Which Law Reaches Your Claim — Federal, State or International Treaty
Aviation law works in layers, and keeping them separate is one of the first things that shapes any case. Which layer applies can change the deadline, the damages rules and the court.
If a pilot, operator or maintenance company broke a federal safety rule, that can matter to your claim, but it is not the end of the question. Title 14 of the Code of Federal Regulations sets safety standards for aircraft operations, pilots, maintenance and equipment. A violation of one of those rules may be relevant to a negligence claim, but it does not by itself establish liability; the claim still has to show causation and harm.
State tort law, meaning the law of negligence and product liability, governs most claims arising from domestic aviation accidents. That is where limitation periods, comparative or contributory fault rules (how a court treats fault shared among several parties) and damages rules come from, and they differ from state to state. No state's rule, California's included, is the rule everywhere. A crash can also involve more than one state: the state of departure, the state where the aircraft went down, and the states where the parties are based.
If your flight crossed an international border, a treaty may set the rules instead. The Montreal Convention (the Convention for the Unification of Certain Rules for International Carriage by Air, 1999) governs claims against air carriers for passenger death, injury or delay on international flights. Where it applies, it sets its own rules for liability and its own time limit, and it can sit alongside or in place of the state-law rules that would otherwise apply.
The Federal Tort Claims Act, discussed above, is the separate federal framework for claims against the United States, with its own procedures and time limits.
For families after a death, 49 U.S.C. § 1136 adds a federal layer of support. After an accident within U.S. airspace involving an air carrier or foreign air carrier, resulting in any loss of life, and for which the NTSB will be the lead investigative agency, the NTSB's Chairman must designate a director of family support services as the families' federal point of contact and a liaison with the carrier, and designate an independent nonprofit organization to coordinate emotional, psychological and family support services. The NTSB also has primary federal responsibility for facilitating the recovery and identification of fatally injured passengers in those accidents. Under § 1136(g)(2), after an accident involving an air carrier providing interstate or foreign air transportation, or a foreign air carrier accident within the United States, no unsolicited communication about a potential personal-injury or wrongful-death action may be made by an attorney or any potential party to the litigation to an injured person or a relative before the 45th day following the date of the accident.
For you, the framework that applies can decide the deadline, the damages rules and the court, and it depends on the type of flight, the route and the parties involved. Sorting out which layer governs is often among the first things a conversation with an attorney addresses.
