## Discrepancy

AIRCRAFT WAS GROUNDED: ENG 2 STALL AT FL 350 WHEN WE WERE ASKED TO DESCEND AND SLOW TO MACH .75. ENG SPOILED DOWN TO BELOW 50% N1 AND THAT'S WHEN WE IMMEDIATELY HAD BUFFETING AND HAD A COMPRESSOR STALL ON THE NUMBER2 ENGINE. FOLLOWED QRH ENGINE RETURNED TO NORMAL PARAMETERS. EMERGENCY WAS DECLARED INTO ATL AND LANDED WITHOUT INCIDENT. MAINTENANCE REPLACED ENG2 PRSOV 4001HA2.
