What’s the Process for Opening an Airport?

There are already a large number of airports in the USA, but new ones are still popping up each year. The Federal Aviation Administration has no procedures in place for building a private airport. However, there are general guidelines for standard designs which you can find on their website. Furthermore, you have to notify the FAA if you want to build a new private-use airport. And they need to comply with the Notice of Construction, Alteration, Activation, and Deactivation regulations. So, if you want to build your own airport, you need to notify the FAA by filling out this form and sending it to the nearest FAA airport’s office. In addition, you need to notify your state aviation agency and comply with local ordinances, laws, and state and federal regulations.

What’s the Oldest Airport Still Active in the USA?
