DC10 CREW HAD ENG FAILURE IN ZME CLASS A AIRSPACE.

Narrative

#2 ENG FAILURE OCCURRED WHILE IN STABLE CRUISE FLT AT FL350 WITH ALL SYS IN A NORMAL CONFIGN. THE FAILURE OCCURRED APPROX 2 HRS 15 MINS INTO THE FLT FROM BOS TO MEM. INITIAL INDICATION OF A MALFUNCTION WAS THE SLOW STEADY INTERMITTENT ILLUMINATION OF THE R AFT FUEL BOOST PUMP LOW PRESSURE LIGHT. MY INITIAL THOUGHT WAS THE R AFT FUEL BOOST PUMP WAS FAILING. I NOTIFIED THE CAPT OF THE PROB. WITHIN A FEW SECONDS OF NOTIFYING THE CAPT; THERE WAS A RAPID LOSS OF FUEL PRESSURE TO THE #2 ENG WHICH WAS BEING FED DIRECTLY FROM THE #2 FUEL TANK WHERE THE R AFT BOOST PUMP IS LOCATED. THE #2 FUEL QUANTITY INDICATOR READ 10800 LBS. THE CAPT QUICKLY CALLED FOR ALL FUEL XFEED VALVES TO BE OPENED. I OPENED ALL XFEED VALVES AND TURNED ON ALL FUEL BOOST PUMPS. THE #2 ENG FAILED AND NO RESTART WAS ATTEMPTED. AN INFLT EMER WAS DECLARED WITH ZME. RED TAB (EMER) CHKLIST APPROPRIATE TO THE SIT WAS COMPLETED DURING THE DSCNT TO MEM. AN UNEVENTFUL LNDG ON MEM RWY 36R WAS ACCOMPLISHED. TAXI TO THE GATE AND SHUTDOWN WERE ALSO UNEVENTFUL.
