Aeronautics: other; aircraft registration fees; modify. Amends sec. 77 of 1945 PA 327 (MCL 259.77).

SB 563 modifies Michigan's aircraft registration fee structure by changing how fees are calculated. It specifies that fees must be paid at "1 cent per pound of either maximum gross weight or maximum takeoff weight, whichever is greater," replacing prior ambiguous language. This directly affects all aircraft owners in Michigan required to register their planes under state law. The change clarifies the fee mechanism while maintaining that registration fees cover all property taxes on aircraft and set clear annual payment deadlines.
