SEALING INTEGRAL FUEL TANKS
This Aerospace Information Report (AIR) presents preferred practices for sealing and repairing integral fuel tanks. It addresses several basic fuel tank designs as they are currently found in practice and discusses the most practical and conservative methods for producing a reliable, sealed system. Design preferences for optimum sealing are not within the scope of this document. Such discussions can be found in the Air Force sponsored handbook entitled Aircraft Integral Fuel Tank Design Handbook, AFWAL-TR-87-3078. The basic goal in sealing an integral fuel tank is to produce a system that is leak-free for the long term under the environmental and operational conditions expected.
