As far as I can tell, the allegations of the LEAP-1C's inferiority originated from dubious sources. Wikipedia had cited baseless speculation from a Forbes article, which never presented any actual evidence. If you have more reliable sources than these, I'd like to hear about them.

The allegations of the LEAP-1C's inferiority was previously refuted by taxiya in the C919 thread. But that was last year, so I don't know if there has been any new information since then.

thanks for the correction.. i actually don't know much about LEAP-1C in context with C919. i read it on google.

I've actually heard that the LEAP-1C is the most advanced of the three, but I forgot in terms of what (could be power trans).

Nearly all of the foreign components are JV with factories in China. There was a list discussed here at SDF that showed a local firm for every part. Pretty obvious they are preparing for the worse.

That's good then. The question is if all western companies involved in the project have to pull out from the joint ventures can the chinese still carry on producing those products effectively? Hopefully the chinese partners have access to all the most sensitive core tech of the components and products they are producing under licence and joint venture. Though i know its rare for countries to provide their full core technologies to others they often keep the core/sensitive areas to themselves which is normal to be honest.

Most of the avionics and other components for civilian airliners are not that technically out of reach for China -- with the exception of the engine. Depending on how the CJ1000/2000 are progressing, there might not that much out of reach even for engines.

The biggest issue is certification. I doubt China has a lot of issues with the basic tech undercarriage or the radar. But the West have certified firms supplying all these sub-systems for decades. Unless COMAC is embargoed they would obviously want to slowly phase in local suppliers instead of having to do it all at once.

Everything is really a test of time and the rising count of numbers. Enough flights with the C919 and later the C929 and C939, China will work in domestic players in the whole eco-system.
