In any case in which the executive director of the Connecticut Airport Authority refuses to issue a certificate of approval of, or license or renewal of license for, an airport, restricted landing area, heliport or other air navigation facility, or in any case in which the executive director issues any order requiring certain things to be done or revoking any license, the executive director shall set forth the reasons therefor and shall state the requirements to be met before such approval shall be given, license granted or order modified or changed. Any order made by the executive director pursuant to the provisions of this chapter shall be served upon the interested persons by registered or certified mail or in person. To carry out the provisions of this chapter, the executive director and any official or employee of the authority and any state or municipal officer charged with the duty of enforcing this chapter may inspect and examine at reasonable hours any premises and the buildings and other structures thereon where airports, restricted landing areas, heliports, air schools, flying clubs or other air navigation facilities or aeronautical activities are operated or carried on. No provision of this section shall prohibit the executive director from suspending or revoking the right of any person to pilot, or the right to any operation of any aircraft within this state, for any cause that is deemed sufficient, with or without a hearing. No appeal taken from the action of the executive director shall act as a stay of suspension or revocation except with the executive director’s consent and under such conditions as the executive director may prescribe. No service of process shall be necessary in connection with any of the prescribed activities of the executive director. The term of any suspension or revocation shall commence upon notice thereof by the executive director.
