According to the Jetliner (大飞机) magazine, which is published by COMAC, the design of AEP500 turboprop (5000+ KW or 6700+ hp) was finalized in 2021, and small-batch production has begun. The article also mentions that WJ-6E turboprop has reached an output of 6000+ hp. Both engines are available for the MA700 airliner, with the WJ-6E being the backup option. The article also confirms that MA700's maiden flight took place in April 2022, although it doesn't state which engines it flew with.

Interesting history and story about MA700. I admit I don't pay a lot of attention to MA700. Curious why they keep a low-profile on the MA700 maiden flight in April 2022. Still a lot of western dependency? But so is C919, yet C919 has been trumpeted so much and so loudly. Even AG600 seems to get a lot more publicity.
nope. MA-700 is a medium-range and a complete indigenous product except engines but those engines blocked by the Canadian government.
so MA-700 forced to choose domestic propulsion.
Just to make sure I’m not mixing it up, is the WS-10A considered the equivalent of analogue of AL-31F Series 42 (also known as AL-31FM1)?
From what I can tell, the current WS-10A has 13,200 kgf of thrust, 1,200 hour MTBO, and 2,000 hour life. When did the current WS-10A enter service or was qualified?

WS-10A had downgraded thrust due to reliability issues.
What is the current thrust of WS-10A? I was under the impression it’s 130 kN or so. Is the current service life figure of 2,000 hours and MTBO of 1,200 hours accurate? Basically I would like to know when the current WS-10A entered operational service.
We don't have very clear and reliable delineations between the various WS-10 variants in service (there are a number of variants in use), nor do we know exactly what their thrust are and certainly no clear reliable numbers for MTBOs.
The WS-10 first entered service in 2009 powering J-11B, and at the time its designation was simply called WS-10A, but since then it has been dubbed WS-10D, and frankly it is all a mess.
