A B757-200 LOW PRESSURE FUEL PUMP FAILED; CAUSING AN ENG FLAMEOUT. EMER DECLARED.

Narrative

WE WERE INSTRUCTED BY APCH CTL TO KEEP THE SPD AT OR ABOVE 240 KTS AS LONG AS POSSIBLE ON APCH. THE APCH WAS A VISUAL TO RWY 10 ABOUT 5-7 MI FROM THE RWY. WE WERE SWITCHED TO TWR A LITTLE LATE IN THE APCH AND WHEN I CONTACTED THE TWR; I ASKED FOR A VISUAL TO RWY 8. TWR RESPONDED WITH A LNDG CLRNC BUT IN THE MIDDLE OF THE CLRNC I NOTICED THE L ENG OIL PRESSURE LIGHT ON AND VERY LITTLE PRESSURE. I LATER HAD TO CLARIFY THE LNDG CLRNC WITH THE TWR BEFORE LNDG. AFTER NOTICING THE LOW OIL PRESSURE LIGHT; I SCANNED THE CRT SCREENS AND ALL THE ENG INSTS LOOKED THE SAME (EPR; RPM; AND EGT) AS THE R ENG; AND THE AMBER OIL PRESSURE ADVISORY LIGHT ON THE INST PANEL WAS OUT. THERE WERE ALSO NO EICAS MESSAGES AT ALL ON THE CRT'S. I POINTED OUT THE LOW PRESSURE LIGHT TO THE FO; THINKING THAT THERE MAY BE AN IMPENDING ENG PROB; AND WANTED HIM TO BE AWARE OF THIS. THE FO THEN ADVANCED THE L THROTTLE FROM IDLE SETTING AND THERE WAS NO RESPONSE FROM THE ENG AND ALL THE ENG PARAMETERS REMAINED THE SAME. THE FO THEN STATED THAT WE HAD LOST THE L ENG WHICH SURPRISED ME SINCE I WAS NOT LOOKING WHEN HE ADVANCED THE THROTTLE; AND THE GENERATOR AND ALL INDICATIONS OTHER THAN THE ONE PRESSURE LIGHT LOOKED NORMAL. AT THIS POINT WE WERE ON FINAL WITH FLAPS 5 DEGS SLOWING TOWARD APCH SPD BUT A LITTLE FAST DUE TO THE CTLR'S FAST APCH. WE LOWERED THE GEAR AND HAD THE SPD BRAKES OUT TO SLOW. I MENTIONED THAT WE NEEDED TO DO A FLAPS 20 DEG LNDG FOR SINGLE ENG; BUT I THINK HE ALREADY REMEMBERED THAT. AFTER CHKING ALL THE INSTS AGAIN AND DECIDING THAT WE HAD NO SEVERE DAMAGE OR FIRE; I CALLED THE TWR ON SHORT FINAL AND DECLARED AN EMER AS A PRECAUTION. THE LNDG WAS UNEVENTFUL AND AFTER CLRING THE RWY WE RECEIVED AN EICAS MESSAGE THAT THE LOW PRESSURE FUEL PUMP HAD FAILED. WE THEN CANCELLED THE EMER AND 1 FIRE TRUCK ESCORTED US TO THE GATE. SUMMARY: THE ONLY REAL SURPRISE TO US WAS THE TOTAL LACK OF INFO ON THE ENG FAILURE OTHER THAN THE LOW OIL LIGHT. THE ENG TURNED AT ALMOST NORMAL IDLE AND ALL THE SYS ON THE ENG STILL OPERATED NORMALLY. WE NEVER LOOKED AT THE FUEL FLOW UNTIL AFTER EXITING THE RWY OR WE WOULD HAVE REALIZED THE PROB SOONER. THE EMER CHKLISTS WERE NOT RUN SINCE WE HAD VIRTUALLY NO TIME TO DO THEM. THE ONLY PA THAT I MADE WAS AFTER LNDG TO ADVISE BOTH THE FLT ATTENDANTS AND THE PAX WHY THE FIRE TRUCKS WERE AROUND THE ACFT. THE FIRE TRUCKS RESPONDED INCREDIBLY FAST SINCE WE DECLARED THE EMER ON VERY SHORT FINAL AND THEY CAUGHT US AS WE TURNED OFF THE RWY.
