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 5453 amends the 1992 Dayton Aviation Heritage Preservation Act to add approximately 1 acre of land in Dayton, Ohio, to the Dayton Aviation Heritage National Historical Park. The adjustment, based on a February 2023 map, expands the park's existing boundary to include this specific parcel. The bill directly affects the park's physical boundaries but does not alter park operations, funding, or visitor access. This is a procedural boundary update with no new regulations or financial impacts.
