1. Draft and recommend necessary legislation to advance the interests of the state in aerospace and aeronautics;

2. Represent the state in aeronautical matters before federal agencies and other state agencies; and

3. Participate as party plaintiff or defendant or as intervener on behalf of the state or any municipality or citizen thereof in any proceeding which involves the interest of the state in aerospace or aeronautics.

G. 1. The Department may, insofar as is reasonably possible, make available its engineering and other technical services to any municipality or person desiring them in connection with the planning, acquisition, construction, improvement, maintenance, or operation of airports or navigation facilities.

2. The Department may render financial assistance by grant or loan or both to any municipality or municipalities acting jointly in the planning, acquisition, construction, improvement, maintenance, or operation of an airport owned or controlled, or to be owned or controlled, by such municipality or municipalities, out of appropriations or other monies made available by the Legislature for such purposes. Such financial assistance may be furnished in connection with federal or other financial aid for the same purposes.

3. The Department shall be designated as the agent of this state or political subdivision of this state for the purpose of applying for, receiving, administering and disbursing federal funds and other public monies for the benefit of general aviation airports, except reliever airports, as may be available under applicable federal law or other laws. If requested by a political subdivision, the Department may act as its or their agent in contracting for and supervising such planning, acquisition, construction, improvement, maintenance, or operation; and all political subdivisions are authorized to designate the Department as their agent for the foregoing purposes. The Department, as principal on behalf of the state, may enter into any contracts with the United States or with any person, which may be required in connection with a grant or loan of federal monies for municipal airport or air navigation facility purposes. All federal monies accepted under this section shall be accepted and transferred or expended by the Department upon such terms and conditions as are prescribed by the United States. All monies received by the Department pursuant to this section shall be deposited in the Oklahoma Department of Aerospace and Aeronautics Revolving Fund in the State Treasury and shall be paid out by the Department in accordance with the terms and conditions of any agreement entered into under the provisions of this section.

H. 1. The Department is authorized on behalf of and in the name of the state, out of appropriations and other monies made available for such purposes, to plan, zone, establish, construct, enlarge, improve, maintain, equip, operate, regulate, protect, and police airports and air navigation facilities, either within or without the state, including the construction, installation, equipping, maintenance, and operation at such airports of buildings and other facilities for the servicing of aircraft or for the comfort and accommodation of air travelers. However, the regulatory authority shall not extend to any airman employed by, nor to any aeronautics facility or aircraft under the exclusive possession, operation, or control of, a person holding a certificate of public convenience and necessity issued by any agency of the United States to operate as a common carrier by air of persons and/or property in interstate commerce. For such purposes the Department may, by purchase, gift, devise, or lease, acquire property, real or personal, or any interest therein including easements in aeronautical hazards or land outside the boundaries of an airport or airport site, as are necessary to permit safe and efficient operation of the state airports or to permit the removal, elimination, obstruction-marking or obstruction-lighting of airport hazards, or to prevent the establishment of airport hazards. In like manner the Department may acquire existing airports and air navigation facilities. However, the Department shall not acquire or take over any airport or air navigation facility owned or controlled by a municipality of this or any other state without the consent of such municipality. The Department may, by sale, lease, or otherwise, dispose of any such property, airport, air navigation facility, or portion thereof or interest therein. The disposal, by sale, lease, or otherwise, shall be in accordance with the laws of this state governing the disposition of other property of the state, except that, in the case of disposals to any municipality or state government or the United States for aeronautical purposes incident thereto, the sale, lease, or other disposal may be effected in such manner and upon such terms as the Department may deem in the best interest of the state.

2. All airports owned by the state shall be within the primary jurisdiction of the Oklahoma Department of Aerospace and Aeronautics for purposes of design, development, and operation; provided, that airports owned and operated by the Oklahoma Space Industry Development Authority shall be exempt from such provisions, and during the time of a national emergency, the Air National Guard shall be exempt from such provisions, and provided further, that any airport owned by the state may be leased by the Department to a public or private agency, as it may deem fit.

3. Nothing contained in the Oklahoma Department of Aerospace and Aeronautics Act¹ shall be construed to limit any right, power, or authority of the state or a municipality to regulate airport hazards by zoning.

4. The Department may exercise any powers granted by this section jointly with any municipalities or with the United States.

6. In accepting federal monies under this section, the Department shall have the same authority to enter into contracts on behalf of the state as is granted to the Department under paragraph 3 of subsection G of this section with respect to federal monies accepted on behalf of municipalities. All monies received by the Department pursuant to this section shall be deposited in the Oklahoma Department of Aerospace and Aeronautics Revolving Fund in the State Treasury and shall be paid out of the Department Fund in accordance with the terms and conditions of any agreement entered into under the provisions of this section.

7. The Department shall grant no exclusive right for the use of any airport or air navigation facility under its jurisdiction. This shall not be construed to prevent the making of contracts, leases, and other arrangements pursuant to paragraph 5 of this subsection.

J. 1. The Commission, the Director, or any officer or employee of the Department designated by it shall have the power to hold investigations, inquiries, and hearings concerning matters covered by the provisions of the Oklahoma Department of Aerospace and Aeronautics Act and the rules, regulations, and orders of the Department. Hearings shall be open to the public and shall be held upon such call or notice as the Commission shall deem advisable. Each member of the Commission, the Director, and every officer or employee of the Department designated by it to hold any inquiry, investigation, or hearing shall have the power to administer oaths and affirmations, certify to all official acts, issue subpoenas, and order the attendance and testimony of witnesses and the production of papers, books, and documents. In case of the failure of any person to comply with any subpoena or order issued under the authority of this subsection, or on the refusal of any witness to testify to any matters regarding which he may be lawfully interrogated, it shall be the duty of the district court of any county or of the judge thereof, on application of the Department or its authorized representative, to compel obedience by proceedings for contempt, as in the case of disobedience of the requirements of a subpoena issued from such court or a refusal to testify therein.

2. In order to facilitate the making of investigations by the Department in the interest of public safety and promotion of aeronautics the public interest requires, and it is therefore provided, that the reports of investigations or hearings, or any part thereof, shall not be admitted in evidence or used for any purpose in any suit, action, or proceeding growing out of any matter referred to in the investigation, hearing, or report thereof, except in case of any suit, action, or proceeding, civil or criminal, instituted by or in behalf of the Department or in the name of the state under the provisions of the Oklahoma Department of Aerospace and Aeronautics Act or other laws of the state relating to aeronautics; nor shall any member of the Commission, or the Director, or any officer or employee of the Department be required to testify to any facts ascertained in, or information gained by reason of, such person's official capacity, or be required to testify as an expert witness in any suit, action, or proceeding involving any aircraft. Subject to the foregoing provisions, the Department may in its discretion make available to appropriate federal, state and municipal agencies information and material developed in the course of its investigations and hearings.

K. 1. The Department is authorized to confer with or to hold joint hearings with any agency of the United States in connection with any matter arising under the Oklahoma Department of Aerospace and Aeronautics Act or relating to the sound development of aerospace and aeronautics.

2. The Department is authorized to avail itself of the cooperation, services, records, and facilities of the agencies of the United States as fully as may be practicable in the administration and enforcement of the Oklahoma Department of Aerospace and Aeronautics Act. The Department shall furnish to the agencies of the United States its cooperation, services, records, and facilities, insofar as may be practicable.

3. The Department shall report to the appropriate agency of the United States all accidents in aeronautics in this state of which it is informed and shall, insofar as is practicable, preserve, protect, and prevent the removal of the component parts of any aircraft involved in an accident being investigated by it until the federal agency institutes an investigation.
