Sales tax: exemptions; purchase of certain aircraft and aviation equipment; exempt. Amends sec. 4x of 1933 PA 167 (MCL 205.54x).

SB 152 exempts sales of large aircraft (6,000+ pound takeoff weight) and qualifying parts/materials used for transporting cargo or passengers from Michigan's state sales tax. It directly affects domestic air carriers (businesses primarily transporting cargo or passengers) and aircraft sellers, provided the aircraft isn't based or registered in Michigan before/after the sale or maintenance. Key conditions include requiring the aircraft to leave Michigan within 15 days after qualifying transactions and excluding shop equipment, fuel, and smaller aircraft from the exemption. The bill modifies Michigan's General Sales Tax Act (MCL 205.54x) to create these specific tax exemptions.
