## Discrepancy

(CAN) ELEVATOR TRIM JAM DURING AUTOPILOT DESCENT AT 16000 FT.  AUTOPILOT WAS MANUALLY DISENGAGED.  WHEN PILOT ATTEMPTED TO TRIM THE NOSE DOWN MANUALLY, IT WAS DISCOVERED THAT THE TRIM WHEEL HAD JAMMED.  PILOT STILL HAD FULL PITCH AND ROLL CONTROL WITH THE YOKE, JUST NO ELEVATOR TRIM.  SUCCESS LANDING.  NTSB ARE INVESTIGATING.
