Narrative:

On descent into bna with the captain as PF and the first officer as PNF, at 15000 ft MSL and reducing power, left engine compressor stall noted. EPR 1.3 to 1.4, 310 KIAS and 65 DME east of bna. Vibration quickly stopped and engine instruments all indicated normal. At 8500 ft MSL 250 KIAS, captain was increasing power when vibration started again and continued. EPR 1.1 to 1.2. As vibration continued left engine was noticed to be winding down and N1 was 30 percent and decreasing. Captain decided to shut down the left engine. After declaring an emergency, we accomplished the engine failure emergency checklist and single engine approach abnormal procedure was reviewed. A 25 degree flap landing was accomplished with no complications.

Title: MLG HAS COMPRESSOR STALL, THEN DECREASE IN ENG PWR. ENG SHUT DOWN.

Narrative: ON DSCNT INTO BNA WITH THE CAPT AS PF AND THE FO AS PNF, AT 15000 FT MSL AND REDUCING PWR, L ENG COMPRESSOR STALL NOTED. EPR 1.3 TO 1.4, 310 KIAS AND 65 DME E OF BNA. VIBRATION QUICKLY STOPPED AND ENG INSTRUMENTS ALL INDICATED NORMAL. AT 8500 FT MSL 250 KIAS, CAPT WAS INCREASING PWR WHEN VIBRATION STARTED AGAIN AND CONTINUED. EPR 1.1 TO 1.2. AS VIBRATION CONTINUED L ENG WAS NOTICED TO BE WINDING DOWN AND N1 WAS 30 PERCENT AND DECREASING. CAPT DECIDED TO SHUT DOWN THE L ENG. AFTER DECLARING AN EMER, WE ACCOMPLISHED THE ENG FAILURE EMER CHKLIST AND SINGLE ENG APCH ABNORMAL PROC WAS REVIEWED. A 25 DEG FLAP LNDG WAS ACCOMPLISHED WITH NO COMPLICATIONS.
