When you say "jointly" developed with Safran, how jointly? Can China build the entire engine on its own? How does its MTBO compare to other engines in its class? And can that figure be taken as a proxy for indigenous Chinese turboshafts like WZ-10 and WZ-9?

I don't know the nature of the joint partnership or whether China has the ability to independently produce the engine as of right now, but I suspect the aim is to have independent production.

I also have no answer to your second question. I'm entirely unfamiliar with turboshaft industry and what constitute cutting edge maintainability parameters. Other members surely will be better able to answer that.

WZ-9 and WZ-10 are Chinese military projects. While I'm not discounting the possibility of cross-pollination, but given the timelines of their development, I doubt WZ-16's MTBO numbers can be taken as a proxy for WZ-10 and WZ-9, especially WZ-9, which is much older tech.

AC352, also known as Z-15, has been awarded an official approval certificate by the Civil Aviation Administration of China. It is now cleared to enter service.

AC352 is equipped with WZ-16 turboshafts jointly developed with Safran of France. The take-off weight is 7.5 tons, the maximum range is 850 kilometers, and it can carry 16 passengers. It features a 4-axis digital automatic flight control system, advanced glass cockpit, and highly integrated avionics. Rotors and fuselage have a lifespan of 20,000 hours. MTBO for the engines and transmission is around 5,000 hours.

WZ-9. It's also jointly built with Safran, so not 100% Chinese production.

WZ-9 turboshaft engine independently developed by China, derived from WZ-8 core machine. which is produced with Safran under joint venture. so WZ-9 has nothing to do with Safran. its improved variant already under production but specifications are not available.

WZ-16 derived from Ardiden3, basically its variant. indeed all basic R&D done by Safran but this engine is just a long commitment of French engine maker with Chinese mainland. production agreement signed with Harbin Dong'an Engine(Group) Corporation. they have shared all iPs with them. assembled in Harbin main production plant.
