B767 DEALS WITH CABIN SMOKE AND FUMES OVER MID ATLANTIC.

Narrative

LOCATION: 30W CENTRAL ATLANTIC OCEAN. IN THE DEAD CENTER OF THE ATLANTIC NEAR OUR SINGLE ETP WE NOTICED AN ELECTRICAL SMELL IN THE CABIN. QUICKLY ISOLATED IT TO SEATS 3A/B AND SHORTLY THEREAFTER SAW SMOKE FROM THE 3A/B CENTER CONSOLE. SMOKE FROM A KNOWN SOURCE. YET A SOURCE THAT HAS NO MENTION IN OUR MANUALS -- NO SWITCHES TO TURN OFF; NO CIRCUIT BREAKERS OUTSIDE OF THE E&E COMPARTMENT; AND NO PROC TO SOLVE. THE CLOSET PROC IS THE SMOKE FROM AN UNKNOWN SOURCE WHICH CUTS OFF BUSSES FROM UTILITY TO AC TO DC TO STANDBY. WE MUST ASSUME; WITH NO FURTHER INFO AT HAND; THAT THE UTILITY BUSSES WOULD CUT PWR TO THE ENTERTAINMENT SYS. VIA SATCOM LINK TO MAINT; WE WERE ABLE TO CUT ELECTRICAL PWR TO SEATS 3A/B BY USING A PHILLIPS SCREWDRIVER TO REMOVE A COVER UNDER THE SEATS AND DISCONNECT A CANON PLUG. PROB SOLVED. RESOURCES WE COULD HAVE USED BESIDES THE LUCK OF HAVING SATCOM WOULD HAVE BEEN ACCESSIBLE SWITCHES OR CIRCUIT BREAKERS TO DEACTIVATE ALL OR PARTS OF THE ENTERTAINMENT SYS -- A CLRLY MARKED COVER UNDER THE SEAT THAT COULD BE REMOVED WITHOUT TOOLS TO ACCESS THE CANON PLUG AND SOME INFO TO HELP US COPE WITH EVER MORE COMPLEX CABIN ELECTRONICS. WHILE THE BROAD AX SOLUTION OF CUTTING UTILITY PWR PROBABLY WOULD HAVE BEEN ENOUGH BY ITSELF; WE CAN DO BETTER THAN THAT WITH A LITTLE EFFORT; INFO; AND TRAINING.
