When the commission, upon complaint or its own motion, has reason to believe that any aircraft is being operated without a certificate of public convenience and necessity as required by this act, or that this act is being violated, or that an air carrier is engaged in any other illegal activity, the commission shall investigate such activity and may, after consultation with the director, and after a hearing, make its order requiring the owner or operator of the aircraft to cease and desist from any such unlawful activity. The commission shall enforce compliance with such order under the powers vested in the commission by law, including, but not limited to, the provisions of chapter 7, title 61, Idaho Code.
