14 CFR § 382.153 - What actions do CROs take on complaints?
When a complaint is made directly to a CRO for a carrier providing service using aircraft with 19 or more passenger seats, the CRO must promptly take dispositive action as follows:
(a) If the complaint is made to a CRO before the action or proposed action of carrier personnel has resulted in a violation of a provision of this part, the CRO must take, or direct other carrier personnel to take, whatever action is necessary to ensure compliance with this part.
(b) If an alleged violation of a provision of this part has already occurred, and the CRO agrees that a violation has occurred, the CRO must provide to the complainant a written statement setting forth a summary of the facts and what steps, if any, the carrier proposes to take in response to the violation.
(c) If the CRO determines that the carrier's action does not violate a provision of this part, the CRO must provide to the complainant a written statement including a summary of the facts and the reasons, under this part, for the determination.
(d) The statements required to be provided under this section must inform the complainant of his or her right to pursue DOT enforcement action under this part. The CRO must provide the statement in person to the complainant at the airport if possible; otherwise, it must be forwarded to the complainant within 30 calendar days of the complaint.
