this is what I wrote before when I read that article of 900 hours to 1500 hours
"AVIC Engine propaganda on overdrive. These guys are seriously shameless. Even when Liming couldn't mass produce FWS-10, they were still boasting about it on those AVIC articles.
There are plenty of commentaries on Chinese bbs that debunked this claim that Sichuan's AL-31 MRO plant was anything special. "
Go to Chinese forum and actually read what people who know about the progress of Chinese aero engine are saying about this. Most Russian and Western pieces are ignorant, but the Chinese ones embellish too much.
And when did we start taking analysis of posters like mik888 as official sources.
does this look like official or his self proclaimed online military expert (aka internet warrior) analysis.

And you believe what was written in Chinese BBS? there are as much garbage there. Ruben Johnson wrote the article about Sichuan plant that extend the life of Al31 F engine. That is a fact and not some fanboy imagination check your fact first! you the self avowed expert . We know that the guy who is the head of the maintenance plant receive public merit and award. It is not fantasy
The story of life extension is not from Liming but from Russian think thanks
What’s more, Chinese engineers have been modifying designs to improve some weapon systems. The Moscow-based Center for the Analysis of Strategies and Technologies, a private defense and foreign policy think tank, reported recently that China's military has developed a modification of the engine that powers the Su-27SK fighter jet that extends the operational life of the engine from 900 flight hours to 1,500 flight hours — a noteworthy achievement in aerospace technology.

Another thing that depot exist we have photos while back I might still have it in Imageshack website too lazy to upload it
There are 4 or 5 regiments of J 11 B flying with WS 10A engine and none of them dropping from the sky
I found the original article
China did make modification on the AL 31 engine to extend the MTBR from 900 hr to 1500 hr. Here is the article by Reuben Johnson and Photo of the facility from pakistan defense forum

China makes modifications to Russian Salyut AL-31F jet engine

Key Points
The PLAAF has developed its own upgrade for the Russian-made Salyut AL-31F jet engine
The development demonstrates that the Chinese have achieved near autonomy in supporting their fighters' Russian-made engines
The Chinese People's Liberation Army Air Force (PLAAF) has developed its own service life extension modifications for the Russian-made Salyut AL-31F engine, a Moscow-based defence and foreign policy think-tank has reported.
The modifications to the AL-31F/FN P.2 series engine increase its operational limits by more than 65 per cent - from 900 to 1,500 flight hours, according to the privately owned Centre for the Analysis of Strategies and Technologies (CAST).
The AL-31F engine is the powerplant for several types of aircraft in the PLAAF inventory: the Sukhoi Su-27 (which is also licence-produced at the Shenyang Aircraft Works as the J-11), the Su-30MKK and the Chengdu Aerospace Corporation J-10. The AL-31FN is a special derivative of the original AL-31F design that was developed by the Salyut plant in Moscow for a single-engine application to be fitted to the J-10.
The service life modifications were reportedly developed at the PLAAF Overhaul Plant Number 5719. The key to the service life extension is a specific set of improved, Chinese-made components that are part of what is described as a "re-manufacturing kit" that is introduced during the process of a full-scale remanufacturing and overhaul process.
The plant is located near the city of Chengdu in Sichuan province, employs 2,000 personnel and is reported to be a model of innovation within the PLAAF's network of repair plants. During the past several years the facility has initiated 63 different research and development programmes and has been awarded more than 20 state prizes for achievements in technological innovation. In the same time period, the plant's assets have more than doubled from CNY1.1 billion (USD147.2 million) in 2004 to CNY2.9 billion today.
The plant's officials credit the success of their overhaul process to a decision taken in 2004, when some of the first AL-31F engines were presented to the plant by the PLAAF for overhaul. A decision was taken, according to the Chinese news sources originally cited, to completely reorganise the overhaul process. This streamlining of the overhaul disassembly and servicing line resulted in a 27.3 per cent decrease in the time required to complete an overhaul and increased the plant's production capacity by 60 per cent.
This level of improvement in the engine's design demonstrates that the Chinese have achieved near autonomy in the support of these Russian-made engines. Russian specialists who spoke to Jane's state that this is "another example of how the technology sold to the Chinese during the 1990s has now been fully assimilated by them. It is only a matter of time before the engines that China produces will be as good as or better than anything designed here in Russia".

ok...perhaps the truth is in the mid point..
to be recognized, taihang & ws13 have to be in the export market.
us, uk, france & russia are there.
time will take its course for clearer pictures.
another note:
was that about ws-15 committee in 2006?
View attachment 7306
something to do with the development high thrust 10:1 ration jet engine. I believe the engine was WS-15.
