## Discrepancy

ILLUMINATED ENG. FIRE LIGHT, DETECTED 8 MIN INTO A PATIENT FLIGHT FROM A REFERRING FACILITY TO ANOTHER HOSPITAL. PILOT COMPLETED A PRECAUTIONARY LANDING, THE LANDING WAS UNEVENTFUL AND WITHOUT ISSUE.  THERE WAS NO EVIDENCE OF AN ENGINE FIRE AT ANY TIME.  MAINTENANCE RESPONDED AND INSPECTED THE A/C.  EMERG. LIGHT WAS UNABLE TO BE RE-PRODUCED AND NO ISSUES WITH THE SYSTEM WERE FOUND.  ON POST MAINTENANCE GROUND RUNS AND HOVER FLIGHT THE ISSUE WAS UNABLE TO BE DUPLICATED AS WELL.  AFTER THE A/C WAS RETURNED TO SERVICE, THE REPOSITION FLIGHT WERE ALSO UNEVENTFUL AND NO ISSUES WERE NOTED OR ILLUMINATION OF ANY FIRE INDICATORS.  LATER THAT EVENING ON A SEPARATE FLIGHT, THE ENGINE FIRE LIGHT ILLUMINATED AGAIN AND A SECOND PRECAUTIONARY LANDING WAS MADE.  MECHANIC REPLACED ALL 3 ENGINE FIRE DETECTORS AND RETURNED THE A/C TO SERVICE.  NO FURTHER ILLUMINATION OF THE FIRE LIGHT OCCURRED ON THE FLIGHT BACK AND THE A/C HAS BEEN RETURNED TO FULL SERVICE.
