## Discrepancy

ON APPROACH, THE CREW INITIATED A GO-AROUND.  UPON INCREASING THRUST, THE CREW EXPERIENCED SURGING AND TORQUE FLUCTUATION ON THE RIGHT ENGINE.  FOLLOWING QRH PROCEDURES THE CREW DECLARED AN EMERGENCY, SHUTDOWN THE AFFECTED ENGINE, AND COMPLETED AN UNEVENTFUL SINGLE ENGINE APPROACH AND LANDING.  IT WAS DETERMINED THAT THE DIFFICULTY WAS DUE TO A FAULTY ENGINE BLEED VALVE.  THE FAULTY ASSEMBLY WAS REPLACED AND ENGINE OPS CHECKED NORMAL.
