I don’t think there have been any reported cases where US pilots dealt with similiar MCAS issues. In fact, I’ve only seen three likely MCAS repeated nose down situations: the Lion air flight prior to the crash, the Lion crash, and the Ethiopian crash. There was only one report I’ve seen in the NASA database related to the MAX going nose down. However, it doesn’t even appear that event was related to MCAS, as MCAS supposedly is only enabled in manual mode, and that situation happened when the plane was in autopilot. Further, the plane only dove once, not repeatedly as in Lion and Ethiopian.
