The 4th C919 for China Southern Airlines spotted with the tail #B-002S (and also the 1st or 2nd C919 built for 2025, see below post).

What is taking COMAC so long?At this delivery rate, it is not going to finish current contracts until well into 2040s.

Also, what do you all think about the likelihood of Trump cutting engines and other parts supplies to C919, halting the program temporarily? Pretty much a 180 degrees reversal compared to during his first term, when he supported the C919 program for buying US-made parts?

Perhaps in part the low production rate is a way to indicate the C919 project until sufficient indigenisation can occur (CJ1000, etc.). China should definitely be preparing for a US and maybe even European ban. It would be prudent to do so, even if a ban doesn't come immediately (for greater profits, etc.).

Possibly working with Russian (MC-21, SJ-100) suppliers could reduce the risk of a ban and bridge the ability of Chinese suppliers to assist.

Are people not aware China is having a historic ramp-up of military aviation production? A well-known civil aviation insider/influencer appeared on Shilao's podcast last year after touring COMAC and stated the bottleneck for C919 production was domestic rather than imported components. Domestic suppliers were prioritizing defense contracts which were more lucrative.

A fully domestic C919 is expected to begin certification in 2028 and the process is expected to take four years.

If there were a sudden U.S.-EU ban on C919 akin to the semiconductors cutoff, has anyone heard of any Plan Bs for fully domestic C919?

WS-20 is already being used on Y-20. they'd lose billions in business not only to China but to a huge portion of the world, to slightly increase specific fuel consumption by ~10% for a fleet of 22 aircraft and maybe a little bit more cabin noise.

Why are you talking about WS-20 when CJ-1000 is already a thing? In the event of a ban, they would just speed up the certification/deployment process.
