## Discrepancy

A STRONG ODOR WAS REPORTED IN THE MAIN CABIN BY FLIGHT ATTENDANTS JUST AFTER TAKEOFF.  THE RT PACK WAS TURNED OFF AND ODOR WENT AWAY.  THE ODOR WAS DESCRIBED AS HAVING THE SMELL OF BURNING MARSHMALLOWS.  MAINTENANCE FOUND A COALESCER BAG CONTAMINATED.  THE BAG WAS REMOVED AND REPLACED.  THE RT PACK WAS RUN FULL HOT FOR SEVERAL MINUTES WITH NO ODOR NOTED.  NO OTHER DISCREPANCIES WERE NOTED.
