It was three years ago, I feel pretty sure it is a working engine

Yes, I think the engine should be in pre-production status now.
They need to log in a few thousand flight hours with CJ1000A on one or a few of the six C919 prototypes to smooth out any possible bugs, and also to set up engine production lines with all tools in place and the need to have a pilot production run to verify manufacturing methods work efficiently as designed.
I believe they have this plan B since Trump's first term. The Leap-1C engine stockpile will help to buy time for introduction of CJ1000A on C919.
It looks like, China could also sanction the US for Leap Engine parts.
别再拿1819年那会老谣言来黑长江1000了， 长江1000供应商都是公开的，全自主，碳纤 维风扇扬州新扬，压气机无锡航亚，燃烧室航 发-北航设计（生产应该是应流/无锡透平），
高压涡轮无锡透平/安徽应流，低压涡轮太仓 华钛瑞翔，当然我这个按部位分并不准确，因 为并不一定完全是一个厂商完全生产一个部位 所有零件，但主要生产商就是这几个公司，剩 余其它部分例如fdec，碳纤维外壳什么就不多 说了，没上述的难度高但肯定是自主， cj1000就是完全自主生产的发动机，别再那 什么压气机德国燃烧室美国设计在那黑了，纯
搞笑，西方人是不会给我们这么搞得。
花了6块大洋的昵称LVE 科普一下吧，CFMLEAP-1C发动机也不完全 是美发零部件。其压气机叶片的供应商是江苏 航亚。而江苏航亚一直是GE和RR的一级供应 商。CJ-1000的压气机叶片也是江苏航亚供应
的。 还有一家公司，叫应流集团，总部位于安徽， 他家的特长是生产高温涡轮叶片静叶，机匣 等。也是GE和RR的一级供应商。这家公司也
是CJ-1000的供应商。 CJ-1000和LEAP-1C除了燃烧室，他们的供
应商很多都是差不多层次的。
Don't use the old rumors of 1819 to discredit CJ 1000. CJ 1000 suppliers are all public, fully autonomous, carbon fiber fan Yangzhou Xinyang, compressor Wuxi Hangya, combustion room Hangfa-Beihang Design (production should be Yingliu/Wuxi Tuoping),
High-pressure turbine Wuxi Tuoping/Anhui Yingliu, low-pressure turbine Taicang, Huati Ruixiang, of course, my division is not accurate, because it is not necessarily a manufacturer that completely produces all parts of one part, but the main manufacturers are these companies, and the rest of other parts such as fdec, carbon fiber There is not much to say about the shell. It is not as difficult as above, but it must be autonomous. cj1000 is a completely self-produced engine. Don't do it. What kind of compressor German combustion chamber American design is black there, pure
Funny, Westerners won't do this to us.
The nickname, Spent 6 Sliver Dollars, Show some common sense. The CFM LEAP-1C engine is not exactly a hairdressing (Great Google Translation for American Engine) part. The supplier of its compressor blades is Jiangsu Hangya. Jiangsu Hangya has always been a first-class supplier of GE and RR. The compressor blades of CJ-1000 are also supplied by Jiangsu Hangya.
There is also a company called Yingliu Group, headquartered in Anhui. Its specialty is the production of high-temperature turbine blades, static blades, boxes, etc. It is also a first-class supplier of GE and RR. This company also
It is the supplier of CJ-1000. CJ-1000 and LEAP-1C except for the combustion chamber, their supply
Many of the quotients are at the same level.

Love to see how this plays out! MAD in manufacturing!
Here's a translation that uses common vocabulary while accurately conveying the technical and emotional content:
Stop using those outdated 2018/2019 rumors to criticize the CJ1000. The CJ1000's suppliers are publicly known, and it's fully developed and produced within China. Here's a breakdown (though simplified, since one company doesn't necessarily make just one part):
- Carbon fiber fan: Xinyang Yangzhou
- Compressor: Hangya Wuxi
- Combustor: Designed by Aero Engine Corp. of China (AECC) and Beihang University (Production likely by Yingliu / Wuxi Turbine)
- High-Pressure Turbine: Wuxi Turbine / Anhui Yingliu
- Low-Pressure Turbine: Huatai Ruixiang Taicang
Let me explain something: even the CFM LEAP-1C engine isn't made solely with US parts. Its compressor blades come from Jiangsu Hangya, which is a tier-1 supplier for GE and Rolls-Royce. Hangya also supplies the CJ1000 compressor blades.
Another company, Yingliu Group (based in Anhui), specializes in high-temperature turbine stator blades, casings, etc. It's also a tier-1 supplier for GE and RR, and it supplies the CJ1000 too.
Apart from the combustor, many CJ1000 and LEAP-1C suppliers operate at similar levels.
CJ-1000A pulsating assembly line contract won by German company ''Broetje automation'' and this company is owned by Shanghai Electric. by September, 2022 the project has completed the pre-acceptance of the workshop.
This assembly line is ''ceiling mounted horizontal automatic'' which is perfect for mass production. highly automated line.
AECC released the official promotional video of CJ-1000 in Zhuhai airshow 2021.. in this they showed a little glimpse of CJ-1000A assembly line. this is where they build pulsating assembly line later on.
all respective tools and automation equipment has put into place since late 2022.. the production line is running right now that's because CJ-1000A is in certification process you need many units for verification and testing..
all necessary preparation has completed. AECC just need to pass certification process.

C919 arrived in Nanyang for the first time. It was flying the Guangzhou-Nanyang route.
The paint job is kinda interesting. From the front it looks like the plane is laughing at you.
I really dig the colors though, and on this route, it really fits with the whole "Nanyang" theme.
What's the source of that. I did not know that Chinese companies are supplying critical components for GE and RR.
