(a) The executive director may approve airports, heliports, restricted landing areas, and other air navigation facilities. Any municipality or person acquiring property for the purpose of constructing or establishing an airport, heliport or restricted landing area shall, prior to such acquisition, apply to the executive director for a certificate of approval of the site selected and the general purpose or purposes for which the property is to be acquired, to insure that the property and its use shall conform to minimum standards of safety and shall serve the public interest. Any proposed airport, heliport, restricted landing area or other air navigation facility at which more than thirty-six landings and takeoffs are expected to be made by aircraft in any year shall be approved by the executive director before it shall be licensed to be used or operated. The executive director shall make no charge for approval certificates of proposed property acquisition for airport, heliport or restricted landing area purposes.

(b) The executive director may license airports, heliports, restricted landing areas and other air navigation facilities and renew such licenses. When a certificate of approval of an airport, heliport or restricted landing area has been issued by the executive director, he or she may grant a license for operation and use. On and after July 1, 1995, the executive director shall charge a fee of one hundred fifty dollars for each license or renewal thereof. Each such license shall be effective for a period of three years from the date of issuance. Each licensee shall certify, on a form provided by the executive director, that the licensed facility shall comply with all applicable federal, state and local laws and regulations during the license period. Municipalities shall be exempt from the payment of any license fee in connection with airports owned or operated by such municipalities.

(c) No municipality or officer or employee thereof and no person shall operate an airport, heliport, restricted landing area or other air navigation facility for which approval has not been granted, and a license has not been issued, by the executive director. The provisions of this section shall not apply to any airport, heliport, restricted landing area or other air navigation facility owned by the federal government within this state.

(d) Any heliport in operation prior to October 1, 1985, shall be deemed licensed for operation and use and the executive director shall issue an original license for any such heliport upon the written request of the person who controls and operates such heliport. Such heliports shall be subject to the provisions of this chapter concerning the renewal or revocation of licenses, inspection and review of air navigation facilities and any other provision of this chapter except those concerning the initial approval or licensing of such facilities. Such heliports shall be subject to any rule or procedure adopted by the authority in accordance with the provisions of this chapter except those concerning the initial approval or licensing of any air navigation facility.
