MS HB697

Establishes the Mississippi Aviation Safety Act requiring owners of existing and newly constructed towers and structures between 50-200 feet in height to mark them consistently with FAA Advisory Circular AC 70/7460 IL beginning July 1, 2024.

Requires owners of newly constructed covered structures to disclose to the FAA and Mississippi Agricultural Aviation Association the structure's height, precise latitude/longitude coordinates, and obstruction marking or lighting type before construction completion.

Defines "covered towers" as meteorological evaluation towers, self-standing towers, real-time kinematic towers, or guy-wire supported towers that are 10 feet or less in diameter and located on or adjacent to rural agricultural land used for wind resource assessment.

Excludes from coverage street lights, advertising billboards, FCC-registered antenna structures determined by FAA to pose no hazard, and structures already mitigated for aviation safety hazards.

Directs appropriate entities (FAA and Mississippi Agricultural Aviation Association) to maintain current databases protecting proprietary information and restricting database use to aviation safety purposes only.
