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. To file a Modification to an Antenna Structure Registration (ASR) the tower must be in a Constructed status. The FCC put this restriction in place to promote air safety by ensuring that a notice of construction can only be filed against an approved registration record. If the tower is constructed and you have not filed the required notification, you must do so prior to filing your modification.
Major Modifications will require Environmental Notification. The following changes are considered to be Major Modifications:
- Increasing Overall AGL Height by more than 20 feet (6.1 m), or by more than 10% of the total tower height
- Submitting an environmental assessment
- Changing the registered lighting to a less-preferred lighting style
- Ranking of FAA lighting styles, from most preferred to least preferred:
- No lights
- No red steady lights
- Red steady lights
The following changes are considered to be Minor Modifications and do not require Environmental Notice:
- Administrative Changes
- Updating the FAA Study Number
- Correcting Coordinates (The tower is not physically moving)
- Lowering the Overall AGL Height
- Changing registered lighting to a more preferred lighting style
