## Discrepancy

SHIP 9519 -ATB/FUME/DE- DURING CLIMB OUT AT ABOUT 10K FEET, THE FLIGHT CREW DECLARED AN EMERGENCY WITH ATC AND RETURNED TO MEM DUE TO UNKNOWN ODOR THROUGHOUT THE CABIN. CORRECTIVE ACTION: MAINTENANCE DISCOVERED THAT THE BUFFER AIR VALVE ON THE #2 ENGINE WAS VERY STIFF IN IT'S OPERATION AND REPLACED IT. THE ODOR WAS REMOVED AND THE AIRCRAFT RETURNED TO SERVICE.
