Background to a new series
May 3, 2026, © Leeham News: Boeing has more than 30 777-9s built and stored at the Everett (WA) Paine Field, where the 777s are assembled.
Some have been stored since 2020. Years of testing, fixing, and certification delays pushed the anticipated delivery to next year. However, every stored aircraft must undergo change incorporation first to meet the standards required by the Federal Aviation Administration (FAA), which involves years of scrutiny, system updates, and fixes identified in testing.
Beginning tomorrow, LNA will publish a five-part series on incorporating change. Boeing has received a lot of publicity about this practice since the March 2019 grounding of the 737 MAX, the early 787s that were rife with design and production issues, and the suspension of 787 deliveries beginning in October 2020. These programs had unprecedented levels of change incorporation required.
However, the process isn’t new, and Boeing learned a lot over the decades. LNA describes the evolution of change incorporation since the Boeing 767 program. The 767 was originally designed as a three-crew cockpit. A few airplanes were produced in this configuration. After the FAA approved operation by two-person crews, Boeing had to change these airplanes from three- to two-person cockpits and change those in production.
LNA recounts change incorporation for the 767, 747-400, 777 Classic, 787, and the 777X.
CEO Kelly Ortberg, responding to a question on the 1Q2026 earnings call, gave a high-level outline of what Boeing faces with the 777X.
Bjorn’s Corner: Blended Wing Body Airliners. Part 8
By Bjorn Fehrm
May 1, 2026, ©. Leeham News: We are making a series of articles on the Blended Wing Body (BWB) as a potentially more efficient design for passenger-carrying airliners than the classical Tube-And-Wing (TAW) configuration.
In the seventh article last week, we discussed the structural difference between a BWB and a Tube-And-Wing aircraft. The classical aircraft has divided the cabin pressure problem, causing cyclic pressure stress on the cabin enclosure, by enclosing the cabin in an optimal closed-tube configuration, and the wings’ aerodynamic stresses from gusts, hard landings, and the possible engine-out case are managed by a one-piece wingbox from tip to tip of the wing. These loads differ in character and therefore use different structural concepts in tube and wing aircraft.
The BWB mixes these loads, where the cabin shape, being a wide and long box-like compartment, complicates the structural concepts, where fatigue-sensitive bending loads from the cabin pressure are hard to avoid. It’s not made easier by the wing loads being absorbed by the same structure.

Now we look at some BWB passenger-compartment challenges compared with TAW solutions.
MTU Aero Engines posts Q1 gains, sees continued strength despite geopolitical pressures
By Thomas Blackwood
April 30, 2026, © Leeham News: Operating profit and revenues at Germany’s MTU Aero Engines were up in the first quarter of 2026 amid a strengthening position across both the military and commercial divisions.
Adjusted revenue was up 7% from €2.1 billion to €2.2 billion, while adjusted operating profit reached €320 million, 6% higher than in the first quarter of 2025 (€300 million).
The adjusted EBIT margin held steady at 14.2%, compared with 14.3% in the prior-year period, and adjusted net income grew by 3% from €221 million to €229 million.
The company confirmed its guidance for the full year and said that despite the uncertainty with the Iran conflict the board was “confident” it would reach the targets set, of full year adjusted revenue of between €9.2 billion and €9.7 billion, and adjusted EBIT of between €1.35 billion and €1.45 billion.

April 30, 2026, © Leeham News: Venture capital is flooding into autonomous air traffic control. The investor enthusiasm is rational. The regulatory assumptions behind it are not.
The money Is pouring in for Air Traffic Control (ATC), and it has nothing to do with the Federal Aviation Administration (FAA).
Over the past 18 months, a wave of startups has emerged claiming they can automate pieces of ATC using artificial intelligence. Y Combinator backed Enhanced Radar Systems. GTMfund led Oureon Technologies’ $3.5m pre-seed. NoamAI debuted at Airspace World 2025. Venture capital firms that wouldn’t have known what a TRACON was two years ago are now writing checks to companies promising AI-powered air traffic control.
On its face, the investor thesis makes sense. Only 23 of the FAA’s 313 staffed ATC facilities are fully staffed. The controller workforce is aging, recruitment is lagging, and training pipelines are years behind demand. NextGen—the FAA’s multi-billion-dollar modernization program—is roughly 16% complete after $7.5bn invested. The drone market is projected to see 800 million additional flights over the next decade.
The eVTOL companies, Joby, Archer, BETA Technologies, and Wisk, have collectively invested billions to certify aircraft that will operate in airspace where no traffic management infrastructure currently exists.
The market drivers are real. The pain is real. The technology is advancing. So why should anyone pump the brakes?
Airbus 1Q2026 Results: First quarter “suffering”
By Karl Sinclair
April 28, 2026, © Leeham News: An abnormally downbeat Guillaume Faury, CEO of Airbus, was clearly not pleased with how things progressed in the first quarter of 2026.
When asked when commercial aircraft delivery rates will converge with production rates, he said, “We don’t like to guide or to give rates when it comes to monthly production rates or even quarterly production rates. It’s non-linear and tends to be backloaded in Q2 and Q4 in most years. That’s something that we are suffering from probably more this year than I remember we’ve ever suffered in the first quarter. But we believe, we hope, we believe we should be reasonably back to where we should have been by the end of H1.”
Faury outlined a series of issues plaguing the company, calling it a “desynchronization between production and delivery,” which includes panel quality issues, an “administrative delay” that affected the delivery of nearly 20 aircraft to China, the Pratt & Whitney engine problems, ongoing seating shortfalls, the continuing tariff war, and the recently started Iranian War. The latter two were launched by President Donald Trump.
While he was detailing the current travails of the company, Faury said, “As the basis for its 2026 guidance, the company assumes no additional disruptions to global trade or the world economy, air traffic, the supply chain, its internal operations, and ability to deliver products and services.”
The tenor of the earnings call is somewhat surprising. But Airbus underperformed in its first quarter results. However, this is hardly a “It’s time to sell the silverware” moment.
As aerospace companies pursue AI, FAA lags

April 27, 2026, © Leeham News: Antiquated air traffic control systems and staffing shortages of the Federal Aviation Administration (FAA) have been well-known for decades.
Budget and staffing cuts at the FAA by the Trump Administration through its DOGE policy exacerbated these issues. Also affected, but less well known, are staff cuts in the technical and maintenance areas, which also hurt FAA operations.
Even less well known is that certification by the FAA has been dramatically slowed. There are a number of reasons, and certification affects a variety of aircraft programs and companies. Boeing gets the most headlines for the continued delays in certifying the 737-7, 737-10, and 777-9. But this doesn’t stop with Boeing.
Freighter conversion programs by IAI Bedek, a company with a long-established history of converting Boeing products, ran about two years late in certifying its first 777-300ER passenger-to-freighter conversion. Mammoth Freighters, a start-up company created in competition with IAI for -300ER P2F conversions, received its STC in April, behind its 2025 target. Issues contributing to certification delays include licensing intellectual property, engineering delays within the company, and related challenges.
But an underlying issue affecting everyone, aside from staffing shortages and expertise, is that the FAA is stuck in the spreadsheet-and-hard-copy era. As companies advance to the use of Artificial Intelligence (AI), they are moving faster than the FAA.
As eVTOL and unmanned aircraft firms seek certification, the FAA must develop new regulations. When Boeing, Airbus, GE, and Pratt & Whitney design new airplanes and engines, they’re counting on AI to speed development and certification. But the FAA currently relies on spreadsheets to track details and progress. Furthermore, conflicting regulations create unexpected problems. Ed Bastian, the CEO of Delta Air Lines, called on the FAA to use AI to help solve ATC problems.

Bjorn’s Corner: Blended Wing Body Airliners. Part 7
By Bjorn Fehrm
April 24, 2026, ©. Leeham News: We are making a series of articles on the Blended Wing Body (BWB) as a potentially more efficient design for passenger-carrying airliners than the classical Tube-And-Wing (TAW) configuration.
In the sixth article last week, we discussed how the drag characteristics of the BWB and a high optimal cruise altitude have consequences for the choice of engines. The thrust lapse due to altitude is higher than for Tube-And-Wing aircraft that fly about 10,000ft lower. The JetZero Z4, therefore, needs engines adapted for high climbs and cruise conditions.
This requires engines with higher specific thrust, which means lower Bypass Ratios (BPRs). This runs counter to the development trend of modern engines, which reduce specific thrust in each generation to improve propulsive efficiency and thus lower fuel burn.

Now we look at the challenges in the structure domain for a BWB. At first glance, it should be a lighter structure than a Tube-And-Wing aircraft, as it does away with the fuselage and empennage. In reality, it’s more complicated than that.
Safran reports strong Q1 2026, with ‘little to no impact’ from war
By Thomas Blackwood
April 23, 2026, © Leeham News: French aerospace group Safran reported “very strong” results for the first quarter of 2026 with revenue reaching €8.6 billion, up 18.8% compared to Q1 2025.
The aftermarket continues to act as Safran’s primary growth driver, while civil engine activities provided a healthy boost with deliveries of LEAP engines – co-manufactured with GE Aerospace through the CFM International joint venture – rising by more than 60% and sales of spare parts and services rising by 29% and 43% respectively.
CEO Olivier Andriès told investors that the Paris-based engine maker was seeing solid momentum across both aerospace and defense, with “little to no impact” from the Middle East conflict.

April 23, 2026, © Leeham News: Expanding the use of Artificial Intelligence (AI) will be an important part of developing Boeing’s next new airplane, whatever it is.
During an appearance last month at the Pacific Northwest AIAA (American Institute of Aeronautics and Astronautics), Boeing’s VP of Product Development outlined how AIAA may be used in the future. Brian Yutko declined to specifically tie AI to any specific new airplane program. However, he addressed how this and other new technology applies to new aircraft development.
In addition, LNA has been independently learning from its sources how Boeing will use AI for its future airplane programs.
Yet for all the growing attention about AI in today’s world, it’s hardly new. As far back as 2017, Boeing began telling the world about its interests in AI. In June that year, Boeing announced that its Boeing HorizonX venture capital arm acquired a Texas firm, SparkCognition, a machine-learning company.
“SparkCognition has established itself as a machine learning technology leader, developing a cognitive, data-driven analytics platform for the safety, security and reliability of data technology for customers in energy, oil and gas, manufacturing, finance, aerospace, defense, telecommunications and security,” Boeing said in its press release.
A search of Boeing’s archives reveals announcement after announcement about AI investment, research and activities.
On perhaps a more mundane level, the maintenance monitoring systems on Boeing, Airbus and other airplanes have long been a money-saving part of operations. As airliners are enroute, these systems monitor the “health” of the aircraft. If something “wrong” is detected, a message can be sent to the airline’s maintenance department to be ready with a solution as soon as the aircraft arrives at its gate.
