Pardon me, do you have an article on this?
COMAC C919
- Thread starter Deino
- Start date
as per the latest AECC statement, '' it is not possible to replace all LEAP engines with CJ-1000A. this is just an alternative option in order to secure supply line. CJ-1000A exceed all the parameters during evaluation and testing. and soon Engine will be mounted on C919 wings for final test
Sorry but this leads directly to Guancha site's main page. Do you happen to know the title (in Chinese) of the article you are referring to?
i have edited it with SCMP article just refresh this page, original Guancha article has been taken down.
CJ-1000 engine has been flying on Y-20 test aircraft for quite some time.
It shouldn't take over one year to go from that event to putting it on the C919 for test flights there. But then again when has Chinese engine development ever been smooth in the first place.

Engine development can be very smooth and first time certification can still be very time consuming.
Well, you can always accelerate testing and development like Russia is doing. They put the PD-8 into the SJ-100 for test flights before it was certified. They use three aircraft, one with Western components but Russian engines, one with Russian components, but Western engines, and the third is all Russian.
This means you can start more advanced testing earlier. They are flying with the PD-8 on two prototype aircraft and it is only expected to be certified late this year.
At this point CJ-1000 has been air tested for two years. They should just put it on a C919 and conduct flight tests in it. How is development of the engine nacelle and pylon, plus software integration with the C919 is the question.

China has much more stringent testing standards than Russia does.
It is going to delay the project further then. The Russians won't start serial production until all the testing is done either. They just do concurrent testing to speed things up. It makes testing more complicated and risky, but this is with test pilots not passengers.
CJ-1000A should either be already flight certified or very soon as AECC reps were talking about how they are going to start trials with CJ-1000A on C919 soon which with this recent development could be as soon as late this year IMO if they decide to speed up the process. It's been on the Y-20 testbed for years now.
