COMAC announced the completion of the first static strength test for the C919's airframe in December 2020.

中国商飞宣布于2020年12月完成C919机身的首次静强度测试。

The C919 is China's first homegrown large passenger aircraft, manufactured by the Commercial Aircraft Corporation of China (COMAC).

C919是中国首架国产大型客机，由中国商用飞机有限责任公司制造。

As of January 2023, the number of orders for the C919 jetliner had reached 1,200, according to COMAC Vice President Zhang Yujin.

据中国商飞副总裁张玉金介绍，截至2023年1月，C919客机的订单数量已达到1200架。

In December 2017, COMAC announced the successful completion of the second C919 aircraft's first long-haul flight, lasting 2 hours and 23 minutes.

2017年12月，中国商飞宣布成功完成第二架C919飞机的首次长途飞行，飞行时间为2小时23分钟。

The Chinese built COMAC ARJ21 also has the same, while the main  landing gear of the A220 is also uncovered.

中国制造的中国商飞 ARJ21 也有同样的东西，而 A220 的主起落架也被揭开。

Some smaller aircraft have engines mounted  on the fuselage tail, including, for example, the Embraer ERJ family and  the COMAC ARJ21 regional jet.

一些较小的飞机在机身尾部安装了发动机，例如，Embraer ERJ 系列和 COMAC ARJ21 支线喷气式飞机。
