## Discrepancy

PASSENGERS COMPLAINED OF BURNING PLASTIC ODOR  WHICH MADE THEM NAUSEAS.  FOUND WING ANTI-ICE DUCT HEAT SHIELD OUT OF POSITION ALLOWING HEAT TO BE TRANSFERRED TO PLASTIC.  ADJUSTED AND PERFORMED SYS CHECK WITH NO DISCREPANCIES FOUND.  A SUBSEQUENT FLIGHT HAD A BURNING PLASTIC ODOR AND WHEN A FLIGHT CREW MEMBER STEPPED BACK TO INVESTIGATE A SLIGHT VISUAL AMOUNT OF SMOKE WAS SEEN IN AREA OF WING DE-ICE DUCT.   SUBSEQUENT INSPECTION REVEALED THAT THE INSULATION BLANKET HOOK AND LOOP STRIP HAD COME IN CONTACT WITH BARE METAL OF DE-ICE DUCT.  COVERED DE-ICE DUCT WITH HEAT SHIELD.  NO FURTHER FAULTS FOUND.
