Narrative:

We were planned to arrive in cvg on the gavnn 2 arrival. Approximately 50 miles from gavnn we were informed that there was an aircraft in front of us that reported severe turbulence at gavnn and that we would also receive severe turbulence if we continued on the arrival. I calculated fuel numbers for another arrival and ATC suggested to change to the jackie 1; so we did. During our initial descent from 24000 I informed both passengers and flight attendant about the weather ahead and to secure the cabin and fasten seat belts. At approximately 14000 we encountered moderate turbulence for around 1 or 2 minutes. Shortly after the initial moderate we encountered severe turbulence. We flew at turbulence penetration speed above 10;000 and I selected dual ignition on the engines. Shortly after the severe we started receiving variations in pitch and roll; and our autopilot kicked off. At this time we stated that we were in severe turbulence on the jackie 1 arrival. Aircraft control at this phase was nil. Approaching 11;000 the ride improved back to moderate turbulence and we were able to re engage the autopilot. The rest of the flight continued with no further special actions. Upon arriving in cvg a post flight inspection was completed and no major structural defects were noted. I debriefed the flight attendant on the turbulence situation and no passengers were injured. I elected to write up our aircraft for flying through severe turbulence and have proper maintenance inspections accomplished to ensure complete aircraft safety.
