Don’t know if the 190 suffered from the same issue as the 145 series, but being that they where probably light weight and high thrust TO, I wonder if they flew out of the trim motor’s capabilities.
Eagle Flight 230 out of ORD back in late 2000 or 2001. Have a read of that accident report. The ATC tape with radar data is floating around as well. Very similar with gyrations and several climbs and descents trying to control the aircraft. FAA almost grounded the type since after powering down all components worked just fine and “could not duplicate”.
Basically, crew late to trim the stab after TO, the control force by then strong enough to disable the main trim. Crew quick to try the standby trim, before reducing airspeed to reduce control load, so now standby trim also disabled. The 145 series ended up with a placard to ensure trimming after takeoff before getting too fast.
