## Discrepancy

ELEVATOR TRIM ANNUNCIATION TOOK A LONG TIME TO EXTINGUISH AFTER ENGINE START. ELEVATOR TRIM IN CRUISE FLIGHT WAS BINDING. UNABLE TO MOVE WITH AUTO-PILOT ON. SUDDEN NOSE DOWN PITCH. TRIM STABILIZED FEW SECONDS AFTER. NO LOSS IN ALTITUDE EXPERIENCED. LANDING WAS UNEVENTFUL. MAINTENANCE REPLACED THE ELEVATOR PITCH TRIM SERVO. A SUCCESSFUL OPERATIONAL CHECK FLIGHT WAS PERFORMED. AIRCRAFT WAS RETURNED TO SERVICE.
