Narrative:

Inbound from ict the majority of the flight went normal. As we neared forestell VOR with the engines at flight idle, there was a loud bang from the rear of the aircraft, and then a continuous grinding sound. A scan of the cockpit instruments gave no indication of the problem. A flight attendant brought the news of the sound was emanating from the right side of the aircraft. At that time, in an effort to identify the engine, I increased power to the left engine with no sound out of the ordinary. I then increased power to the right engine. There was a noticeable increase in the grinding or engine roughness. Returned the engine to flight idle. I asked the first officer to review the QRH with me and called the L1 to the cockpit for instructions. I made a quick cabin announcement to the passenger as to what was transpiring. As we neared the airport, ATC advised that they were changing runway landing directions and this would cause some delay in landing. At that time, I declared an emergency so as to expedite our landing. We were given priority and cleared to land on runway 12R. The landing was uneventful and normal. After a quick inspection by the ground emergency personnel, we taxied to the gate where the mechanics were waiting to inspect the aircraft. The passenger deplaned with no complaints or requests for assistance. The mechanics discovered metal partials in the right engine oil filter. Their comments to us were that our actions saved the engine from self-destructing.

Title: MD80 CREW HAD ENG FAILURE ON ARR AT STL.

Narrative: INBOUND FROM ICT THE MAJORITY OF THE FLT WENT NORMAL. AS WE NEARED FORESTELL VOR WITH THE ENGS AT FLT IDLE, THERE WAS A LOUD BANG FROM THE REAR OF THE ACFT, AND THEN A CONTINUOUS GRINDING SOUND. A SCAN OF THE COCKPIT INSTS GAVE NO INDICATION OF THE PROB. A FLT ATTENDANT BROUGHT THE NEWS OF THE SOUND WAS EMANATING FROM THE R SIDE OF THE ACFT. AT THAT TIME, IN AN EFFORT TO IDENT THE ENG, I INCREASED PWR TO THE L ENG WITH NO SOUND OUT OF THE ORDINARY. I THEN INCREASED PWR TO THE R ENG. THERE WAS A NOTICEABLE INCREASE IN THE GRINDING OR ENG ROUGHNESS. RETURNED THE ENG TO FLT IDLE. I ASKED THE FO TO REVIEW THE QRH WITH ME AND CALLED THE L1 TO THE COCKPIT FOR INSTRUCTIONS. I MADE A QUICK CABIN ANNOUNCEMENT TO THE PAX AS TO WHAT WAS TRANSPIRING. AS WE NEARED THE ARPT, ATC ADVISED THAT THEY WERE CHANGING RWY LNDG DIRECTIONS AND THIS WOULD CAUSE SOME DELAY IN LNDG. AT THAT TIME, I DECLARED AN EMER SO AS TO EXPEDITE OUR LNDG. WE WERE GIVEN PRIORITY AND CLRED TO LAND ON RWY 12R. THE LNDG WAS UNEVENTFUL AND NORMAL. AFTER A QUICK INSPECTION BY THE GND EMER PERSONNEL, WE TAXIED TO THE GATE WHERE THE MECHS WERE WAITING TO INSPECT THE ACFT. THE PAX DEPLANED WITH NO COMPLAINTS OR REQUESTS FOR ASSISTANCE. THE MECHS DISCOVERED METAL PARTIALS IN THE R ENG OIL FILTER. THEIR COMMENTS TO US WERE THAT OUR ACTIONS SAVED THE ENG FROM SELF-DESTRUCTING.
