## Discrepancy

THIS CAUSING THE AIRCRAFT TO START SURGING TO THE RIGHT.  NUMBER TWO ENGINE WAS SHUTDOWN.  AN IN-FLIGHT EMERGENCY WAS DECLARED.  THE AIRCRAFT LANDED AT AUGUSTA WITH NO OTHER PROBLEMS.  MAINTENANCE FROM CHARLOTTE MOVED THE TORQUE SIGNAL CONDITIONER FROM BRIDGE TWO TO BRIDGE ONE.  MAINTENANCE GROUND RUN THE AIRCRAFT AND MADE ADJUSTMENTS TO THE SIGNAL CONDITIONER.  AIRCRAFT GROUND RUN AND OPS CHECKED GOOD.  AIRCRAFT WAS RETURNED TO SERVICE.
