C929
Overview
COMAC's planned twin-aisle wide-body program for long-haul international and regional flying. The aircraft is aimed at the Airbus A330neo and Boeing 787 class and is now being advanced as an independent Chinese program after the earlier Russia-China partnership unraveled. Air China has signed a preliminary launch-customer agreement.
In detailed design phase with active CAAC engineering reviews and preliminary wind-tunnel testing under way. At Singapore Airshow 2026, COMAC signed a letter of intent with Aviage Systems for the core avionics processing system, adding to Paris Air Show 2025 MoUs with Safran and Crane Aerospace. Fuselage manufacturer Huarui Aero is targeting first middle-fuselage delivery by September 1, 2027. Powerplant selection remains the largest open gating item, though the domestically developed AECC CJ-2000/AEF-3500 turbofan has emerged as a leading candidate after completing a full-state high-altitude bench test in February 2025, logging 3,000 cumulative test hours and a peak thrust of 35.2 tonnes (~70,400 lbf) - putting it in the GEnx-1B/Trent 1000 thrust class needed for the C929.
