What was found
THE LT FORWARD SEAT TRACK WAS CORRODED THROUGH THE SIDE OF THE TRACK AND THE TRACK AND THE FLANGE THAT SUPPORTS THE FLOORBOARD. CORROSION WAS PARTICULARLY EVIDENT AT FUSELAGE STA 158.5 - 170.5. THE LOCATION OF THE CORROSION, JUST INSIDE THE AIRSTAIR DOOR, SUGGESTS THAT IT MAY BE THE RESULT OF MOISTURE AND ICE-MELT PRODUCTS (SALT) CARRIED INTO THE CABIN ON PASSENGERS FOOTWEAR. (K)
