In many of our aviation accident cases, one of the first tasks for investigation is reviewing the report from the National Transportation Safety Board (“NTSB”). The “preliminary” report is generally available within a few days of an accident or incident, and then once further factual information has been obtained and the investigation is deemed complete, the NTSB prepares a “final” version of the report with both a detailed description of the facts obtained and the NTSB’s “probable cause” determination.[1]

We sometimes see the NTSB reports referenced or relied upon in litigation and occasionally must argue our position that certain parts of the report are inadmissible as evidence at trial. There are generally two parts in the NTSB reports that are subject to challenge: (1) the “probable cause” and opinions; and (2) inadmissible hearsay statements from witnesses. 

The NTSB’s Probable Cause Opinions Are Inadmissible In Court.

Under the Federal Aviation Act (“FAA”) as well as case law around the country, at most, only the factual portions of these reports are admissible as evidence in civil litigation. Federal Aviation Act of 1958, § 701(e), 49 U.S.C. § 1154(b)[2].

In North Carolina, the Courts have cited the FAA statute and held that no part of any report of the NTSB relating to any accident or the investigation thereof shall be admitted as evidence or used in any suit or action for damages growing out of any matter mentioned in such report or reports.[3] The Court in Bolick v. Sunbird Airlines, Inc. even went on to explain that our courts have excluded the portions of such reports expressing agency views and opinions, but agreed that factual information was admissible.[4]

To compare, in the case In re Paulsboro Derailment Cases[5], the New Jersey court held that the entire NTSB report was to be excluded from evidence based on the language of 49 U.S.C. §1154(b) that specifically uses the phrase no part” of the accident report may be admitted into evidence. 

Indeed, on the NTSB report itself where the “probable cause” is provided, there is even a notice in a box shaded in gray at the end that explicitly informs the public that such admission into evidence in a civil action is precluded[6]:

In one example, in the Davis v. Cessna case, the Court of Appeals in Arizona specifically held that trial court’s admission of the NTSB’s probable cause conclusion of pilot error was deemed “reversible error.” In other words, the verdict was reversed because the jury had improperly been informed that the NTSB decided the issue by finding the pilot was solely responsible for the crash. 

However, there are cases where the probable cause from the NTSB report was used in court because no objection was made and 49 U.S.C. § 1154(b) was not brought to the court’s attention.[7] These cases are considered anomalies. Thus, upon proper objection by legal counsel, the “probable cause” and opinions in the NTSB report are not admissible in Court.  

Hearsay Statements From Witnesses In The NTSB Report Are Inadmissible In Court.

Additionally, the portions of the NTSB report that are based on witness (or pilot) statements to the NTSB must be scrutinized under the hearsay rule. In the Bolick casethe N.C. Court held that the portions of the NTSB airplane crash investigation report containing hearsay statements by pilots, witnesses and other non-officials who were not present to testify at trial were properly excluded at the negligence trial arising out of an airplane crash.[8]

Likewise, in John McShain, Inc. v. Cessna Aircraft Co.[9], the Pennsylvania court upheld the trial court’s exclusion of the NTSB report “to the extent it consisted of statements of pilots or other witnesses because they constitute inadmissible hearsay.” Some courts around the country will also choose to exclude the entire report to avoid the “arduous” process of weeding through which facts are not hearsay, as a matter of judicial economy.[10] Still, other courts will require the parties to redact the portions of the NTSB report that contain hearsay.[11]

The McShain court went on to state that memoranda submitted to the government by its investigators often contain statements from witnesses, and such memoranda would actually encompass double hearsay. Thus, while factual portions from official investigative reports are admissible under Rule 803(8)(c), “any hearsay contained in the report must also fall under one of the hearsay exceptions” or it should be excluded from evidence. In fact, the Advisory Committee on the F.R.E. also makes clear that Federal Rule of Evidence 803(8)[12] exempts from the hearsay rule only reports by officials; and of course, pilots and other witnesses are not “officials” for this purpose.[13]

It is also important to note that federal law prohibits FAA and NTSB employees or similarly employed government personnel from giving opinion testimony and/or acting as an expert witness concerning an accident in civil litigation. 14 C.F.R. § 13.227 (“An employee of the agency may not be called as an expert or opinion witness, for any party other than the FAA…”) and 49 C.F.R. § 835.3 (“Board employees…shall not give any expert or opinion testimony) (emphasis added).

The policy behind the exclusion of these opinions from NTSB investigations is clear: to assist the FAA in protecting against future accidents.[14] The agency’s investigatory procedures are “not designed to facilitate litigation, and Congress made it clear the Board and its reports should not be used to the advantage or disadvantage of any party in a civil lawsuit.”[15]

Thus, Congress put strict limits on how NTSB materials and employees may be used in civil litigation to keep the NTSB “free of entanglement of such suits” and to ensure that the NTSB “does not exert an undue influence on litigation.”[16] 49 C.F.R. § 835.3(a) (the policy is to exclude reports that express agency views as to probable cause of the accident).

While NTSB employees may testify as to facts, i.e. what they personally observed during investigation, the FAA requires they “shall” decline to testify regarding matters beyond the scope of their investigation and they “shall not give any expert or opinion testimony.” 49 C.F.R. §835.3(b). In our experience, it is unlikely that the NTSB will voluntarily provide anytestimony in a civil lawsuit, and the effort required to compel the NTSB personnel or investigators to testify is cumbersome with a low likelihood of such resulting in any useful testimony or evidence that could not have been obtained elsewhere or by other means.

Thus, upon proper objection by legal counsel, the hearsay testimony contained in the NTSB report is also not admissible in Court.  

This information is important to bear in mind during aviation accident cases, as it might be tempting to rely heavily, but inappropriately, on the investigation the NTSB has undertaken and its reports. The federal law makes it clear that the NTSB reports are not intended to be used in civil litigation, but rather, the NTSB is to do its investigation independent of any potential entanglement in any lawsuit.

The formatting of the NTSB reports has changed and the Probable Cause section may be incorporated into the final report and not as a separate document as was done before; questions arise as to how courts may view this formatting and the extent to which the report will be excluded.
