What Determines Liability in an Aviation Case?

In negligence cases, the plaintiff bears the burden of proving by preponderance of evidence that the defendant owed a duty, breached it, and directly caused the loss. The standard of care varies by defendant role. An aircraft manufacturer must design and test to industry standards. A maintenance provider must comply with Federal Aviation Administration (FAA) directives and manufacturer protocols. A pilot or operator must follow applicable regulations and exercise reasonable judgment. Courts assess breach by comparing actual conduct to what a reasonably prudent professional in that role would have done under similar circumstances.

Causation is often the dispositive hurdle in aviation cases. An expert must establish that the defendant's breach directly caused the accident or incident, not merely that it created a risk. Competing causation theories, latent defects, pilot error, weather, or mechanical failures unrelated to the defendant's conduct can undermine the case. Document preservation becomes critical immediately after an incident because aircraft components, maintenance records, and flight data may be subject to regulatory holds or spoliation risks if not properly secured.

Preserve all physical evidence and records within hours of an incident. Aircraft wreckage, engines, avionics, and structural components must be secured and photographed before removal or alteration. Request that your aviation expert or investigator participate in any National Transportation Safety Board (NTSB) investigation if the incident falls under NTSB jurisdiction, or coordinate with local authorities if it does not.

Maintenance logs, flight records, pilot qualifications, fuel samples, weather data, and communications records form the documentary foundation of the case. Issue preservation notices immediately to third parties holding these materials to prevent destruction and lay the groundwork for formal discovery demands. In federal court, Federal Rule of Civil Procedure 26(b)(3) protects attorney work product, but factual materials like photographs, measurements, and expert reports are typically discoverable.

Determine whether the incident falls under federal or state jurisdiction. Federal question jurisdiction may apply if the case involves federal aviation law or a claim against a federal agency. Diversity jurisdiction may apply if parties are from different states and the amount exceeds $75,000. Choice of jurisdiction affects procedural rules, available remedies, and appeal pathways.

Aviation cases often proceed in federal court under diversity or federal question jurisdiction. Federal Rule of Civil Procedure 26(a)(2) requires that each party disclose expert reports at least 90 days before trial, containing the expert's opinions, basis for those opinions, and curriculum vitae. Failure to timely disclose can result in exclusion of expert testimony, a severe sanction that undermines liability theories.

In state court, particularly New York, aviation cases may be filed in Supreme Court or a specialized commercial court depending on county and complexity. State discovery rules generally allow broad requests for documents and depositions, but timing and notice requirements are equally strict. Service of process and notice requirements are foundational. Verify that all defendants have been properly served in accordance with federal or state rules. Service defects can result in dismissal or delay.

If your corporation is the defendant, several affirmative defenses can reduce or eliminate liability. Comparative negligence permits a defendant to argue that the plaintiff's own conduct contributed to the loss, reducing recovery proportionally in most jurisdictions. In aviation cases, pilot error, improper preflight inspection, or failure to follow manufacturer instructions can support this defense.

Assumption of risk applies when a plaintiff knew of a hazard and voluntarily accepted it. Charter passengers or test pilots may have signed liability waivers. Courts enforce such agreements if they are clear and conspicuous, though waivers do not shield a defendant from gross negligence or willful misconduct in many jurisdictions.

Regulatory compliance is a partial defense. If your corporation followed all FAA maintenance directives, adhered to manufacturer specifications, and complied with applicable regulations, that evidence supports a defense against negligence claims. However, regulatory compliance does not automatically defeat a strict liability claim based on a defective product or design.

Causation gaps and alternative causation theories are powerful defense tools. If the accident resulted from multiple contributing factors, pilot error, weather, or mechanical failure unrelated to the defendant's conduct, the defendant can argue that its alleged breach did not directly cause the loss. Expert testimony is essential to establish or rebut causation. An administrative case or FAA enforcement action arising from the same incident may be stayed pending resolution of the civil case.

Aviation cases are expert-intensive. Your corporation will need one or more experts in aircraft maintenance, design, pilot operations, weather analysis, or accident reconstruction, depending on the liability theory. An expert must be qualified by education, experience, and specialized knowledge. Courts apply the Daubert standard in federal court to test whether expert testimony is reliable and relevant.

Retain your expert early and ensure they have access to all physical evidence, maintenance records, and incident data. An expert report must contain a clear methodology, identification of materials reviewed, and opinions stated with reasonable certainty, not speculation. Black box data, cockpit voice recordings, and flight data recorders are often the most probative evidence. The NTSB typically controls access to these materials during its investigation. Once the NTSB investigation concludes and a final report is issued, parties may request docket materials.

Parties alleging design defects must present evidence that the aircraft or component was defective when it left the manufacturer's control, not damaged in operation or maintenance. Strict liability claims require proof of a defect that made the product unreasonably dangerous. Negligent design claims require proof that a reasonable alternative design was available and feasible.

The statute of limitations for aviation negligence claims varies by jurisdiction and type of injury. In New York, the general negligence statute of limitations is three years. Tolling provisions may extend the deadline in limited circumstances if the defendant is outside the state, if the plaintiff is a minor, or if the injury was not discoverable despite reasonable diligence. However, courts interpret tolling narrowly.

Compliance with federal notice requirements can also affect deadlines. If the incident involves a commercial aircraft or occurs at a federally controlled airport, notice to the FAA or NTSB may be required within specific timeframes. Establish an internal tracking system and calendar all critical dates with advance reminders to your legal team. Missing a single deadline can result in preclusion of evidence, dismissal of claims or defenses, or default judgment.

Evaluate early settlement opportunities and insurance coverage in parallel with litigation preparation. Many aviation incidents involve multiple insurance carriers, and coordination of defense among co-defendants may be necessary. Consider whether alternative dispute resolution, such as mediation or arbitration, offers a faster or more cost-effective resolution than trial.
