## Discrepancy

THE CREW REPORTED LOUD CLUNKING SOUNDS WHILE IN CLIMB, CRUISE AND DESCENT.  THE CABIN TEMPERATURE WAS REPORTED AS BEING HIGH AND A BURNING PAINT SMELL WAS NOTED WHEN THE WING ANTI-ICE HEAT WAS OPERATING.  MAINTENANCE REPLACED THE FLOW INCREASING VALVE.  SATISFACTORY OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RETURNED TO SERVICE.
