(a) The Navigation Commission may impose any of the following sanctions, singly or in combination, when it finds that one or more of the conditions or violations set forth in section 31 apply to a pilot regulated by this act:

(b) The Navigation Commission may withdraw or reduce conditions of probation when it finds that the deficiencies which required the action have been remedied.

(c) The Navigation Commission may temporarily suspend a pilot's license under circumstances determined by the Navigation Commission to be an immediate and clear danger to public health and safety. The Navigation Commission shall issue an order to that effect without a hearing, but upon due notice to the licensee concerned at his or her last known address, which shall include a written statement of all allegations against the licensee. The Navigation Commission shall thereupon commence formal action to suspend, revoke or restrict the license of the person concerned as otherwise provided for in this act. All actions shall be taken promptly and without delay. Within thirty days following the issuance of an order temporarily suspending a license, the Navigation Commission shall conduct or cause to be conducted a preliminary hearing to determine that there is a prima facie case supporting the suspension. The licensee whose license has been temporarily suspended may be present at the preliminary hearing and may be represented by counsel, cross-examine witnesses, inspect physical evidence, call witnesses, offer evidence and testimony and make a record of the proceedings. If it is determined that there is not a prima facie case, the suspended license shall be immediately restored. The temporary suspension shall remain in effect until vacated by the Navigation Commission, but in no event longer than one hundred eighty days.
