The NTSB Investigation and What It Means for Your Civil Claim
The National Transportation Safety Board (NTSB) is the independent federal agency that investigates transportation accidents. For an aircraft accident within its authority, 49 U.S.C. § 1131 says the Board "shall investigate or have investigated (in detail the Board prescribes) and establish the facts, circumstances, and cause or probable cause of" the accident, which is the inquiry a family is often waiting on. The same section generally gives the Board's investigation priority over any investigation by another federal agency, with an exception: if the Attorney General, in consultation with the Chairman of the Board, determines and notifies the Board that circumstances reasonably indicate that the accident may have been caused by an intentional criminal act, the Board "shall relinquish investigative priority to the Federal Bureau of Investigation," though that relinquishment does not otherwise affect the Board's authority to continue its investigation. Other agencies may participate, but the statute says they "may not participate in the decision of the Board about the probable cause of the accident."
A probable cause is the NTSB's own determination of what most likely caused an accident. A preliminary report is an early report issued while an investigation is still open; it is not a statement of probable cause. A final report closes the investigation. Section 1131 requires the Board to make its accident reports available to the public in a free online database, and if a report is not completed within two years of the accident, the Board must report to two congressional committees why, and then report progress every 90 days. Survivors and families can follow the investigation of their own crash through that public database.
For a burn survivor or a grieving family, the most important federal rule is a different one. Section 1154(b) of the same title, 49 U.S.C. § 1154, says:
"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."
In practical terms, a probable-cause finding, whatever it says, is not what decides a claim for damages, and the evidence for a claim has to be developed independently. Section 1154(a) also limits how parties in a lawsuit may obtain cockpit voice or video recordings and their transcripts; a court may allow it only after a private review and a finding that it is needed for a fair trial, and then only under a protective order.
The deadline for a civil claim is set by the law that governs the claim, not by the NTSB's timetable, and the statute itself contemplates investigations that run longer than two years. Someone waiting on the NTSB may weigh that a claim's timing does not follow the investigation's.
