China’s C919 Jet Faces Production Delays: Engine Issues Threaten Domestic Aircraft Independence Amid U.S. Pressure

China’s flagship C919 large passenger aircraft, developed to compete with Boeing and Airbus models, continues to face significant production and delivery challenges in 2026, with its progress heavily constrained by unresolved engine supply issues and geopolitical tensions. Despite ambitious targets, only three C919 jets were delivered in the first three months of this year, a sharp slowdown that underscores the aircraft’s reliance on imported engines and the broader hurdles in China’s push for aviation self-sufficiency.

The core bottleneck lies with the CFM International LEAP-1C engines, which power the C919. The suspension of exports from CFM—a joint venture between GE and Safran—mid-2025 exacerbated supply chain disruptions, forcing China’s Commercial Aircraft Corporation (COMAC) to restructure its procurement and production strategies. COMAC has since delivered only 15 C919 jets in 2025, far below its initial target of 75 and even missing the revised goal of 28 aircraft. Internal workforce shortages and delays from foreign suppliers have further compounded the challenges, pushing COMAC to reassess its supply chains and seek alternative solutions.

China’s long-term ambition to reduce its dependence on foreign technology is centered on the development of indigenous aircraft engines, particularly the CJ-1000A and CJ-2000 turbofan engines. While the CJ-2000, designed for the upcoming C929 widebody aircraft, has achieved a significant thrust milestone of 35.2 tonnes, the path to producing a reliable, large-scale commercial engine remains fraught with technical and logistical hurdles. The CJ-1000A, intended for the C919, is still under development and has not yet reached operational readiness, leaving the aircraft dependent on Western engines for the foreseeable future.

Analysts warn that the delay in engine development and the ongoing reliance on foreign suppliers could hinder the C919’s commercial viability. The aircraft’s success hinges on resolving these bottlenecks, but the timeline for achieving full self-sufficiency in engine production remains uncertain. For now, COMAC is scrambling to secure Western-made engines while accelerating the development of its domestic alternatives, a strategy that reflects the broader geopolitical and technological pressures shaping China’s aviation industry.

As the C919 program struggles to regain momentum, the stakes are high. With over 1,000 C919s on order, China’s ability to deliver on these commitments will determine its standing in the global aviation market and its progress toward reducing reliance on foreign technology. The coming years will be critical in determining whether China can overcome these challenges and establish itself as a major player in large commercial aircraft production.
