B757 FLT CREW HAS R ENG FAILURE AFTER TKOF; DECLARES EMER AND RETURNS FOR LNDING.

Narrative

OUR TKOF WAS PLANNED WITH FLAPS 15 DEGS AND MAX THRUST. WE WERE NEAR MAX TKOF WT AND THE RWY CONDITION WAS WET. THE PWR WAS SET AT 1.77 EPR AND THE TKOF WAS NORMAL UNTIL AT 1500 FT AFL THE CAPT CALLED FOR 'VNAV; FLAPS 5 DEGS; CLB PWR' AT WHICH TIME I SELECTED THE VNAV AND MOVED THE FLAP LEVER TO 5 DEGS. AS I PLACED MY L HAND ON THE THROTTLES TO ENSURE A SMOOTH TRANSITION FROM TKOF TO CLB PWR THE AIRPLANE YAWED AGGRESSIVELY TO THE R AND BEGAN A TURN TO THE R AND A LOUD BANG WAS HEARD FROM THE R SIDE OF THE AIRPLANE. I LOOKED AT THE ENG INSTS AND NOTICED THE R EPR; RPM; AND EGT DECREASING. THE RELIEF PLT IMMEDIATELY CALLED OUT 'R ENG.' THE CAPT; WHO WAS FLYING THE AIRPLANE; ADDED THRUST TO THE L ENG; ADDED RUDDER; AND BEGAN A LEVEL L TURN AT APPROX 1500 FT. OUR AIRSPD WAS AROUND 180 KTS. I DECLARED AN EMER WITH TWR. I TOLD THE CAPT THAT HE WAS FLYING THE AIRPLANE AND THAT HE 'HAD ATC' COMS WHILE I RAN THE ENG FIRE/FAILURE CHKLIST. I COMPLETED THE CHKLIST AND SHUT DOWN THE AFFECTED ENG. THE RELIEF PLT WAS VERY HELPFUL DURING THIS TIME COORDINATING WITH THE CAPT AND ATC AND THE FLT ATTENDANTS. ON DOWNWIND; I RETURNED TO HELPING THE CAPT FLY THE AIRPLANE. WE WERE IMC IN THE CLOUDS AT APPROX 1200 FT AFL. TWR GAVE US A BASE LEG TURN AT 5 MI OUT. WE BEGAN TO CONFIGURE THE AIRPLANE FOR LNDG WITH LNDG GEAR AND FLAPS 20 DEGS. AS WE DSNDED THROUGH 900 FT AFL; WE VISUALLY ACQUIRED THE RWY AND LANDED AT ZZZ. THE TOUCHDOWN WAS SMOOTH AND WE CAME TO A STOP ABOUT 6500 FT DOWN THE RWY. A PA WAS MADE TELLING 'EVERYONE TO REMAIN IN THEIR SEATS WITH THEIR SEATBELTS FASTENED.' CFR WAS STANDING BY ON GND FREQ AND TOLD US THEY SAW NO FIRE OR SMOKE OR ANY APPARENT DAMAGE TO THE EXTERIOR OF THE AIRPLANE. WE DECIDED TO TAXI TO THE OUTSIDE GATE AREA IN CASE OUR HOT BRAKES BECAME AN ISSUE. AN RF FOLLOWED US TO THE GATE AND WE DEPLANED NORMALLY.
