## Discrepancy

THE NR 1 ENGINE WAS SHUTDOWN IN FLIGHT DUE TO BECOMING UNRESPONSIVE TO THE CREW.  THE QRH WAS COMPLIED WITH.  THE ENGINE WENT TO IDLE AND WOULD NOT RESPOND THEREAFTER.  MAINTENANCE ACCOMPLISHED A WINDMILL INSPECTION, PER B757 AMM 72-00.  ALL CHIP DETECTORS WERE CLEAR.  NO EXTERNAL OIL LEAKS.  NO VISIBLE DAMAGE TO ENGINE INLET OR EXHAUST.  NO VISIBLE DAMAGE TO THE EEC/FCU WIRING.  THE LEFTT EEC WAS REPLACED, PER B757 AMM 73-21.  THE LEFT ENGINE FUEL CONTROL WAS REPLACED, PER B757 AMM 73-21.  OPERATIONAL CHECK WAS GOOD.  NO ISSUES NOTED.
