Aircraft
During descent we received a PITCH MISTRIM message on the PFD. The Captain then disconnected the autopilot to fix the problem. He stated that the elevator trim was stuck and would not move. He then called for an emergency checklist. I then ran the emergency check for Jammed Elevator Trim. We declared an emergency with ATC; notified the passengers of the situation; and then landed uneventfully at our destination. Passengers left and we wrote up the aircraft.
Monitoring pilot ran the appropriate emergency checklist which resulted in autopilot being turned off. At that time; I (pilot flying) was unable to move the elevator trim. It was frozen in a nose down position. At all times; the aircraft was under control and stable. We then proceeded to notify ATC and declared an emergency. We landed uneventfully and upon shutdown; we were met by Airfield Rescue and Fire Fighters and debriefed them of the reason for the emergency.
A CE560XL PFD alerted PITCH MIS-TRIM so the emergency checklist was completed; an emergency declared and; with the aircraft stable and in control; a landing was completed.
