-Turkish 737 AMS
-FlyDubai 737 RVI
-EK 777 Dubai

Thanks

I wouldn't entirely classify the Amsterdam 737 accident as the crews fault. The primary cause was a faulty radar altimeter that provided an erroneous signal to the autothrottle that retarded the thrust levers. The crew manually advanced the thrust levers, but because he didn't disengage the autothrottle, the computer again retarded the thrust levers.

You could also include China Airlines 006 in that, after an engine rollback, they failed to monitor their airspeed, resulting an a departure from controlled flight. Again, an underlying issue occurred, mode confusion was not the primary reason.
