If enacted, proposed legislation would change the landscape for “through-the-fence” operations at public use airports that receive Federal funding. Through-the-fence [TTF] operations occur when an airport sponsor enters into an agreement that permits access to airport taxiways, runways and facilities by aircraft based on land adjacent to, but not part of, airport property. TTF operations range from off-airport fixed base operators [FBOs] who provide aeronautical support and services, and often compete with on-airport FBOs to provide the same support and services, to residential TTF agreements that grant airport access from hangars and homes located on private property adjacent to an airport [also known as “fly-in communities” or “residential airparks”]. Historically, the Federal Aviation Administration [FAA] has “discouraged” TTF operations at Federally funded airports, especially by FBOs that would compete with on-airport FBOs. The FAA has approved some residential TTF agreements on a case-by-case basis.
