## Discrepancy

THE CREW DIVERTED THE AIRCRAFT TO CHS AFTER THE NR 1 ENGINE SHOWED A MOMENTARY FIRE INDICATION, WHICH EXTINGUISHED ON IT'S OWN.  THE THROTTLE WAS BROUGHT TO IDLE AND NO EXTINGUISHING AGENT BOTTLES WERE DISCHARGED.  MAINTENANCE PERFORMED A TEST OF THE FIRE WARNING SYSTEM AND ALL CHECKS WERE GOOD.  ALL FIRE WARNING LOOP RESISTANCES ARE WITHIN MM LIMITS.  AN ENGINE RUN-UP WAS PERFORMED AND ALL PNEUMATIC DUCTS WERE CHECKED, NO TROUBLE FOUND. THE FDCU WAS REPLACED AND THE FINAL FIRE WARNING TEST WAS SATISFACTORY.
