Zhang Wei sits in his Beijing office, staring at the latest production reports from Comac’s Shanghai factory. As a senior buyer for China Eastern Airlines, he had high hopes when his company became the first to order the domestically-built C919 passenger jet. Three years later, those dreams of a Chinese aviation revolution feel more like a slow-motion disappointment.
“We expected to have dozens of these planes by now,” Zhang admits quietly to a colleague. “Instead, we’re still waiting for our third delivery.”
Zhang’s frustration mirrors a broader reality that’s shaking China’s aviation ambitions. The Comac C919, once hailed as the aircraft that would finally challenge Boeing and Airbus, is stumbling badly in its race to reach the skies.
When Big Dreams Meet Factory Floor Reality
The Comac C919 was supposed to be China’s ticket to the big leagues of commercial aviation. Designed to compete directly with the Airbus A320neo and Boeing 737 MAX, this narrow-body aircraft represented more than just another plane – it symbolized China’s technological rise and independence from Western manufacturers.
The numbers tell a harsh story of missed expectations. By December 2025, Comac had delivered only 13 C919 aircraft to customers, exactly matching their 2024 performance. That’s roughly one plane per month, a pace that would make even the most patient airline executive wince.
“The production rate is simply not keeping up with industry standards,” explains aviation analyst Maria Santos. “Boeing and Airbus deliver hundreds of similar aircraft each year. Comac is struggling to reach double digits.”
The original 2025 target was ambitious but achievable: 75 C919 deliveries. When supply chain pressures mounted across the aviation industry, Comac quietly revised that number down to 25 aircraft. Even that reduced goal now looks optimistic, with the company likely to miss it by roughly half.
Breaking Down the C919’s Struggles
Several factors are conspiring to keep the Comac C919 grounded longer than expected. Understanding these challenges helps explain why China’s aviation dreams are taking longer to materialize:
| Challenge | Impact | Timeline |
|---|---|---|
| Supply Chain Issues | Critical component delays | Ongoing since 2023 |
| Certification Hurdles | Limited international approval | Expected through 2026 |
| Production Scaling | Factory output remains flat | No improvement in 2 years |
| Quality Control | Extended testing periods | Adding months to delivery |
The supply chain problems hit particularly hard. Unlike Boeing and Airbus, which have decades of established supplier relationships, Comac relies heavily on international partners for crucial components. When global supply chains tightened, the C919 program felt the squeeze immediately.
- Engine systems sourced from CFM International face delivery delays
- Avionics packages require complex integration testing
- Landing gear and hydraulic systems need extensive quality checks
- Interior components face shipping bottlenecks from European suppliers
“Building aircraft isn’t just about assembling parts,” notes former Boeing engineer James Mitchell. “It’s about managing thousands of suppliers, coordinating complex logistics, and maintaining quality standards that airlines trust with passengers’ lives.”
What This Means for Airlines and Passengers
The C919’s production delays are rippling through China’s aviation sector in unexpected ways. Airlines that bet early on the domestic aircraft now face difficult decisions about their fleet planning.
China Eastern Airlines, the C919’s launch customer, had hoped to operate at least 20 of these aircraft by now. Instead, they’re still learning to maintain and operate their first few planes while waiting for additional deliveries that keep getting pushed back.
“We’re committed to the C919 program, but we also have passengers to serve,” explains a senior China Eastern executive who requested anonymity. “When domestic aircraft don’t arrive on schedule, we still need to buy from Boeing or Airbus.”
For passengers, the delays mean fewer options and potentially higher ticket prices. China’s domestic air travel market continues growing rapidly, but without sufficient C919 production, airlines must compete for limited slots from established manufacturers.
The international implications run even deeper. Airlines outside China watch the C919’s progress closely, hoping for a third major manufacturer to break the Boeing-Airbus duopoly. These delays push that possibility further into the future.
Can Comac Turn Things Around?
Despite current struggles, industry experts haven’t written off the C919 completely. The aircraft itself receives generally positive reviews from pilots and maintenance crews. The underlying technology works – the problem lies in scaling up production efficiently.
“Comac is learning lessons that Boeing and Airbus figured out decades ago,” observes aviation consultant Sarah Chen. “The question isn’t whether they can build good aircraft, but whether they can build them fast enough to matter in today’s market.”
The company faces a critical window in 2026 and 2027. If production rates don’t improve significantly, airlines may lose patience and redirect orders to more reliable suppliers. Some industry watchers suggest Comac needs to reach at least 50 annual deliveries to maintain credibility with major customers.
Meanwhile, Boeing and Airbus aren’t standing still. Both companies continue ramping up their own production lines, making it even harder for the C919 to gain meaningful market share.
The Bigger Picture for Chinese Aviation
The C919’s struggles reflect broader challenges facing China’s push for technological independence. Building world-class commercial aircraft requires not just engineering expertise, but also sophisticated manufacturing systems, global supply chain management, and international certification processes.
“Success in aviation takes time, sometimes decades,” reminds former Airbus executive Philippe Dubois. “The real test isn’t whether Comac stumbles early – it’s whether they learn from these setbacks and build sustainable production capabilities.”
For now, Zhang Wei and millions of other aviation professionals continue waiting. The C919 represents more than just another aircraft option – it’s a symbol of whether emerging economies can challenge established Western dominance in high-tech manufacturing.
The answer to that question remains literally up in the air, waiting for Comac to prove it can deliver on its promises at the scale and pace the modern aviation industry demands.
FAQs
What is the Comac C919 and why is it important?
The C919 is China’s first domestically-produced large passenger aircraft, designed to compete with Boeing 737 and Airbus A320 planes in the global market.
How many C919 aircraft has Comac delivered so far?
As of December 2025, Comac has delivered only 13 C919 aircraft to customers, far below their original targets.
What’s causing the production delays?
Supply chain issues, certification hurdles, quality control requirements, and challenges scaling up manufacturing are the main factors slowing C919 production.
Are there any airlines currently flying the C919?
Yes, China Eastern Airlines is the primary operator of C919 aircraft, though they have far fewer planes than originally planned.
Could the C919 still succeed despite these setbacks?
Industry experts believe it’s possible, but Comac needs to significantly improve production rates and resolve supply chain issues to remain competitive.
When might we see more C919s in the sky?
If Comac can address current production challenges, meaningful increases in delivery rates might not occur until 2027 or later.
