FIRE WARNING ON B727 RESULTS IN EMER DECLARATION AND LNDG. NO PROBS FOUND.

Narrative

ON DEP WE NOTED AN ODOR WHICH WAS SOMEWHAT SIMILAR TO CHICKEN SO WE THOUGHT THERE MIGHT HAVE BEEN A BIRD STRIKE. THE ODOR DISSIPATED QUICKLY AND ALL ENG INSTS APPEARED NORMAL SO WE CONTINUED TO LEX. ABOUT 10 MINS OUT OF LEX THE ENG #2 FIRE HANDLE ILLUMINATED ACCOMPANIED BY THE BELL. THE FIRE DETECT SYS WAS IN B MODE AS THE A MODE WAS DEFERRED. WE FOLLOWED THE ENG FIRE PROC. THE ENG WAS SHUT DOWN AND BOTH FIRE BOTTLES WERE USED. THE FIRE HANDLE EXTINGUISHED ABOUT 2 MINS BEFORE LNDG. WE DECLARED AN EMER AND REQUESTED THE EMER EQUIP MEET US ON LNDG. THE FLT ATTENDANTS HAD ABOUT 10 MINS TO PREPARE. I MADE SEVERAL PA'S AND DESCRIBED THE SIT AS AN INDICATION THAT IT WAS A LITTLE HOT AROUND ONE OF OUR ENGS. I ALSO NEVER MADE A PA SAYING WE HAD SHUT DOWN THE ENG. I DID ADVISE THE PAX THAT THERE WOULD BE EQUIP MEETING US WHICH HAD FLASHING LIGHTS AND WE WOULD BE STOPPING ON THE RWY FOR THEM TO INSPECT US BEFORE WE TAXIED IN. I MADE ONE FINAL PA ON APCH. APCH AND LNDG WERE UNEVENTFUL. WE STOPPED ON THE RWY; OPENED THE COCKPIT DOOR AND MADE A PA AS THE EMER PERSONNEL INSPECTED THE ACFT. I TALKED DIRECTLY TO THE FIRE TEAM LEADER AND EXCHANGED INFO. HE STATED HE HAD AN IR SENSOR WHICH INDICATED ENG #2 WAS COOL WITHOUT ANY HOT SPOTS AND ALSO THERE WERE NO EXTERNAL INDICATIONS OF FIRE. AFTER INSPECTION WAS COMPLETE WE MADE A PA AND TAXIED TO THE GATE. THE NEXT MORNING WE DISCUSSED THE SIT WITH MECHS PRIOR TO DEPARTING. MAINT FOUND NO INDICATION OF FIRE; EXCESSIVE HEAT; OR BIRD STRIKE.
