Narrative

SHORT FINAL BTWN 800 FT AND 500 FT AGL FELT A 'THUD.' (LATER PAX CONFIRMED FLAMES OUT OF R ENG.) FO DETERMINED ENG FAIL R SIDE. FLAPS WERE RETRACTED TO 20 DEGS; AIRSPD WAS INCREASED; AN EMER WAS DECLARED; AND THE ACFT WAS LANDED STRAIGHT AHEAD. ONCE SAFELY ON GND; THE ENG WAS SECURED IN ACCORDANCE WITH EMER PROC. EMER GND VEHICLES DETERMINED IT WAS SAFE TO TAXI TO THE GATE. ALL PAX AND CREW DEPLANED NORMALLY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE CAPT STATED THAT HE WAS CAUGHT BY SURPRISE BY THIS ENG FAILURE. THE IDEA THAT THE ENG WOULD FAIL AT THIS POINT; WITH A LOW ENG PWR SETTING; AT 800 FT AGL; WITH THE WHOLE ARPT IN VIEW AHEAD OF HIM - - IT DIDN'T SEEM 'LOGICAL' FOR THE ENG TO FAIL AT THAT POINT. THE CAPT IS ALSO A SIMULATOR INSTRUCTOR SO THE RESPONSE WAS RAPID AND ALMOST PERFECT. HE CALLED FOR THE EMER PROC OF 20 DEGS OF FLAPS; INCREASED THE 'BUG' SPD 10 KTS AND TOLD THE FO TO DECLARE AN EMER. HE THEN FORGOT THAT; WHEN PLACING THE FLAPS FROM 30 DEGS TO 20 DEGS; THE NEW FLAP POS WOULD ARM THE GPWS FOR PROX TO GND WITH LESS THAN STANDARD LNDG FLAPS. HE SAID IT WAS A 'GOOD SIMULATOR EXERCISE' EVENT BECAUSE MOST CREWS ARE READY FOR AN ENG PROB AT TKOF PWR SETTINGS; NOT ON SHORT FINAL WITH REDUCED PWR. THE CREW HAD FLOWN THIS ACFT ALL DAY FOR A 7 HR PERIOD. A GOOD WAKE-UP CALL FOR THE COMPLACENT. THE POSTFLT INSPECTION SHOWED A FAILURE OF THE FRAME THAT SECURED THE STATOR BLADES; WITH ONE COMING OUT OF THE FRAME AND BEING INGESTED BY THE ENG. MAJOR ENG DAMAGE EXPECTED WHEN THEY FOUND METAL IN THE TAIL PIPE AREA. SUPPLEMENTAL INFO FROM ACN 410518: R ENG STALLED WITH A LOUD BANG THEN FLAMED OUT.
