The United States has the world's most extensive airport system, which is essential to national transportation and the U.S. economy. According to the 1999 Bureau of Transportation Statistics, there were 5,324 public-use airports and 13,774 private-use airports in the United States. A typical airport infrastructure is complex, and components that might be subject to corrosion include the natural gas distribution system, jet fuel system storage and distribution system, deicing storage and distribution system, vehicle fueling systems, natural gas feeders, dry fire lines, parking garages, and runway lighting. Generally, each of these systems is owned or operated by different organizations or companies; therefore, the impact of corrosion on an airport as a whole is not known or documented. However, the airports do not have any specific corrosion-related problems, which are not described elsewhere in this report.

A typical airport infrastructure is relatively complex, and components that might be subject to corrosion include the natural gas distribution system, jet fuel storage and distribution system, deicing storage and distribution system, water distribution system, vehicle fueling systems, natural gas feeders, dry fire lines, parking garages, and runway lighting. Generally, each of these facilities is owned or operated by different organizations and companies, and the impact of corrosion on an airport as a whole is not known or documented; however, the airports do not have any specific corrosion-related problems, which have not been described in other sectors, such as corrosion in water distribution lines, gas distribution lines, corrosion of concrete structures, and aboveground and underground storage tanks.
