Overview
If you plan to build or modify a structure near a public airport, you need to get approval first. Submit a written notice at least 30 days in advance. This is a Pennsylvania law. You also need to fill out and submit PA Form AV-57 (PDF).
Please mail your completed form to:
PA Department of Transportation Bureau of Aviation
P.O. Box 3151 Harrisburg, PA 17105
The department will review your plans. They check for safety in the airspace and conflicts with flights.
