Title 49 - Transportation last revised: May 30, 2024
§ 831.1 - Applicability of this subpart.

(a) Except as provided in Subpart E of this part regarding marine casualties, and unless specified by the National Transportation Safety Board (NTSB), the provisions of this subpart apply to all NTSB investigations conducted under its statutory authority.

(b) Consistent with its statutory authority, the NTSB conducts investigations of transportation accidents that include, but are not limited to: accidents, collisions, crashes, derailments, explosions, incidents, mishaps, ruptures, or other similar accidents. Use of the term “accident” throughout this part includes all such occurrences.

(c) Throughout this part, the term “IIC” means the NTSB investigator-in-charge.

§ 831.2 - Responsibility of the NTSB.

The NTSB is required to investigate—

(a) Aviation accidents as described in subpart B of this part;

(b) Highway accidents as described in subpart C of this part;

(c) Railroad, pipeline, and hazardous materials accidents as described in subpart D of this part; and

(d) Any accident that occurs in connection with the transportation of people or property that, in the judgment of the NTSB, is catastrophic, involves problems of a recurring nature or would otherwise carry out the intent of its authorizing statutes. This authority includes selected events involving the transportation of hazardous materials, including their release.

§ 831.3 - Authority of Directors.

Subject to the provisions of § 831.2 of this part and part 800 of this chapter, the Directors of the Office of Aviation Safety, Office of Highway Safety, or Office of Railroad, Pipeline and Hazardous Materials Investigations, may order an investigation into any transportation accident.

§ 831.4 - Nature of investigation.

(a) General. The NTSB conducts investigations, or has them conducted, to determine the facts, conditions, and circumstances relating to an accident. The NTSB uses these results to determine one or more probable causes of an accident, and to issue safety recommendations to prevent or mitigate the effects of a similar accident. The NTSB is required to report on the facts and circumstances of accidents it investigates. The NTSB begins an investigation by monitoring the situation and assessing available facts to determine the appropriate investigative response. Following an initial assessment, the NTSB notifies persons and organizations it anticipates will be affected as to the extent of its expected investigative response.

(b) NTSB products. An investigation may result in a report or brief of the NTSB's conclusions or other products designed to improve transportation safety. Other products may include factual records, safety recommendations, and other safety information.

(c) NTSB investigations are fact-finding proceedings with no adverse parties. The investigative proceedings are not subject to the Administrative Procedure Act (5 U.S.C. 551 et seq.), and are not conducted for the purpose of determining the rights, liabilities, or blame of any person or entity, as they are not adjudicatory proceedings.

§ 831.5 - Priority of NTSB investigations.

(a) Relationships with other agencies. (1) Except as provided in 49 U.S.C. 1131(a)(2)(B) and (C) regarding suspected criminal actions, an investigation conducted under the authority of the NTSB has priority over any investigation conducted by another Federal agency.

(2) The NTSB will provide for appropriate participation by other Federal agencies in any NTSB investigation. Such agencies may not participate in the NTSB's probable cause determination.

(3) The NTSB has first right to access wreckage, information, and resources, and to interview witnesses the NTSB deems pertinent to its investigation.

(4) As indicated in § 831.9(c) of this part, the NTSB has exclusive authority to decide when and how the testing and examination of evidence will occur.

(5) The NTSB and other Federal agencies will exchange information obtained or developed about the accident in the course of their investigations in a timely manner. Nothing in this section prohibits the NTSB from sharing factual information with other agencies.

(6) Incident command system. The NTSB recognizes the role of incident command systems to address emergencies. The NTSB does not assume the role of a first responder agency.

(i) The NTSB IIC or his designee will participate in the incident command system to identify and coordinate investigative needs related to the preservation and collection of information and evidence.

(ii) The NTSB may collect information and evidence from the incident command in a timely and reasonable manner so as not to interfere with its operations.

(b) Investigations by other Federal agencies. (1) Nothing in this section limits the authority of any Federal agency to conduct an investigation of an accident or incident under applicable provisions of law or to obtain information directly from parties involved in, and witnesses to, a transportation accident. Other agencies are expected to coordinate with the NTSB IIC to avoid interference with, and duplication of, the NTSB's investigative efforts. These agencies will not participate in the NTSB's probable cause determination.

(2) The NTSB recognizes that state and local agencies may conduct activities related to an accident under investigation by the NTSB. These agencies will not participate in the NTSB's probable cause determination.

(3) Except as described in § 831.30 of this part regarding highway investigations, the NTSB may request that a Federal agency provide to the NTSB the results of that agency's investigation of an accident when such investigation is intended to result in safety improvements or remedial action. The NTSB will not routinely request regulatory enforcement records or investigation results.

§ 831.6 - Request to withhold information.

(a) Applicability. This section applies to information the NTSB receives from any source that may be subject to the Trade Secrets Act (18 U.S.C. 1905) or the Freedom of Information Act (FOIA, 5 U.S.C. 552).

(b) Disclosure. The NTSB is authorized by 49 U.S.C. 1114(b) to disclose, under certain circumstances, confidential commercial information that would otherwise be subject to penalties for disclosure under the Trade Secrets Act, or excepted from disclosure under FOIA. The NTSB may exercise this authority when disclosure is necessary to support a key finding, a safety recommendation, or the NTSB's statement of probable cause of an accident.

(c) Disclosure procedures. Information submitted to the NTSB that the submitter believes qualifies as a trade secret or as confidential commercial information subject either to the Trade Secrets Act or Exemption 4 of FOIA must be so identified by the submitter on each page that contains such information. In accordance with 49 U.S.C. 1114(b), the NTSB will provide the submitter of identified information (or information the NTSB has reason to believe qualifies as subject to the Trade Secrets Act or Exemption 4 of FOIA) the opportunity to comment on any disclosure contemplated by the NTSB. In all instances in which the NTSB decides to disclose such information pursuant to 49 U.S.C. 1114(b) or 5 U.S.C. 552,the.

(d) Voluntarily provided safety information. (1) The NTSB will not disclose safety-related information voluntarily submitted to the NTSB if the information is not related to the exercise of the NTSB's investigation authority, and if the NTSB finds disclosure of the information might inhibit the voluntary provision of that type of information.

(2) The NTSB will review voluntarily provided safety information for confidential content, and will de-identify or anonymize any confidential content referenced in its products.

(e) Other. Any person may make written objection to the public disclosure of any other information, such as interview summaries or transcripts, contained in any report or document filed, or otherwise obtained by the NTSB, stating the grounds for such objection. The NTSB on its own initiative or if such objection is made, may order such information withheld from public disclosure, when, in its judgment, the information may be withheld under the provisions of an exemption to the FOIA (see part 801 of this chapter), and its release is found not to be in the public interest.

§ 831.7 - Representation during an interview.

(a) Any person interviewed in any manner by the NTSB has the right to be accompanied during the interview by no more than one representative of the witness's choosing. The representative—

(1) May be an attorney;

(2) May provide support and counsel to the witness;

(3) May not supplement the witness's testimony; and

(4) May not advocate for the interests of a witness's other affiliations (e.g., the witnesses employer).

(b) An investigator conducting the interview may take any necessary action (including removal of the representative from the interview) to ensure a witness's representative acts in accordance with the provisions of paragraph (a) of this section during the interview, and to prevent conduct that may be disruptive to the interview.

§ 831.8 - Investigator-in-charge.

In addition to the subpoena and deposition authority delegated to investigative officers under this chapter, a person designated as IIC for an investigation is authorized to—

(b) Subpoenas. The NTSB may issue a subpoena, enforceable in Federal District Court, to obtain testimony or evidence related to an accident, including but not limited to personal electronic devices.

(1) The NTSB's authority to issue subpoenas includes access to medical records and specimens.

(2) For purposes of the Health Insurance Portability and Accountability Act of 1996 (HIPAA), Public Law 104-191, and the regulations promulgated by the DHHS, 45 CFR 164.501 et seq., the NTSB is a “public health authority” to which protected health information may be disclosed by a HIPAA “covered entity” without the prior written authorization of the subject of the records. In addition, the NTSB may issue a subpoena to gain access to such information.

(c) Examination of evidence. In accordance with 49 U.S.C. 1134(d), the NTSB has exclusive authority to decide timing, manner and method of testing and examination of evidence, and extraction of data.

§ 831.10 - Autopsies and postmortem testing.

When a person dies as a result of having been involved in a transportation accident within the jurisdiction of the NTSB—
