COMAC C919 Faces Production Delays Amid US Export Curbs

COMAC C919 Supply Chain Vulnerability

The Commercial Aircraft Corporation of China (COMAC) is facing significant operational headwinds as the U.S. government implements stricter oversight of aerospace exports. The U.S. Bureau of Industry and Security (BIS) has begun slowing the issuance of export licenses for critical components essential to the C919 program, including the CFM International LEAP-1C engines and advanced avionics systems. This regulatory pressure, exercised under the Export Administration Regulations (EAR), serves as a strategic lever in ongoing trade negotiations between Washington and Beijing. The impact on production is immediate: COMAC’s 2025 delivery target for the C919 was reportedly reduced from 75 aircraft to 15, highlighting the fragility of the jet's current supply chain.

Stakeholder Impact and Market Consequences

The restriction on Western technologies creates significant volatility for both domestic and international stakeholders. For major Chinese operators—including China Eastern, Air China, and China Southern—the production slowdown forces a reassessment of fleet expansion strategies. Simultaneously, Western suppliers face long-term market risks. CFM International, a joint venture between GE Aerospace and Safran, risks substantial losses in engine sales and aftermarket revenue should export licenses remain restricted. Furthermore, avionics providers such as Honeywell and Collins Aerospace are seeing their long-term contracts in the Chinese commercial sector jeopardized by the evolving geopolitical climate.

Aviation Import Substitution Trends

China’s current trajectory mirrors the challenges faced by Russia, where the MC-21 aircraft program encountered severe delays following Western sanctions. In 2022, Russia was forced to initiate a comprehensive redesign of the MC-21 and the SSJ-100 to incorporate domestic components, such as the PD-14 engine, after the loss of Western-sourced powerplants. This shift resulted in the postponement of commercial deliveries until 2026 or 2027. China is now pursuing a similar path of aviation import substitution, accelerating the development of the CJ-1000A turbofan engine to replace the CFM LEAP-1C. According to Shaanxi-based aviation columnist 'Evening Breeze,' while the current U.S. restrictions act as a catalyst for Chinese manufacturing independence, the transition remains a multi-year challenge characterized by significant industrial friction.

The Timeline for Domestic Certification

The path toward full domestic production is heavily dependent on the certification of the CJ-1000A engine. The Civil Aviation Administration of China (CAAC) is expected to oversee the certification process for this powerplant between 2027 and 2029. This transition is not merely a technical hurdle but a strategic response to the current export climate. Trade analysts suggest that the slowdown in BIS export approvals is linked to broader trade tensions, specifically concerning China's export controls on rare-earth minerals. Consequently, the C919 program is increasingly viewed as a barometer for the broader decoupling of the global aerospace supply chain.

Why This Matters for the Aerospace Sector

The reliance on Western-sourced components has transformed the C919 from a flagship commercial project into a focal point of geopolitical trade strategy. For the global aviation industry, this development signals a potential shift toward localized, fragmented supply chains that could alter the economics of aircraft manufacturing for the next decade. If China successfully indigenizes the C919, the market share for Western aerospace suppliers could permanently contract, fundamentally reshaping the competitive landscape between COMAC, Boeing, and Airbus.
