Parent agency, FAA often at odds as politics outweighs safety
By Colleen Mondor
June 26, 2025, © Leeham News: On March 12, 2019, then-Secretary of Transportation Elaine Chao and her staff flew from Texas to Washington (DC) on a Southwest Airlines 737 MAX. It was two days after the crash of Ethiopian Airlines flight 302, the second devastating accident involving the 737 MAX.
In taking the flight, Chao showed not only her support for Boeing and Southwest, but even more so the Federal Aviation Administration (FAA), which steadfastly refused to ground the aircraft. As the pressure mounted, the agency stressed the importance of its methodical data-gathering process, which had begun months earlier with the October crash of Lion Air.
Chao also reassured the public, telling reporters “I want people to be assured that we take these accidents very seriously. We are reviewing them very carefully.” The day after her flight, President Trump announced that after conversations with Chao, the CEO of Boeing and Dan Elwell, the FAA’s acting administrator, his administration was grounding the aircraft. Elwell told reporters later that day, however, that the decision rested with the FAA. “So the decision is an emergency order to ground the airplanes,” he said, “and that is authority rested in the FAA with me.”
Chao’s flight centered her in yet another chapter of the ongoing saga between the Department of Transportation (DOT) and FAA. This was familiar territory for DOT which, since the FAA lost its independence in 1967, has often portrayed itself as the crucial, agent of flight safety in the U.S.
The most recent example was when current transportation secretary Sean Duffy captured media attention after the January 29 midair collision over Reagan National Airport. The FAA, which again had an acting Administrator, was relegated to secondary sound bites as Duffy declared, “We are going to take responsibility at the Department of Transportation and the FAA to make sure we have the reforms…to make sure that these mistakes do not happen again and again.”

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 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.

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.

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.

June 11, 2025, © Leeham News: Three manufacturers are designing engines that could be used on the replacement aircraft for the Airbus A320neo and Boeng 737 MAX families.

GE Aerospace and Safran, via their joint venture CFM International, are designing the RISE Open Fan engine. As the name suggests, the fan on open to the air and not surrounded by a nacelle. The Open Fan is an off-shoot of the 1980s Open Rotor engine that was equipped with counter-rotating fans with no nacelle. The Open Fan has only one fan, with vanes aft of it that may be adjusted to tweak efficiency.
Pratt & Whitney is placing its bet on an evolution of the Geared Turbo Fan (GTF).
Rolls-Royce is developing a new turbofan engine called the UltraFan, a conventional nacelle-equipped GTF of its own.
PW and RR believe conventional engines are the best choice for the next single aisle airplane. GE believes the RISE is the best choice.
At a media briefing in advance of the Paris Air Show, PW president of Commercial Engines Rick Deurloo basically threw down the gauntlet to GE.

June 5, 2025, © Leeham News: Decades of research and development by GE Aerospace are a key element in the potential program of a step-change engine for the next new single-aisle airliner.

The RISE open fan engine, a joint project of GE and France’s Safran under the banner CFM International, has a huge fan without an engine nacelle, hence the name “open fan.”
One major concern about an engine without a shroud or nacelle to contain a blade failure is that the engine “throwing” a blade could penetrate the fuselage, causing injury or death to the passenger and substantial damage to the aircraft.
In a briefing last week by GE Aerospace, Mohamed Ali, the Senior Vice President, chief technology and operations officer, said the RISE’s composite blades benefit from millions of flight hours of composite blades on the GE90 (Boeing 777), CFM LEAP (Boeing 737 MAX and Airbus A320neo), GEnx (Boeing 787) and GE9X (Boeing 777X) engines. None of these engines (which have nacelles) has ever thrown a composite blade.
GE says the RISE can reduce fuel consumption, and with it lower emissions, by at least 20%. RISE is currently a development program. However, the company clearly is betting that this is the wave of the future. Rivals Pratt & Whitney and Rolls-Royce instead are betting on evolutions of conventional turbofan engines as a “safer” bet.
GE targets RISE’s entry into service in 2035. Officials say the R&D remains on track to meet this date.
Engine makers emphasizing durability, reliability

June 3, 2025, © Leeham News: Engine reliability and durability for the next new commercial aviation engine for the next new single-aisle airplane has emerged as the top demand of airlines and lessors.
Burned, frustrated, and angry by shortcomings in these areas in engines from every manufacturer, potential customers prioritize getting these areas right over reduced fuel consumption and lower emissions.
Airlines have had issues of varying severity with GE Aerospace’s GEnx (the Boeing 787); the CFM LEAP (Airbus A320neo and Boeing 737 MAX); Pratt & Whitney’s Geared Turbo Fan (Airbus A220 and A320neo and Embraer E2); and Rolls-Royce (Boeing 787, Airbus A350-1000). (GE is a 50% joint venture partner in CFM, with France’s Safran holding the other 50%.)
Tim Clark, the president of Emirates Airline, has been publicly vocal about his concerns regarding these issues with the forthcoming Boeing 777-9 and its massive GE9X engine, which is now undergoing flight testing. He’s also cited durability issues with the RR Trent XWB-97 engine on the Airbus A350-1000 as his key reason for holding off on ordering this model. Emirates has just taken delivery of the first A350-900s, the smaller version of the A350, powered by the Trent XWB-84. Reliability and durability issues have been reported for the smaller -900 and lower-thrust XWB-84 in the harsh Middle East environment.
In an appearance at an investors’ conference on May 28 hosted by Bernstein Research, GE CEO Larry Culp discussed these issues with the LEAP engine and how lessons learned apply to the RISE open fan.
Digital twin is a key to JetZero’s hopes for Blended Wing Body entry

By Scott Hamilton
June 2, 2025, © Leeham News: Little in the way of product development or new airplanes is expected at the Paris Air Show, which begins on June 16. No new commercial airplane programs will be forthcoming from Airbus, Boeing, or Embraer. Nor will any new commercial engines be forthcoming from GE Aerospace, Pratt & Whitney, Rolls-Royce, or CFM International (a GE-Safran joint venture).
Instead, the air show briefings are most likely to be progress reports, discussions about new materials and sustainability.
One new entrant that is still in the research and development stage, with the production of a demonstrator aircraft underway, is JetZero. The start-up is developing a 250-passenger Blended Wing Body airplane (BWB) designed for the middle of the market (250-300 seats) currently occupied by the aging Airbus A330-200/300 and Boeing 767-300ER; and the newer Boeing 787-8 and Airbus A330neo.
JetZero has daunting tasks ahead to successfully bring its BWB, called the Z4, to the market. It needs $7bn to $10bn (it has, publicly, less than $300m). JetZero plans to make a site selection announcement any day now, before the air show. An entirely new production plant is required. It needs to build the plant, production tooling and the final assembly line.
One of the keys to the program is the reliance on a digital twin production plant and innards. JetZero has hired the giant firm Siemens to help design the digital twin, an effort that Siemens officials predict will reduce the time to build the facility by 20%-30 %.
Boeing and Airbus have identified advanced production processes as key to the next new airplane, whatever it may be. When Boeing was pondering the New Midmarket Airplane (NMA) for the Middle of the Market (MOM), officials said production was more important than the airplane itself.
Does an A220-500 need a new wing and engines? Part 3.

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.
