Sounds like a FBW malfunction since J-10C is so new...A J-10C crashed on November 9, 2018, and the pilot at the age of 30 died.
It is said that, the pilot ejected himself while the aircraft was flying upside down at a low altitude, and then the aircraft kept flying...
The pilot can fly J-20, J-16, and J-10C.
RIP for pilot.
