China Expands Repair Network for C919 and C909 Jets Amid Supply Challenges

China Expands Repair Network for C919 and C909 Jets Amid Supply Challenges
Strengthening Maintenance Capabilities for Domestic Aircraft
China is broadening the repair and maintenance network for its domestically developed airliners, notably the C919 and C909 series, to support critical components such as engines and landing gear. This development coincides with the Commercial Aircraft Corporation of China (Comac) increasing jet deliveries and operators expanding flight operations, creating a pressing need for enhanced support infrastructure across mainland China and Hong Kong.
Industry experts emphasize that the expansion of maintenance, repair, and overhaul (MRO) providers is vital for the resilience of China’s aviation sector, particularly in the face of ongoing global supply chain disruptions. Jason Zheng, an analyst at Shanghai-based consultancy Airwefly, noted that a more extensive domestic support network improves the prospects for these indigenous aircraft to withstand external supply challenges as operational demands rise.
Key Partnerships and Milestones
A significant milestone was recently achieved by Hong Kong Aircraft Engineering Company Limited (HAECO), a leading global aircraft servicing firm under the Swire Group. HAECO completed its first overhaul of a C909 regional jet’s landing gear in Xiamen, Fujian province, marking an expansion of its service portfolio to better support regional jet operators both within China and internationally. The C909, with over 180 units currently in service, is the first Chinese aircraft to operate flights across Southeast and Central Asia and is utilized by foreign carriers including Indonesia’s TransNusa, Vietnam’s VietJet, and Lao Airlines.
In July 2025, HAECO formalized agreements with Comac and multinational supplier Liebherr to provide repair and maintenance services for both the C909 and C919 models. This builds on an existing partnership between HAECO and Comac aimed at delivering comprehensive airframe, engine, and component support to Comac’s domestic and global customers.
Industry Challenges and Competitive Dynamics
The expansion of China’s MRO network occurs amid significant challenges facing the global aviation maintenance sector. According to a recent Oliver Wyman survey, the industry is experiencing a “super cycle” of increased spending driven by fleet growth and the need for heavy maintenance on aging aircraft such as the Boeing 737NG and Airbus A320. However, this surge in demand is accompanied by labor shortages, material constraints, and rising costs, which threaten to strain the existing supply chain.
Compounding these challenges, the C919’s CFM Leap engine is approaching its tenth anniversary. While confidence remains high regarding its performance, experts have expressed concerns about a potential oversupply of spare engines and the necessity to expand maintenance capabilities, as discussed in a recent Aviation Week podcast.
International competitors are also positioning themselves to capitalize on China’s evolving aviation market. Brazilian manufacturer Embraer, for instance, views its E2 jets as a complementary offering to China’s homegrown models, intensifying competition and underscoring the critical importance of a robust and resilient support network.
As China’s aviation industry continues its rapid growth, the development of a comprehensive repair and maintenance infrastructure will be essential to maintaining the reliability and competitiveness of its indigenous aircraft amid persistent global supply chain and industry pressures.
