What the NTSB Investigation Means for a Family's Civil Claim
The National Transportation Safety Board (NTSB) is the independent federal agency that investigates aviation accidents to find their probable cause, meaning its determination of why an accident happened, so that similar accidents can be prevented. It does not decide civil liability.
The NTSB's reports come in stages. A preliminary report is an early, factual account, and it can change as the work continues. It is not a finding. A final report contains the NTSB's completed probable-cause determination. When an investigation is still open, no probable cause has been stated, and families are often left waiting.
Federal law keeps those reports out of civil damages cases. Under 49 U.S.C. § 1154(b): "No part of a report of the Board, related to an accident or an investigation of an accident, may be admitted into evidence or used in a civil action for damages resulting from a matter mentioned in the report." Under subsection (a) of the same section, a party in a judicial proceeding generally may not use discovery to obtain cockpit or surface vehicle recorder recordings, or the still images and parts of recorder transcripts the NTSB has not made public, unless a court, after an in camera review, decides that the material already available does not give the party sufficient information for a fair trial and that the additional discovery is necessary.
The Federal Aviation Administration (FAA) is a separate agency. It writes and enforces the rules for aircraft, pilots and operators, while the NTSB investigates.
For accidents involving an air carrier and loss of life, 49 U.S.C. § 1136, the federal family-assistance statute, applies when the NTSB is the lead investigative agency. Section 1136 requires the NTSB chairman to designate a director of family support services and an independent nonprofit to coordinate family care. It also bars unsolicited communication about a potential injury or wrongful-death action, by an attorney or any potential party to the litigation, before the 45th day after the accident, for accidents involving an air carrier providing interstate or foreign air transportation, or a foreign air carrier in the United States.
Because the reports stay out of court, a civil claim rests on its own evidence: maintenance records, records of airworthiness directive compliance, flight data recorder (FDR) data, cockpit voice recorder (CVR) data, air traffic control communications and the aircraft's logbooks. For a family waiting on a final report, this means the civil side does not depend on the NTSB's conclusion, and keeping track of the investigation's status alongside any separate records can be useful when talking with an attorney.
