China’s C919 jet faces turbulent skies as US-China trade tensions add to delays

China's C919 passenger jet program, intended to challenge Boeing and Airbus, is facing significant delays and delivery shortfalls due to escalating US-China trade tensions. The state-owned COMAC's heavy reliance on critical Western-sourced components, particularly US-controlled engines, renders its supply chain vulnerable to export restrictions and geopolitical shifts, directly impacting production schedules and hindering its ability to meet ambitious targets. Moreover, the C919's global expansion is constrained by a lack of international certification and increasing competition from Airbus within China, indicating a prolonged challenge for the program to establish itself beyond domestic markets and break the existing duopoly.

Analysis

China's C919 passenger jet program, led by state-owned COMAC, is experiencing significant turbulence and delivery shortfalls, primarily due to escalating US-China trade tensions. COMAC delivered only 7 C919s as of October this year, against a 2025 target of 30, largely because its supply chain is highly vulnerable to export restrictions, relying on 48 U.S. and 26 European major suppliers.

The program's dependence on Western components, particularly the LEAP-1C engines jointly built by GE Aerospace and Safran, has directly impacted delivery schedules, as evidenced by the U.S. suspension of export licenses earlier this year. This reliance exposes COMAC to policy decisions beyond its control, hindering its ability to ramp up production effectively, while China's alternative CJ-1000A engine remains under testing.

Despite substantial domestic demand for 9,570 new aircraft by 2044, the C919's global expansion is severely constrained by a lack of international certification from U.S. and E.U. aviation regulators, a process that could take years. This limitation, coupled with increasing competition from Airbus, which is expanding its A320 manufacturing capacity in China by 2026, suggests COMAC will struggle to break the Boeing-Airbus duopoly in the near term, with analysts anticipating growth primarily within China and regional exports by the late 2020s.

Key Decisions for Investors

• Closely monitor US-China trade policy and export control developments, as they directly impact the C919 program and its Western suppliers.
• Assess the revenue exposure of aerospace component manufacturers like GE and Honeywell to COMAC's C919 program, given the persistent production and delivery challenges.
• Maintain a favorable outlook on established aerospace manufacturers like Boeing, as COMAC's struggles reinforce the existing duopoly in the global commercial aircraft market.
• Recognize that COMAC's C919 will primarily serve the domestic Chinese market and regional exports for the foreseeable future, limiting its immediate global competitive threat.
