MI SB1304

Changes language in MCL 324.73301 from "shall" to "does not" to clarify that no cause of action arises for injuries to unpaying recreational users (fishing, hunting, hiking, snowmobiling, etc.) on another's land except for gross negligence or willful and wanton misconduct.

Adds immunity from liability for injuries resulting from aviation-related activities on private, noncommercial landing fields, except when caused by gross negligence or willful and wanton misconduct of the defendant.

Extends immunity to owners, lessees, or occupants of premises with private, noncommercial landing fields, eliminating their duty to maintain safe premises or warn users of hazardous conditions related to aviation activities.

Adds spectators of outdoor recreational activities to the list of persons protected under the immunity provisions, and expands protection to include Michigan trailways and public trails on any size land.

Defines key terms including "agricultural or farm products," "aviation-related activity" (including passenger and spectator participation), and "landing field" by reference to Michigan's Aeronautics Code.
