To amend the Dayton Aviation Heritage Preservation Act of 1992 to adjust the boundary of the Dayton Aviation Heritage National Historical Park, and for other purposes.

HR 4747 amends the Dayton Aviation Heritage Preservation Act of 1992 to expand the boundary of the Dayton Aviation Heritage National Historical Park by adding approximately 1 acre of land in Dayton, Ohio. The bill specifies this adjustment using a map dated February 2023, which details the exact parcel to be included. This change directly affects the park's physical boundaries but does not alter the park's management, purpose, or existing protections. The amendment is procedural, focusing solely on updating the park's geographic scope.
