## Discrepancy

IN-FLIGHT ENGINE SHUTDOWN,  FLIGHT 8850, TLH-MEM. ON THE VISUAL APPROACH TO RUNWAY 27 AT KMEM, THE CREW OBSERVED THE NO. 1 ENGINE TORQUE INDICATION BECOME ERRATIC, THEN DROP TO ZERO, ACCOMPANIED BY AN UNCOMMANDED LEFT ROLL. MEMORY ITEMS WERE ACCOMPLISHED, AND THE CREW SHUT DOWN THE NO. 1 ENGINE AND FEATHERED THE PROPELLER. AN EMERGENCY WAS DECLARED WITH ATC. THE CREW CONTINUED FOR THE LANDING AND COMPLETED A SINGLE-ENGINE LANDING ON RUNWAY 27 WITHOUT FURTHER INCIDENT. ONCE CLEAR OF THE RUNWAY, THE ENGINE WAS SECURED USING THE QRC/QRH. AIRPORT RESCUE/FIRE PERSONNEL REPORTED NO FIRE OR SMOKE OBSERVED, AND THE AIRCRAFT TAXIED IN AND PARKED.
