Dec. 22, 2022, © Leeham News: Last week, we wrote about Universal Hydrogen’s (UH2) plans to fly a hydrogen-fueled demonstrator aircraft in early 2023, followed by a certified conversion kit for an ATR72 airliner mid-decade.
The plans for the ATR72 hydrogen conversion are at an advanced state. As the first publication, we can describe the overall design and the technical details. The ATR72 implementation brings improvements in several areas compared with what’s been revealed before.

Summary:
- The target ATR72 conversion improves hydrogen capacity and handling compared to earlier concepts.
- The influence on the ATR seating capacity is reduced due to more efficient packaging on the aircraft.

Dec. 19, 2023, © Leeham News: Boeing suppliers are planning to increase their output to support the OEM’s plan to deliver five new-built 787s a month at some point in 2023.

It will be challenging for the top-tier suppliers to scale up operations dramatically. They’ll have to train and maintain larger teams of workers, while also ensuring that their own lower-tier suppliers have the capacity to deliver parts and components on time.
One executive warned investors this fall that the challenges in the year ahead will be greater than the ones the industry faced delivering record numbers of planes before the pandemic.
Summary:
- Howmet: ‘Back of the year, at around 5 per month’
- Suppliers want more lead time given challenges
- Whole supply chain is under stress

By Scott Hamilton and Bjorn Fehrm
Dec. 15, 2022, © Leeham News: Universal Hydrogen (UH2) is perhaps weeks away from its first flight of a demonstrator that equips a De Havilland Canada Dash 8-300 with tanks of hydrogen and a fuel cell electric propulsion unit. The project shall prove the feasibility of hydrogen-fueled airliners.
The first flight’s date hasn’t been firmly set, but officials at UH2 told LNA it should be soon. Taxi tests of the aircraft will begin in the coming weeks. The flight will occur at Moses Lake in Central Washington State.
Universal Hydrogen supplies its hydrogen to the aircraft in prefilled barrel-sized tanks, called capsules, to avoid the lengthy and costly investment in storing and filling infrastructure at airports. The proof of concept is with a Dash 8, followed by a complete hydrogen conversion kit for an ATR-72 turboprop airliner.

Summary:
- The core business of Universal Hydrogen is the prefilled hydrogen tanks that load onto the aircraft in pallets.
- Universal Hydrogen builds the complete hydrogen fuel and propulsion system to prove and bootstrap the concept of hydrogen airliners.
How much can China’s traffic growth slow? A look at Japan

Introduction
Dec. 12, 2022, © Leeham News: The Chinese commercial aviation market is now the second largest in the world after the United States. Growth has been very robust in recent decades, and all major OEMs forecast things to stay this way in the next two decades.

However, the Chinese economy’s GDP (Gross Domestic Product) growth rate slowed down significantly throughout the 2010 decade: from around 10% to 6% in 2019. Separately, China’s working-age population peaked during the same decade.
The growth in passenger traffic has historically had a strong correlation with GDP growth. Several studies have shown that passenger traffic has grown 1.5x to 2x faster than GDP. The consequences of a potential passenger traffic growth slowdown in China are, therefore, significant for commercial aircraft OEMs.
Another country in the Asia Pacific region faced a similar situation in the early 1990s: Japan. Even though there are substantial differences between the two countries, analyzing how things played out in Japan could help understand what lies ahead for Chinese passenger traffic growth.
Summary
- Demographic and economic parallels;
- Competition from high-speed rail;
- As Japan’s GDP grew, so did air and train travel;
- Explaining the 2010s Japan air traffic boom;
- Significant differences between China and Japan.

December 9, 2022, ©. Leeham News: This is a complementary article to Part 49, eVTOL production costs. It discusses the typical production costs of a certified eVTOL when produced in large quantities.
eVTOLs will be produced under aeronautical production certification conditions, using aeronautical grade material and system. Our production cost model predicts such costs, including learning curve effects for each material type.
The Economics of the 767 and A330 at Seven and Eight abreast

Introduction
Dec. 8, 2022, © Leeham News: In a previous article, we started speculating what an NMA type of aircraft would look like based on a Boeing 767 cross-section. An airliner’s cross-section decides the design of a large number of parts in an airplane.
In essence, a fuselage is a tube with a constant cross-section where the constant parts are repeated framewise to form the fuselage. It’s finished with a tapering forward cockpit and a rear tapering empennage.
We now look at what could have been a passenger version of an NMA that would have used the Boeing 767 cross-section with adaptations. To understand its economic impact, we make a comparison where we take a standard 767-300ER, then modify it to an NMA type fuselage and compare it to the competition in the size class, the A330-200 and -800.
As before, we do this by flying the world’s busiest long-haul route, London Heathrow, to New York JFK.
Summary
- An NMA based on an improved 767 fuselage cross-section would have been a very competitive airliner
- I would be the ideal replacement for the Boeing 757, 767, and 787-8.
Pontifications: A lost decade for new airplanes

Dec. 5, 2022, © Leeham News: In September 2020, LNA wrote that commercial aviation was facing a “lost decade.”
The impetus for this prediction was the COVID-19 pandemic crisis.
“Commercial aviation is facing a lost decade due to COVID,” we wrote. “Yes, most forecasts target 2024-2025 as returning to 2019 passenger traffic and aircraft production levels. However, LNA in July published its own analysis indicating full recovery may not occur until 2028.”
Nobody predicted that effective vaccines would emerge as quickly as they did. Drug makers in the US and Europe moved heaven and earth to produce vaccines to fight COVID-19. These have been, by and large, extremely effective. (I’ve had two shots and three boosters and have not caught COVID, despite being at one major conference with 13,000 people.)
China created its own vaccine, which failed to stem the tide there. President Xi quickly adopted total lockdowns at the first sign of outbreaks. Despite this, China is now setting records for new infections. Commercial aviation recovery there remains underperforming. China’s performance illustrates the underlying reasoning we had in concluding commercial aviation was facing a lost decade.
This sector still faces a lost decade, though for some fundamentally different reasons.
Green aviation pressure applied to banks, oil companies, too

Dec. 1, 2022, © Leeham News: Pressure from environmentalists is prompting the aviation industry to move toward sustainable fuels.
But the pressure is not just on aviation. It’s also on bankers who finance airplanes and aerospace companies. These firms must show their shareholders, stakeholders and special interest groups that they are taking sustainability into account as they finance their customers.
The pressure is on oil companies, though many believe Big Oil isn’t really interested in cutting back its core business in favor of alternative energy.
In an interview with LNA, Chris Raymond, the chief sustainability officer for The Boeing Co., is frank about the challenges of meeting commercial aviation’s goal of achieving net zero carbon emissions by 2050. But he’s optimistic that the industry is on the right path.
It’s a path that’s been promoted before, with little success. In the first decade of the 21st century, the industry talked big but little activity occurred. In 2011, Jim Albaugh, then the CEO of Boeing Commercial Airplanes, predicted that 10% of fuel by 2020 would be Sustainable Aviation Fuel (SAF). The reality was that SAF accounted for 0.001% of the fuel.

Today, there are demonstration flights, including passenger-carrying flights, that used 50% SAF.
Boeing faces exodus of senior engineers in tight market for talent

Nov. 28, 2022, © Leeham News: Boeing’s engineering corps could become further depleted within the next few days, as union-represented engineers and technical workers at the company’s Puget Sound plants face a Wednesday deadline on filing their retirement paperwork.
If they don’t leave now, individuals could face retirement benefit losses in the hundreds of thousands of dollars.
The potential loss of several hundred of Boeing’s most experienced engineers comes at a time when the company is scraping together engineering teams to tackle production problems in Charleston, and in the midst of an industry-wide shortage of engineering talent.
Summary
- Aggressive hiring sparks Brazilian lawsuit
- Engineers face Wednesday deadline
- All aerospace companies need engineers
- Tech industry layoffs won’t help

Introduction
Nov. 24, 2022, © Leeham News: Last week, we saw the impact of using a nine-abreast economy class seating configuration on the Airbus A330neo economic performance against the Boeing 787-9. The passenger comfort was similar to the A350 NPS in a 10-abreast cabin.

We now turn our attention to another aircraft family, the Boeing 767. Until a few weeks ago, Boeing’s product development team worked on a 767-sized airplane. The program would start with a freighter, the NMA-F, followed by the passenger variant.
However, comments from Boeing CEO Dave Calhoun at the Boeing annual investor conference indicated there are no plans to launch such a program. Funding for such a program was reduced.
Despite Boeing’s announcement, we still thought it relevant to look at the 767 cross-section with a mindset of what could have been.
Summary
- No adequate OEM offering in the upper mid-market segment;
- The 767 cabin shoulder width;
- Comparing mid-sized aircraft capacity;
- A dwindling 767 freighter conversion stock.
