Reauthorization Program Guidance Letters (R-PGLs)

The FAA Reauthorization Act of 2018 (P.L. 115-254), hereafter referred to as “the 2018 Act,” included numerous changes to statutes and other authorizing Acts governing the operations and administration of multiple programs under the Office of Airports (ARP or Airports). R-PGLs communicate the provisions in the 2018 Act that impact Airports' programs.

Note: Provisions requiring further implementation may not be available immediately. The Office of Airports encourages users to sign up for notifications to receive announcements when the content on this page is updated. Additional guidance on other sections in the 2018 Act may be issued by the Office of Airport Safety and Standards and the Office of Airport Compliance and Management Analysis, as applicable.
