Narrative

DURING CLB ON DEP AT APPROX 11000 FT MSL THE PURSER CALLED THE COCKPIT FROM THE AFT GALLEY INDICATING TO THE RELIEF FO THAT THERE WAS STRONG ODOR/SMOKE IN THE AREA. AS THE PF; I ASSUMED RESPONSIBILITY FOR ATC CONTACT WHILE DIRECTING THE PNF TO ACCOMPLISH THE QRC FOR GALLEY SMOKE/FIRE. AT APPROX 3-4 MINS INTO THE EVENT; THE RELIEF FO STATED THAT CONDITIONS IN THE AFT GALLEY WERE WORSENING AND THE CABIN CREW WERE 'VERY EXCITED.' AT THIS POINT; I DECLARED AN EMER WITH ATC AND REQUESTED AN IMMEDIATE RETURN TO THE ARPT FOR LNDG. A TURN WAS EXECUTED TO PLACE THE ACFT ON AN EXTENDED DOWNWIND LEG IN CLEAN CONFIGN; 240 KIAS; 11000 FT MSL. DURING THIS ACTIVITY; DISPATCH AND MAINT WERE NOTIFIED. AT APPROX 8 MINS INTO THE EVENT; THE PURSER INFORMED US THAT HE HAD POSITIVELY IDENTED THE SOURCE OF SMOKE/ODORS AS A GALLEY CART ELECTRICAL PIGTAIL CONNECTOR. FURTHER; HE STATED THAT CONDITIONS WERE RAPIDLY IMPROVING. UPON EXTENSIVE CONSULTATION WITH MAINT; DISPATCH; THE PURSER AND MY COCKPIT CREW; IT WAS DETERMINED THAT THE SOURCE OF THE PROB WAS IDENTED; UNDERSTOOD AND CORRECTED. A JOINT DECISION WAS MADE THAT THE FLT COULD SAFELY PROCEED TO DEST WHICH IT DID WITHOUT FURTHER INCIDENT. A MAINT ENTRY WAS MADE IN THE LOG AND PERSONNEL WERE DEBRIEFED AT DEST. CRM BTWN THE CABIN AND COCKPIT WERE INSTRUMENTAL AND HIGHLY EFFECTIVE THROUGHOUT.
