B767 FLT CREW REPORTS ENGINE FLAMEOUT ON NAT TRACK SHORTLY AFTER CENTER TANK FUEL TANK FUEL PUMPS ARE TURNED OFF; WITH DIVERSION TO ENROUTE ALTERNATE.

Narrative

WE WERE XING THE NORTH ATLANTIC ON THE NORTH ATLANTIC TRACK SYS (NAT). AS WE WERE APCHING N60 W040; THE FO NOTICED THE CTR TANK FUEL WAS BELOW 1000 LBS AND REACHED UP AND TURNED OFF THE CTR TANK FUEL BOOST PUMPS; AS PER OPERATING PROCS. ABOUT 30 SECONDS LATER; THE R AFT FUEL BOOST PUMP LOW 'PRESS' LIGHT ILLUMINATED. I POINTED THIS OUT TO THE FO AND WAS ABOUT TO ASK HIM TO TURN AROUND AND CHK THE BOOST PUMP CIRCUIT BREAKER TO SEE IF IT HAD POPPED. BEFORE I COULD DO THAT; THE ENG FLAMED OUT. THERE WAS NO COMPRESSOR STALL; NO SURGE; NO RUMBLE; NOTHING AT ALL. IT WAS AS IF THE FUEL TO THE ENG HAD BEEN CUT OFF. WE IMMEDIATELY BEGAN CLRING THE TRACK AND PERFORMING THE 'DRIFT-DOWN' PROCS AND ALSO PERFORMING THE 'ENG FAILURE' CHKLIST. AS WE GOT BELOW THE ORGANIZED TRACK SYS; WE PROCEEDED DIRECTLY TO ZZZ WHICH WAS OUR CURRENT ETP (EQUAL TIME POINT) ALTERNATE. WE STAYED CLR OF CLOUDS THE ENTIRE TIME SINCE I DIDN'T WANT TO DEAL WITH ANY ASYMMETRICAL ICING CONDITIONS ON THE WINGS AND ENG COWLINGS. WE BROADCAST OUR INTENTIONS ON GUARD AND GOT ANOTHER ACFT TO RELAY OUR INTENTIONS TO COMPANY AND ZZZZ RADIO WHILE WE HAD OUR HANDS FULL. WE EVENTUALLY CONTACTED BOTH COMPANY AND ZZZZ RADIO AND GOT CLRNC TO PROCEED TO ZZZ AND THEN GOT IN VHF CONTACT AND RADAR CONTACT WITH ZZZ CTL AND MADE AN UNEVENTFUL SINGLE-ENG APCH AND LNDG. I HAVE TALKED WITH COMPANY MAINT AND THEY FOUND SEVERAL THINGS HAD HAPPENED IN THE EEC AND FUEL CTL UNITS ON THE ENG; BUT NOTHING THAT SHOULD HAVE CAUSED A SHUTDOWN; NOT EVEN IN COMBINATION. THE ENG SHOULD HAVE KEPT RUNNING IN AN ALTERNATE MODE OF CTL. MAINT CHANGED OUT SEVERAL COMPONENTS ON THE ENG; AND THE ACFT FLEW BACK 2 DAYS LATER. CREW COORD AND CRM WERE EXCELLENT IN MY OPINION. ATC HANDLING WAS ALSO EXCELLENT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR WAS UNABLE TO ADD ANY ADDITIONAL INFORMATION ABOUT THIS INCIDENT OTHER THAN TO RPT THAT THE SUSPECT FUEL CTL COMPONENTS WERE REPLACED SO THAT THEY COULD BE THOROUGHLY EXAMINED. CALLBACK CONVERSATION WITH RPTR ACN 744833 REVEALED THE FOLLOWING INFO: NO ATTEMPT WAS MADE TO RESTART THE ENG ALTHOUGH NO MECHANICAL DAMAGE APPEARED TO EXIST AND FUEL WAS FLOWING PRIOR TO PERFORMING THE ENG FAILURE CHKLIST.
