A VISUAL INSPECTION BY THE CREW AFTER LANDING REVEALED A LIFTED SECTION OF THE ICE SHIELD ON THE RT SIDE OF THE FUSELAGE. A MX ENGINEER WAS DISPATCHED TO INSPECT THE ACFT. THE INSPECTION REVEALED THAT A SECTION OF THE ICE SHIELD HAD LIFTED & CURLED BACK, RESULTING IN THE NOISE HEARD IN FLIGHT. THE LOOSENED SECTION WAS REMOVED & THE REMAINING SECTIONS INSPECTED FOR CONDITION & SECURITY WITH NO ADDITIONAL DEFECTS NOTED. THE ADJACENT FUSELAGE SKIN & SURROUNDING AREA WAS ALSO INSPECTED WITH NO DAMAGE PRESENT. THE ACFT WAS RELEASED & RETURNED TO BASE WHERE THE AFFECTED ICE SHIELD SECTION WAS REPLACED.
