going forward is the effect of the US tariffs and the trade war it has caused. Airbus CEO, Guillaume Faury, said, “Airbus will not cover tariffs applied to Airbus aircraft that are imported to the US for US customers (read A330 and A350). For A220s and A320s produced in Mobile for US customers, tariffs apply for parts that must be imported to produce these aircraft. The effects are here less clear as the tariff situation can change at any time”.
