## Discrepancy

DURING TAKEOFF, STRONG SMELL OF SMOKE WAS NOTICED IN CABIN.  FLIGHT CREW DECLARED A YELLOW EMERGENCY AND RETURNED TO DEPARTING STATION.  FLIGHT LANDED OVERWEIGHT BUT EVERYTHING ELSE WAS NORMAL.  MAINTENANCE INSPECTED DUCTS, GALLEYS, AND LIGHTS; NO FAULT FOUND.  MAINTENANCE FOUND THE NR 1 PACK OVERHEATING.  REPLACED THE ACM WHICH TESTED AND CHECKED GOOD.  AIRCRAFT RETURNED TO SERVICE.
