## Discrepancy

(CAN) DURING CRUISE FLIGHT, THE NR 1 ENGINE LOSES POWER AND STARTED TO SURGE.  THE ENGINE WAS SHUTDOWN AND SECURED.  ACFT LANDED WITHOUT INCIDENT.  ON MAINTENANCE INSPECTION THE NR 1 CYLINDER HAD 4 BROKEN MOUNT STUDS AND THE FUEL INJECTOR LINE WAS BROKEN OFF.  NR 1 ENGINE WAS REPLACED WITH OVERHAULED UNIT, WE ARE WAITING FOR TEAR DOWN REPORT FOR THIS ENGINE.
