Narrative:

B737-300 cleared for takeoff runway 12R at msp. Flight attendant calls cockpit on interphone stating she smells electrical smoke from forward galley oven. One side was on mco (maintenance carry over) already. We pulled off the runway. Opened the cockpit door and smoke and fumes came into the cockpit. We had another air carrier's pilot in the jump seat. I asked him to get out of the seat so I could see back to the oven and to help the flight attendant. The smoke and fumes continued and increased. We told her to pull the galley oven circuit breakers. It seemed to get worse. We turned off the galley power and then the jump seat pilot and the flight attendant both said it seemed to be subsiding some. We had already asked to return to the gate. At the gate I asked all passenger to exit the aircraft and take their bags with them. I called my maintenance coordinator and dispatcher and told them what happened. The coordinator stated he thought it was the oven unit itself. Contract maintenance at msp confirmed this also. We pulled the forward galley circuit breakers. We tried to air out the aircraft as best as possible, all doors open -- canopy to jetway open -- cockpit windows open, external conditioner air on. After about 30 mins we boarded the passenger and continued on to slc uneventfully. However, en route our flight attendant lead came up to the cockpit stating she and the other flight attendants were getting a sore throat and headache. Around the top of descent into slc, I went into the cabin and the electrical smell was still very strong. When we got to the gate in slc a male agent stated he could smell the electrical smoke. Block time for the flight was 2 hours 27 mins. Note: the electrical smoke and fire checklist was used but because we were on the ground and headed back to the gate was deemed not much help.

Title: AN ACR B737 FLC HAD THE FORWARD GALLEY EMIT ELECTRICAL SMOKE AND FUMES DURING TAXI OUT. AFTER MAINT DISABLED THE FORWARD GALLEY THE ACFT DEPARTED ONLY TO AGAIN EXPERIENCE ELECTRICALLY GENERATED FUMES ENRTE TO ITS DEST.

Narrative: B737-300 CLRED FOR TKOF RWY 12R AT MSP. FLT ATTENDANT CALLS COCKPIT ON INTERPHONE STATING SHE SMELLS ELECTRICAL SMOKE FROM FORWARD GALLEY OVEN. ONE SIDE WAS ON MCO (MAINT CARRY OVER) ALREADY. WE PULLED OFF THE RWY. OPENED THE COCKPIT DOOR AND SMOKE AND FUMES CAME INTO THE COCKPIT. WE HAD ANOTHER ACR'S PLT IN THE JUMP SEAT. I ASKED HIM TO GET OUT OF THE SEAT SO I COULD SEE BACK TO THE OVEN AND TO HELP THE FLT ATTENDANT. THE SMOKE AND FUMES CONTINUED AND INCREASED. WE TOLD HER TO PULL THE GALLEY OVEN CIRCUIT BREAKERS. IT SEEMED TO GET WORSE. WE TURNED OFF THE GALLEY PWR AND THEN THE JUMP SEAT PLT AND THE FLT ATTENDANT BOTH SAID IT SEEMED TO BE SUBSIDING SOME. WE HAD ALREADY ASKED TO RETURN TO THE GATE. AT THE GATE I ASKED ALL PAX TO EXIT THE ACFT AND TAKE THEIR BAGS WITH THEM. I CALLED MY MAINT COORDINATOR AND DISPATCHER AND TOLD THEM WHAT HAPPENED. THE COORDINATOR STATED HE THOUGHT IT WAS THE OVEN UNIT ITSELF. CONTRACT MAINT AT MSP CONFIRMED THIS ALSO. WE PULLED THE FORWARD GALLEY CIRCUIT BREAKERS. WE TRIED TO AIR OUT THE ACFT AS BEST AS POSSIBLE, ALL DOORS OPEN -- CANOPY TO JETWAY OPEN -- COCKPIT WINDOWS OPEN, EXTERNAL CONDITIONER AIR ON. AFTER ABOUT 30 MINS WE BOARDED THE PAX AND CONTINUED ON TO SLC UNEVENTFULLY. HOWEVER, ENRTE OUR FLT ATTENDANT LEAD CAME UP TO THE COCKPIT STATING SHE AND THE OTHER FLT ATTENDANTS WERE GETTING A SORE THROAT AND HEADACHE. AROUND THE TOP OF DSCNT INTO SLC, I WENT INTO THE CABIN AND THE ELECTRICAL SMELL WAS STILL VERY STRONG. WHEN WE GOT TO THE GATE IN SLC A MALE AGENT STATED HE COULD SMELL THE ELECTRICAL SMOKE. BLOCK TIME FOR THE FLT WAS 2 HRS 27 MINS. NOTE: THE ELECTRICAL SMOKE AND FIRE CHKLIST WAS USED BUT BECAUSE WE WERE ON THE GND AND HEADED BACK TO THE GATE WAS DEEMED NOT MUCH HELP.
