The COMAC Question: China Took Cars. Does It Take Commercial Aviation Too?

China's carmakers went from also-rans to the world's biggest exporters in roughly half a decade, and the reflex is to assume aircraft are next. The honest answers are messier: partly inevitable, later than Beijing hopes — and the West's best move is not the one it keeps reaching for.

In 2025, BYD sold about 2.26 million battery-electric cars — more than Tesla, which managed 1.64 million and shrank doing it. Chinese manufacturers shipped over a million BYDs alone to foreign markets, and China as a whole has been the world's largest car exporter since it passed Japan in 2023. A decade ago the serious people in Stuttgart and Detroit called Chinese cars derivative, unsafe, and unsellable abroad. The serious people were wrong, and the industry they ran is now fighting a rearguard action behind tariff walls.

So when COMAC's C919 taxis past an A320neo at Hongqiao, it is fair to ask whether commercial aviation is watching its own future in someone else's rear-view mirror. Fair — but not simple. Aviation is not the car business with wings, and the differences are precisely where the answer lives. This piece takes the three questions readers keep asking us and tries to answer them without cheerleading in either direction: Is China's rise to the top of commercial aviation inevitable? If it happens, when? And if it happens, what can the West actually do about it — and will any of it work?

First, the scoreboard — without the drama

Start with what is countable. Through the end of 2025, COMAC had delivered 32 C919s, all to Chinese customers. It delivered roughly 15 in 2025 against a target it set much higher, and shipped just three in the first quarter of 2026 — a pace its own airlines' fleet plans say should more than double, with Air China, China Eastern and China Southern expecting 33 of the type this year. The order book stands somewhere north of 700 aircraft, though nearly 500 of those sit with undisclosed customers, which in China usually means state-adjacent buyers whose firmness is a matter of policy rather than contract.

Against that: Airbus delivered 793 commercial aircraft in 2025 and Boeing about 600, per the official figures in our own delivery dataset. Run the arithmetic and it lands somewhere between sobering and comic — Airbus alone handed over more jets in an average week of 2025 than the C919 program managed in the entire year. The duopoly's combined backlog is around 16,000 aircraft, a queue we've written about at length. COMAC today is not a competitor to Airbus and Boeing. It is a rounding error with a flag.

But the C919 is the wrong place to look if you want to see the playbook. Look instead at the smaller C909 regional jet: more than 210 delivered by March 2026, roughly 70% of China's regional fleet, and — this is the part that matters — flying revenue service outside China with TransNusa in Indonesia, Lao Airlines, and VietJet in Vietnam, which leased ten more this spring for cross-border routes. Cambodia has signed for the type. The aircraft comes bundled with Chinese financing, Chinese crews and wet-lease support, and patient state credit. That is not how Toulouse sells airplanes. It is exactly how Chinese firms sold their first million cars abroad: start where the incumbents aren't looking, subsidize the early adopters, and let the product improve in service.

Question one: is it inevitable?

Split the question in two, because it hides two different claims.

At home, yes — barring self-sabotage. China will be around 20% of world aircraft demand for the next two decades; Boeing's own market outlook puts the country's needs at roughly 8,560 new airplanes through 2043. Beijing controls which airlines order what, and it has demonstrated for a decade — three times, with 300-aircraft state-visit orders steered to Boeing or Airbus depending on the diplomatic weather (we mapped that pattern here) — that Chinese fleet demand is an instrument of policy. Once COMAC can build enough aircraft, the demand will be allocated to it. The only question at home is production capacity, and production capacity is the one problem the Chinese system reliably solves. Even the sober middle-ground forecast — Cirium's analysts see the C919 taking around 25% of Chinese single-aisle deliveries over twenty years, against 45% for Airbus and 30% for Boeing — would make COMAC a permanent fixture in the world's largest single market. We would treat that 25% as a floor, not a ceiling.

Globally, no — and here is precisely why the car analogy breaks. A car needs no one's permission to be good. A Chinese EV that beats a Volkswagen on price and features wins the customer directly; the regulatory hurdle is crash-testing, weeks of work. An airliner is different in four structural ways:

• Certification is a border. A CAAC type certificate is valid in China and in countries that choose to accept it. To sell into most of the world's serious aviation markets, and crucially to be financeable by the global leasing industry, an aircraft needs FAA or EASA paper. That gate is controlled by the competition's home governments.
• The engine is not Chinese. Every C919 flies on the CFM LEAP-1C, built by GE and Safran, with Honeywell APUs and Collins avionics behind the panels. When Washington suspended export licences in May 2025, C919 production effectively stopped within weeks, until the ban lifted in July. There is no starker proof of dependency than a national-champion program idled by a single foreign paperwork decision.
• The product cycle is 20 years, not 3. BYD can out-iterate Tesla annually. The C919 is a 2010s design that will still be COMAC's frontline narrowbody in the 2030s, flying against an A320neo family that keeps absorbing incremental improvements and, eventually, against clean-sheet Western successors.
• Airlines don't buy airplanes; they buy decades of support. Spares in Nairobi on a Sunday, retained residual value, a lessor willing to take the asset back. This is buildable — the C909's Southeast Asian bridgehead is the pilot project — but it is built in decades, not product launches.

None of these four is a law of nature. The engine gap is being closed deliberately: the domestic CJ-1000A has completed design and is in certification testing now, with Chinese approval projected around 2027 and meaningful production near 2030 — and the current five-year plan names its acceleration a national priority. Certification travels with geopolitics: much of Asia, Africa and Latin America will accept Chinese paper long before Cologne does. So the honest answer to question one is: China becoming a major, permanent, third global manufacturer looks close to inevitable. China overtaking Airbus and Boeing globally is not inevitable — it requires the CJ-1000A to work, a competitive widebody, a genuinely new-generation narrowbody after the C919, and at least one serious Western stumble. Only the last item is outside Beijing's control, and recent history suggests one shouldn't bet too heavily against Western stumbles.

Question two: if it happens, when?

Forecasting this industry has embarrassed better analysts than us, so we will show the dated milestones and let readers stress-test them. The dates below are drawn from the programs' own current status, regulators' stated timelines, and independent forecasts — not from COMAC press releases, which have missed every production target the company has ever set.

Our answer to question two, compressed: China takes its own market in the 2030s. The 2040s is the earliest decade in which "overtaking the West" is even a coherent sentence globally — and only if a second-generation product line exists by then.

Question three: what does the West do — and does any of it work?

Five moves, roughly in order of how often they are reached for, which is close to the reverse order of how much they matter.

1. Export controls: the proven weapon that expires

The May–July 2025 licence suspension demonstrated the West's kill switch works today: no LEAP-1C, no C919. As leverage in a trade fight, it is real. As strategy, it has a countdown clock attached, because every use of it converts a Chinese cost-benefit debate about indigenization into a national-security imperative. The CJ-1000A's promotion to headline status in the current five-year plan is a direct consequence. Verdict: highly effective until roughly 2030; actively counterproductive after that, because it guarantees the dependency it exploits gets engineered away.

2. Certification as a moat

EASA's validation of the C919 — pilots have been flying evaluation sorties out of Shanghai since late 2025 — is being run seriously and slowly, with the agency itself signalling 2028 at the earliest and possibly 2031. Nobody needs to act in bad faith for this to function as industrial defense; thoroughness alone does the job. It will keep COMAC out of Western fleets and out of most leasing portfolios for years. What it cannot do is stop the C909-style expansion through Southeast Asia, Africa and Central Asia, where CAAC bilaterals and bundled financing already suffice — and those happen to be the fastest-growing aviation markets on earth. Verdict: buys a decade in markets the West already owns; buys nothing in the markets that decide the future.

3. Compete harder: rate, price, and presence

Airbus's actual China strategy is instructive: it is not fighting COMAC, it is enveloping it — a second Tianjin assembly line, over half the in-service Chinese fleet, and a 9,570-aircraft 20-year forecast for the country that it intends to keep supplying from inside. Boeing, after a six-year order drought, came home from the May 2026 state visit with a 200-jet order. The duopoly's real vulnerability is self-made: with a decade-long queue, the marginal airline that cannot get a delivery slot until 2036 is precisely the customer COMAC needs. Every A320 slot that slips is a sales lead for Shanghai. Verdict: necessary and partially working — but the backlog means the West is rationing exactly the thing whose scarcity feeds its challenger.

4. The clean-sheet jump

The move that actually settles this: ship the next generation. If Airbus and/or Boeing put a 20–25%-better narrowbody into service in the mid-to-late 2030s — open-fan or otherwise — the C919 spends its maturity competing against the past, the way Chinese airliners of the 2000s did. This is the one lever COMAC cannot counter with financing or patriotic fleet orders, because airlines buy fuel burn with a ruthlessness no diplomacy overrides. It is also the lever in the worst repair: Boeing is years from being able to bet the company on a new program, and Airbus has little commercial incentive to obsolete a machine it sells 60-plus times a month. Verdict: the only durable answer — and the one the incumbents' own incentives currently argue against. This is where the 2040s get decided.

5. Tariffs and trade walls

Whatever their politics, tariffs on Chinese aircraft would protect markets COMAC was never going to win this generation anyway. The EV precedent is exact: European tariffs slowed BYD's import growth and accelerated BYD's factory in Hungary. And the West enters any subsidy argument with unclean hands — Airbus and Boeing spent seventeen years at the WTO proving each other's state support. Verdict: politically irresistible, strategically near-irrelevant.

What we'd watch

Strip away the rhetoric on both sides and the whole question comes down to a handful of observable, dateable events. Our shortlist:

• The CJ-1000A certification date. The single most important number in this story. Before it, COMAC operates on Washington's sufferance; after it, export controls are spent ammunition.
• The first C919 delivered to a non-Chinese operator — and, separately, the first ordered by an airline no Chinese bank is financing. The second matters more.
• EASA's decision, whenever it lands. A validation in 2028–2029 changes lessor behavior overnight; a slide past 2031 tells you the moat is being maintained.
• An engine selection for the C929. Until the widebody has a powerplant, its schedule is a press release.
• A Western clean-sheet launch decision. The day Boeing or Airbus commits to a new narrowbody is the day the 2040s stop being COMAC's to lose.

The Chinese car industry's victory was not won by Chinese carmakers alone; it was co-authored by incumbents who spent the decisive decade defending the products they had instead of building the ones that came next. Aviation's incumbents have been handed something Detroit and Wolfsburg never got: a challenger moving on a twenty-year clock, and therefore time. One more product cycle's worth. What they do with it — not export licences, not certification calendars — is the actual answer to question three.
