This Aerospace Information Report (AIR) presents preferred practices for sealing and repairing integral fuel tanks, including rework of applied fuel tank seals. It addresses engineering designs for integral fuel tanks as they are currently found in practice; and this document discusses the most practical and conservative methods for producing a reliable, sealed system. Although this AIR presents practices for sealing of integral fuel tanks, the practices presented within this report are practices that are carried throughout sealing that include both pressure and environmental aircraft sealing.
