## Discrepancy

DFW TO JFK FLIGHT 6496 AT CRUISE THE A FLIGHT ATTENDANT INFORMED THE FLIGHT DECK THAT THERE WAS A STRONG BURNING SMELL IN THE FORWARD PART OF THE CABIN.  AT THE SAME MOMENT THE CREW NOTICE A BURNING SMELL AS WELL.  CREW DECLARED AN EMERGENCY AND DIVERTED TO IND.  THE SMELL SLOWLY STARTED TO DISSIPATE AFTER LANDING.  MAINTENANCE REPLACED THE NR 2 DUEL HEAT EXCHANGER AND CLEANED COFFEE RESIDUE FROM ACM.
