## Discrepancy

AFTER TAKEOFF, BOTH CREW NOTICED A "DIFFERENT" SOUND FROM ENGINES.  ACFT SOUNDED LIKE MAY HAVE HAD A COMPRESSOR STALL BUT WE HAD NORM ENG INDICATIONS.   AT 200' RECEIVED AN ENGINE FIRE LIGHT ON ENG NR 2.  AFTER ABOUT 15-20 SEC.  WARNING WENT OUT AND RECEIVED AN  ENG 2 LOOP A FAULT.  ELECTED TO DIVERT, ABOUT 5 MINUTES, RECEIVED A LOOP B FAULT ON ENG 2.  PERFORMED VISUAL INSPECTION IAW FIM AND SENT DOWNLOAD DATA TO ENGINEERING.  NO ABNORMAL OPERATION OF ENGINE FOUND.  TIGHTENED B LOOP, REPLACED A LOOP AND REPLACED FDCU.  OPS CHECKED GOOD.
