Montana Title 67. Aeronautics § 67-3-202. Penalty for registration violations

(1) When an aircraft required to be registered under the provisions of subsections (2) and (4) through (6) of 67-3-201 is not registered on or before March 1 of the current calendar year, a penalty of five times the annual registration fee provided in 67-3-206 must be added to the registration fee and collected. Registration of an aircraft in the name of the applicant for the year immediately preceding the year for which application for registration is made shall be prima facie evidence that the aircraft has been based in this state during the year for which application for registration is made.

(2) A person who owns or causes or authorizes an aircraft to be operated or who operates an aircraft required to be registered in the state without having displayed upon such aircraft a certificate of registration issued by the department for that aircraft commits a misdemeanor.
