This ia an old news update, repost for benefits of new members and others who are not following COMAC news. Looks like the instability of foreign supply chains is affecting production rate of C919. Airbus and Boeing are also facing the same problem.
根据中国商飞公司在今年三月份供应商大会上公布的计划，C919计划2024年交付30架，2025年交付54架，2026年交付84架，2027年交付110架，2028年交付126架；国产大飞机C919将真正的进入大规模量产、批量化交付和规模化商业运营的新阶段。
According to the plan announced by COMAC at the supplier conference in March this year (2024), the C919 plans to deliver 30 aircraft in 2024, 54 aircraft in 2025, 84 aircraft in 2026, 110 aircraft in 2027, and 126 aircraft in 2028; The domestic large aircraft C919 will truly enter a new stage of mass production, mass delivery and large-scale commercial operation.
中国商飞为了应对即将到来的大规模量产和交付挑战，已经做好了准备。今年8月，C919大型客机第二总装厂选址确定为上海浦东临港片区，总建筑面积约33万平方米，项目总投资达119.5亿元。建成后，总装厂将满足C919客机的批量化生产需求，预计到2027年生产线满负荷运转时，产能将达到150架以上。
COMAC is well prepared for the upcoming challenges of mass production and delivery. In August this year, the site of the second assembly plant of C919 large passenger aircraft was determined to be the Lingang area of Pudong, Shanghai, with a total construction area of about 330,000 square meters and a total investment of 11.95 billion yuan. After completion, the final assembly plant will meet the mass production needs of C919 passenger aircraft, and it is expected that by 2027, the production capacity will reach more than 150 aircraft when the production line is running at full capacity.
不过这两年航空供应链市场的不稳定性为C919的生产制造遗存潜在“雷区”，波音和空客也都因为供应链进展面临飞机推迟交付的困境，C919的部分核心部件和分系统也是由国外厂商生产和供应，因此郭佳指出，截至目前，919并未进入量产，通常年产30架左右来作为量产判断依据。919作为第一代机型，虽然已经商用，但也需要商载运营来确认可靠性。供应链的不稳定是波音、空客和商飞共同的难题，从本质上解决需要919持续提升国产化率，尤其是核心部件的国产化.
However, the instability of the aviation supply chain market in the past two years has left a potential "minefield" for the production and manufacturing of C919, Boeing and Airbus are also facing the dilemma of delayed delivery of aircraft because of the progress of the supply chain, and some core components and subsystems of C919 are also produced and supplied by foreign manufacturers, so Guo Jia pointed out that as of now, 919 has not entered mass production, and usually produces about 30 aircraft per year as the basis for mass production. Although the 919 is the first generation of the aircraft, it has been commercially available, but it also needs to be operated commercially to confirm reliability. The instability of the supply chain is a common problem for Boeing, Airbus and COMAC, and in essence, the solution requires 919 to continue to improve the localization rate, especially the localization of core components.
