China, Boeing appear near massive order: report
By Scott Hamilton
Aug. 21, 2025, © Leeham News: Boeing is nearing a massive order for up to 500 aircraft with China, Bloomberg reports. Completing the deal depends on political considerations, as so many of these do between China and the US for Boeing or Europe for Airbus airplanes.

But it’s significant that negotiations are active and appear nearing a deal if the politics can be worked out between the Chinese government and the Trump Administration. Boeing was frozen out by Beijing in 2017 when President Donald Trump, in his first term, began imposing tariffs on China in 2017.
President Biden, who took office in 2021, not only kept the Trump tariffs in place, economic and industrial sanctions were imposed when China covertly aligned itself with Russia following its 2022 invasion of Ukraine. When Trump was reelected in 2024, one of his first actions the following year was to impose more tariffs on China.
Even if the Boeing deal doesn’t successfully conclude soon, the very fact that serious negotiations and a near-deal validate LNA’s thesis since

LNA’s analysis over the years concluded that China’s home-grown COMAC C919 could not fill the gap for the domestic demand for new airliners in the coming years created with the 2019 21-month grounding of the Boeing 737 MAX. China was the first to ground the aircraft after two fatal crashes of the MAX five months apart in 2018 and 2019. It was the last to un-ground the MAX after the Federal Aviation Administration recertified the airplane in November 2021.

July 21, 2025, © Leeham News: Our series about “What’s the next new aircraft” was introduced last week, where we look at what potential new aircraft could be introduced over the following decades, and what technologies these would use.
In Part 2 of the five-part series, we introduce some basics around aircraft efficiency and examine what areas these 13 new aircraft aim to improve to enhance their efficiency.
In the following Parts, we will look into these aircraft in more detail and write about how challenging it will be to develop and mature the needed technologies.

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.

April 24, 2025, © Leeham News: We started looking at the future COMAC C929 widebody 10 days ago. The C929 development has gone through a number of challenges, the first being how to structure the cooperation between China’s COMAC and Russia’s United Aircraft, with the latest being what engines to use for the aircraft.
The first problem was solved by COMAC deciding to go it alone, whereas the last problem around engines has no definite solution yet.

Summary:
- The C929 airframe is taking form with detailed design having started, according to COMAC.
- The engine side is less settled. The likely engine is the Chinese CJ-2000, a 78,000lbf development of the CJ-1000A engine aimed at the C919.
- We apply the CJ-2000’s likely performance to the C929 airframe and use our Aircraft Performance and Cost Model (APCM) to predict the C929’s operational performance.
China bans Boeing, US parts imports in tariff war
April 15, 2025, © Leeham News: It was inevitable: China has banned its airlines from accepting deliveries of Boeing airplanes.
The move is in retaliation against President Donald Trump’s boosting tariffs on Chinese goods to 145%. Beijing placed retaliatory tariffs on US goods to 125%. During the first Trump administration, the president placed tariffs of 25% on Chinese goods imported to the US. Beijing has allowed delivery of very few Boeing jets since then.

The move once more blocks Boeing from the world’s second biggest aviation trade market. Additionally, Beijing blocked the import of US-made parts, according to Bloomberg News, which first reported the actions.
Boeing welcomes COMAC competition as Asia-Pacific demand soars

April 15, 2025, © Leeham News: Boeing sees long-term growth potential in the Asia-Pacific commercial market, but the company also acknowledges that China’s domestically produced COMAC C919 poses a credible challenge in the single-aisle segment—particularly in China and potentially in the broader region over time.
With China’s state-backed aerospace ambitions gaining momentum, the U.S. manufacturer faces a new challenge threatening to unbalance the traditional duopoly with Airbus.
According to Boeing’s 2024 Commercial Market Outlook (CMO), Southeast Asia will require more than 4,700 new aircraft over the next 20 years. About 80% of this demand will be for single-aisle aircraft—a space Boeing would ordinarily seek to dominate with its 737 MAX family.
COMAC may still have work to do to gain credibility for the C919 inside and outside China, but its short-medium-range airliner is proving popular in its domestic market (Air China, China Eastern Airlines, and China Southern Airlines are current operators). The planemaker is now seeking customers elsewhere in the region, including Indonesia, Cambodia, and Kazakhstan. How potential U.S. tariffs will alter airline customer decision-making between Boeing and its rivals remains to be seen.
Speaking to LNA as the Routes Asia forum got underway, Dave Schulte, managing director of Boeing Commercial Marketing for Northeast Asia, Southeast Asia, and Oceania, said he welcomed the contest for supremacy.
“Competition is always good for the aviation industry,” Schulte said when asked about the impact of COMAC on Boeing’s plans in the region. “It makes everyone in the industry invest in better technologies and find solutions to meet evolving customer needs.
“In the future, airlines will need to make longer-term fleet decisions that support growth and profitability, while providing competitive fares and service levels to the public.
“To achieve this goal, airlines across the region and globally evaluate airplanes based on performance capabilities, comfort level for passengers, economics, and more.” Read more

April 14, 2025, © Leeham News: The COMAC C919 is finding its first customers outside China. At the same time as COMAC has started work on shorter and longer versions of the C919, work on a widebody C929 has been going on for the last 14 years.
If the development of more family members for the single aisle C919 is straightforward, the widebody C929 development has presented several challenges.

Summary:
- The C929 has been in development since 2011.
- The project was first delayed by Russia-China relations and recently by increasing tensions between China and the West.
- The latest problems are around the engines, as Western engines have become politically impossible.

April 3, 2025, © Leeham News: The COMAC C919 is finding its first customers outside China, which gives us a reason to examine the aircraft.
Last week, we estimated its efficiency versus its Western “look-a-like,” the Airbus A320neo. Now, we look at new variants that have been announced and how competitive these would be.

Summary:
- The C919, sized like an A320neo, is the first variant in a family of aircraft.
- The next C919 variant is a shorter model for hot and high airfield operation.
- The following variant is an A321neo-sized aircraft.

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.
