Except as provided in subsection (b) of this section, the Secretary, Administrator of the Transportation Security Administration, or Administrator of the Federal Aviation Administration shall investigate the complaint if a reasonable ground appears to the Secretary, Administrator of the Transportation Security Administration, or Administrator of the Federal Aviation Administration for the investigation.

(B) any question that may arise under this part.

(3) The Secretary of Transportation, Administrator of the Transportation Security Administration, or Administrator of the Federal Aviation Administration may dismiss a complaint without a hearing when the Secretary, Administrator of the Transportation Security Administration, or Administrator of the Federal Aviation Administration is of the opinion that the complaint does not state facts that warrant an investigation or action.

(4) After notice and an opportunity for a hearing and subject to section 40105(b) of this title, the Secretary of Transportation, Administrator of the Transportation Security Administration, or Administrator of the Federal Aviation Administration shall issue an order to compel compliance with this part if the Secretary, Administrator of the Transportation Security Administration, or Administrator of the Federal Aviation Administration finds in an investigation under this subsection that a person is violating this part.

Section

In subsection (a)(1), the words "the Secretary of Transportation (or the Administrator of the Federal Aviation Administration with respect to aviation safety duties and powers designated to be carried out by the Administrator) about a person violating this part or a requirement prescribed under this part" are substituted for "the Secretary of Transportation or the Board, as to matters within their respective jurisdictions . . . with respect to anything done or omitted to be done by any person in contravention of any provisions of this chapter, or of any requirement established pursuant thereto" for clarity and because of the restatement. The words "Except as provided in subsection (b) of this section" are added because of the restatement of the source provisions in subsection (b) of this section. The words "If the person complained against shall not satisfy the complaint and" are omitted as surplus.
