What happened to the second production line?

the "second line" is under way as plan. in fact, it is not the line, it is the new factory.

COMAC has two main manufactories in Shanghai, one in Zhuqiao, another in Dachang. these basements are not only for ARJ, also for C919, C929.
for the time being, the old line can make 20 ARJ a year, and 25 next year, whether the second line be open or not depending on the need.

above photoes are from Dachang basement. here are some pictures of Zhuqiao basement, you can see the differences.

:On December 28, 2009, the final assembly manufacturing center pudong base started construction on a beach overgrown with reeds. After nearly six years of hard work, the first stage of construction has been basically completed. In this 4,000-mu land (1mu=667 square meter), 12 modern assembly and manufacturing plants for civil aircraft have been built, five assembly lines of the international advanced civil aircraft department have been put into use, and some workshops and departments of Shanghai commercial aircraft corporation have opened office modes in two places.

in 2018 ,Comac final assembly manufacturing center pudong base production area phase ii (518776.2 square meters) has started too.

besides the shanghai basement, other basements in other province are also under construction.

Comac jiangxi production test flight center holds the foundation laying ceremony in nanchang high-tech zone on April 26, 2019, marking the official location of the project in jiangxi. The project, with an investment of 2 billion yuan, is mainly responsible for the interior decoration installation, painting, production test flight support, customer delivery support, maintenance and operation guarantee of domestic ARJ21 new regional aircraft. After the completion of the project, it will further promote and enhance comac's production and test flight capacity in other places, and have a positive impact on the development of civil aviation industry in jiangxi province.

On May 5, a 10,106 middle fuselage (including central wing) components of the C919 aircraft assembled by the new digital production line were successfully removed from the aircraft in xi'an aviation manufacture, marking the completion of the first aircraft production and application verification of the digital assembly line. The production line is China's most advanced digital assembly line for medium fuselage, which can meet the production requirements of C919 aircraft with high quality, high efficiency, high reliability and low cost. The production line is equipped with the digital assembly system of C919 middle fuselage and the digital posture adjustment docking system of C919 aircraft parts, completely eliminating manual posture adjustment, greatly increasing the assembly accuracy of components, shortening the pose adjustment period, and achieving efficiency increase and speed up in batch production.

Further to the above

据中国航空报4月19日报道，近日，运用全新数字化生产线完成装配的C919飞机10105架外翼盒段在航空工业西飞顺利交付，标志着C919机翼数字化装配生产线完成了首架机生产运用验证。

该生产线为目前我国建设完成的最先进机翼数字化装配生产线，以满足C919飞机高质量、高效率、高可靠性和低成本的生产要求为目标，安装了C919外翼翼盒数字化装配系统、前缘机器人自动制孔系统、活动翼面自动制孔系统，最大程度上减少手工制孔。

生产线工装采用全新的设计理念，全面运用防差错技术，符合人机工程学设计，提升了产品质量和生产效率。

C919机翼数字化装配生产线技术复杂程度高，首架运用需要对大量新技术、新方法进行验证，难度大，任务重。西飞机翼装配厂认真梳理新生产线首次运用存在的风险点，落实风险控制措施，积极开展新技术运用培训，大力推进生产线验证与优化工作，解决了翼盒自动化制孔、新型工装定位、数字化测量、工艺流程优化等两百多项技术问题，完成了生产线全流程验证，涉及三台大型数字化制孔设备、近千项工装。在复杂大部件装配中，实现了自动找正、自动制孔锪窝、自动检测、自动安装临时紧固钉等功能，完成了C919翼盒由传统装配模式向数字化装配模式的转变。

C919机翼数字化装配生产线的建设与运用，有利于缩短与国际领先飞机制造商的技术差距，对提升国产飞机的国际竞争力，推动我国航空制造业的快速发展具有重要意义。

C919 needs to upgrade to domestic engines because we won't be able to buy foreign engines in a trade war.
