What was found
CORROSION WAS FOUND ON THE RT LEADING EDGE SKIN DURING A ROUTINE DE-ICE BOOT CHANGE. IT WAS FOUND ON THE OUTER PORTION LOWER SIDE OF THE SKIN. THE CORROSION WAS OF SUCH A DEPTH AFTER ITS REMOVAL THAT REPAIRS WERE REQUIRED. THE MOST LIKELY CAUSE IS POOR BOOT INSTALLATION LEAVING GAPS IN THE ADHERING SURFACES. THIS MAY HAVE ALLOWED THE AREAS TO FORM CONDENSATION BETWEEN THE BOOT AND SKIN AND OVER THE DE-ICE BOOTS 7+YEARS OF SERVICE.(K)
