## Discrepancy

20 MINUTES INTO FLIGHT THE RIGHT ENGINE LOOP 1 EICAS MESSAGE CAME ON INTERMITTENTLY FOR ABOUT 10 TO 20 SECONDS AT A TIME.  ABOUT FIVE MINUTE LATER THE SYSTEM FAIL LIGHT CAME ON.  RESET IT ONCE BUT IT CAME BACK WITH BOTH 1 AND 2 LOOPS INDICATING FAILED.  DIVERTED TO STL.  REPLACED RIGHT ENGINE TS45 AND TS46 FIRE LOOPS ASSEMBLY.  SYSTEM GROUND CHECKED NORMAL OPERATION.
