Antenna Structure Registration - Help
This article provides information on modifying a registration in the Antenna Structure Registration (ASR) system. You would modify a registration to change technical data about the structure. For example, increasing the height of the structure, changing the obstruction marking/lighting, correcting the coordinates or the FAA Study Number are all things that are filed on a modification application. A request to modify a registration may require Environmental Notice.
Changes to administrative information on your registration such as mailing address, phone number, or e-mail address are handled by filing an Administrative Update.
