OH HB490

Amends Ohio's aviation laws (Chapter 4561 and 4563 of the Revised Code) to make comprehensive changes to regulations governing navigable airspace, structures, and airport operations.

Creates an Office of Aviation within the Department of Transportation's division of multi-modal planning and programs with an appointed administrator responsible for oversight of aviation matters.

Modifies permit requirements for structures that may obstruct navigable airspace, allowing the Department of Transportation to grant permits with waivers from obstruction standards based on aeronautic principles and safety considerations.

Establishes liability protections for the Department of Transportation and Office of Aviation from damages caused by obstructions when structures are installed without permits, non-compliant with permit terms, or installed under power siting board or airport zoning board authority.

Updates definitions and terminology throughout aviation regulations to align with federal standards (14 C.F.R. Part 77) and modernizes references from specific section numbers to chapter-based citations.
