US bans engine sales affecting COMAC's aircraft range

The supply cut could significantly slow production of the Comac C919, which Beijing views as a competitor to Airbus A320 and Boeing 737 models. With only one engine option available for both aircraft types—LEAP-1C for the C919 and CF34-10A for the C909—any disruption would leave newly built planes grounded.

In response to these challenges, China is developing domestic aircraft engines through Aero Engine Corporation of China (AECC). Although progress has been slow due to new requirements like using fully domestic parts, AECC reports that “the CJ-1000 engine is undergoing trial runs” with promising results. Originally slated for service by 2020 but delayed until 2030 due to certification processes expected by 2027.

Collins Aerospace supplies various systems essential to both aircraft models: development simulators; passenger door actuation; exterior lighting; ice protection/prevention equipment; pilot controls; fire/overheat protection systems; power distribution equipment; electric power generation systems—all vital components necessary even beyond just propulsion units alone when considering comprehensive
