AN ACR LGT RETURNED AND LANDED BECAUSE OF AN ENG FIRE INDICATION.

Narrative

ABOUT 3 OR 4 MINS AFTER TKOF WITH CLB PWR SET; THE FE NOTICED THE #1 FIRE DETECTION FAULT WARNING LIGHT ILLUMINATED. A FEW SECONDS LATER; THE FIRE WARNING LIGHT AND BELL FOR #1 ENG CAME ON. WE LEVELED OFF AT 5000 FT AND ADVISED ATC WE HAD A PROBLEM; REQUESTING VECTORS BACK TO EWR FOR A LNDG. I TRANSFERRED CTL OF ACFT TO FO AND CALLED FOR ENG FIRE CHKLIST. THE FE AND I RAN THE CHKLIST AND THE FIRE LIGHT WENT OUT WHEN WE REDUCED PWR ON #1 ENG. WE REQUESTED A NORMAL PATTERN BACK TO EWR WITH FIRE AND RESCUE STANDING BY. WE GAVE THEM FUEL AND SOULS ON BOARD BUT DID NOT DECLARE AN EMER. THE REASON TURNED OUT TO BE A BLEED AIR LEAK WITH NO FIRE. AFTER ACCOMPLISHING THE NECESSARY CHKLISTS; WE WERE ABLE TO LAND AND TAXI TO THE GATE WITHOUT FURTHER INCIDENT. TOTAL TIME INFLT WAS 19 MINS. MY CREW WAS VERY HELPFUL WITH RECOMMENDATIONS AND CHKLIST DUTIES. I FELT THAT I HAD TO COORDINATE AND PACE THE ACTIVITY OF CHKLISTS AND ATC DIRECTIVES. CREW COORD CONCEPTS WORK VERY WELL. I DO NOT KNOW WHY I DIDN'T DECLARE AN EMER BUT SOMEHOW IT STILL CARRIES SOME SORT OF STIGMA (NEGATIVE) IN THE BACK OF MY MIND. I WILL DO SO NEXT TIME FOR SURE.
