## Discrepancy

DURING CRUISE FLIGHT, CREW NOTED THE NR 1 ENGINE OVERHEAT INDICATION ILLUMINATED.  CREW SHUT DOWN THE NR 1 ENGINE AND PULLED THE FIRE HANDLE UP.  THE OVERHEAT INDICATION THEN EXTINGUISHED.   CREW LANDED IN HNL WITHOUT FURTHER INCIDENT.  MAINTENANCE FOUND THE NR 1 ENGINE LOWER FIRE LOOP PINCHED BY THE GENERATOR AIR DUCT AND REPLACED THE LOOP PER AMM 26-11-11.  THE SYSTEM OPERATION CHECK WAS SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
