China and Europe Intensify COMAC C919 Tests in Shanghai

China’s domestically built COMAC C919 has entered a more intensive phase of testing with European regulators, as the European Union Aviation Safety Agency deepens on-the-ground evaluations in Shanghai in a bid to eventually clear the jet for operation in European skies.

EASA Deepens Its Presence in Shanghai

Recent reporting from industry outlets indicates that the European Union Aviation Safety Agency has expanded its team of pilots and engineers based in Shanghai to work directly with Chinese counterparts on the C919 program. This near-permanent presence at Shanghai Pudong International Airport and surrounding test facilities is described as a shift from occasional missions to continuous oversight, underscoring a more hands-on validation campaign.

Publicly available information shows that EASA personnel are participating in ground inspections, simulator sessions and supervised flights on board C919 aircraft already operating from Shanghai. These activities are aimed at independently verifying performance, systems behavior and safety procedures under local operating conditions. The work builds on earlier technical exchanges and preliminary inspections that had taken place in Europe and China over the past several years.

Observers note that the decision to base EASA staff in Shanghai reflects both the growing scale of the C919 fleet and China’s interest in accelerating engagement with foreign regulators. With dozens of aircraft already flying for Chinese airlines, having European experts close to the production line and test fleet allows faster feedback on design documentation, configuration changes and in-service experience.

From Domestic Debut to Global Ambitions

The C919 entered commercial service in China after receiving type certification from the Civil Aviation Administration of China in 2022. Since then, the single-aisle jet has carried millions of passengers on domestic routes, particularly with launch operator China Eastern Airlines, and has begun flying select international services in Asia under Chinese approval. COMAC has steadily increased deliveries, expanded the route network and commissioned additional assembly capacity.

Despite this momentum at home, broader international deployment still depends on recognition from major Western regulators. EASA certification is a key objective because many airlines in Europe and beyond view European approval as a benchmark for safety and reliability. Published coverage notes that several potential customers in regions such as Southeast Asia, the Middle East and Africa closely monitor EASA’s progress when evaluating new aircraft types.

For COMAC, a successful European validation would signal that the C919 can compete more directly with the Airbus A320neo and Boeing 737 MAX families, which dominate the global narrowbody market. It could also strengthen China’s role in the aviation supply chain, encourage more international partnerships and support the country’s long-term ambition to become a major exporter of commercial jets.

Flight Tests Mark a New Certification Phase

Reports from aviation news outlets describe a series of verification flights flown from Shanghai by EASA test pilots in cooperation with COMAC crews. Initial evaluation flights reportedly took place in late 2025, followed by additional sorties and system checks in early 2026. These flights are considered a central element of the agency’s validation program, confirming that the aircraft performs as documented across a range of operating scenarios.

During these campaigns, European pilots typically assess handling qualities, flight control logic, cockpit ergonomics and the behavior of critical systems such as avionics, navigation and communications. Data generated from the flights is then cross-checked against the technical dossier submitted by the manufacturer and against standards in European airworthiness regulations. Any discrepancies can lead to requests for modifications, further analysis or additional test conditions.

Specialists following the program note that this progression from document review and simulator checks to extensive real-world flying indicates that EASA’s evaluation has reached a more advanced stage. At the same time, the work is resource-intensive and likely to continue for several years, particularly as COMAC refines software, introduces incremental upgrades and expands the aircraft family with stretched or re-engined variants.

Timelines, Challenges and Geopolitical Crosswinds

Even as testing in Shanghai accelerates, expectations for near-term European approval remain cautious. In public comments reported in 2025, EASA’s leadership suggested that full certification of the C919 could take three to six years from that point, placing a potential decision closer to the end of this decade rather than in the mid-2020s. Analysts interpret this as a signal that validation of a new large commercial jet from a non-Western manufacturer is inherently complex.

Technical hurdles include the need to assess a wide range of Western-sourced components integrated into the C919, such as engines, avionics and flight-control systems, within a Chinese-designed airframe and software architecture. Supply chain shifts and export controls on sensitive technologies add further layers of scrutiny and, in some cases, may require alternative equipment to be evaluated and certified.

Geopolitical tensions also influence the pace and tone of cooperation. Commentaries in European and Asian media highlight that aviation has become intertwined with broader trade and technology discussions between China, the European Union and the United States. While regulators insist that safety remains the sole criterion for certification decisions, the broader environment can affect how quickly technical questions are resolved and joint test campaigns are scheduled.

For now, observers describe a dual-track strategy in Beijing and Shanghai: expanding domestic deployment to build operating experience and economies of scale, while simultaneously working through the detailed requirements of European validation. That approach is intended to ensure that, whenever a European decision is ultimately reached, the aircraft will already have a solid record of service.

Implications for Airlines and Travelers

For European airlines, the intensified testing in Shanghai presents both an opportunity and a question mark. On one hand, a successfully certified C919 could eventually give carriers an additional option in the busy short and medium haul segments, potentially increasing competition in purchase negotiations with Airbus and Boeing. On the other hand, the lack of a firm certification date makes it difficult for airlines to plan fleet strategies around the Chinese jet in the near term.

Travelers are unlikely to notice immediate changes on European routes, since the C919 remains confined to Chinese and select regional networks while the certification effort continues. However, if EASA ultimately grants approval and early European customers emerge, passengers could later see the aircraft appearing on flights within Europe or on connections to China and other parts of Asia.

In the meantime, the most visible impact will be in Shanghai and across Chinese skies, where an expanding C919 fleet is already reshaping the domestic aviation landscape. The presence of European test crews on the ground adds an international dimension to that story, turning everyday flights into data points in a broader campaign to prove that China’s first modern mainline airliner can meet the world’s most demanding regulatory standards.
