An aviation accident is often a catastrophic event governed by an intersecting matrix of federal regulations and distinct state tort laws. In the Greater St. Louis metropolitan area, establishing legal liability requires a deep understanding of bi-state jurisdictions. Whether an avaiation incident occurs at a commercial hub like St. Louis Lambert International Airport (STL), a regional facility like the Spirit of St. Louis Airport in Chesterfield, or a Metro East Illinois facility like MidAmerica St. Louis Airport, the legal path to financial recovery depends entirely on where the aircraft was operating and which laws apply to your claim.
If you or a loved one has suffered severe injury or wrongful death in a commercial airline disaster, charter flight failure, or private general aviation crash, our bi-state legal team at The Cagle Law Firm protects victims across both Missouri and Illinois.

Unlike typical motor vehicle collisions, aviation litigation immediately introduces federal oversight alongside state common law. The Federal Aviation Administration (FAA) sets strict operational standards, while the National Transportation Safety Board (NTSB) conducts technical investigations to determine probable cause. However, the NTSB does not assign legal fault or award damages. Financial recovery is dictated strictly by state civil statutes.
Because the St. Louis media market and commuter network seamlessly cross the Mississippi River, an aviation case can involve a flight taking off in Missouri and crashing in Illinois, or an aircraft maintained by an Illinois corporation operating out of a Missouri airfield. Determining venue and applicable law is the first critical step in building a successful claim.
The outcome of your case can vary significantly depending on whether Missouri or Illinois law governs your injury or wrongful death claim. Our firm explicitly manages the stark legal differences between these two states:

Aviation accidents rarely stem from a single isolated failure. Developing a successful multi-million dollar recovery plan requires isolating the exact tier of flight operations under the Federal Code of Regulations (CFR):
Under (14 CFR Part 121), Commercial airlines are classified as “common carriers.” Under both Missouri and Illinois law, common carriers owe the highest duty of care to their passengers. Liability may fall upon the airline for pilot error, inadequate crew training, failure to properly monitor weather conditions (such as severe convective turbulence over the Midwest), or improper cabin safety management.
Under (14 CFR Part 135), Charter flights operating throughout the bi-state area are subject to strict regulations, though they often operate with less corporate oversight than major commercial fleets. Liability frequently involves negligent maintenance protocols, pilot fatigue, or mechanical failure of regional turboprops and light jets.
Under (14 CFR Part 91), General aviation covers private planes, corporate jets, and recreational flights. Crashes in this category frequently occur due to pilot spatial disorientation, fuel exhaustion, or substandard maintenance executed by independent aviation mechanics.
If your flight originated or was scheduled to land outside the United States, your recovery is governed exclusively by the international treaty known as the Montreal Convention. Article 17 of the Convention holds air carriers strictly liable for passenger injuries or death up to specific international limits (measured in Special Drawing Rights), regardless of proof of negligence. It also dictates specific global venues where your lawsuit must be filed.
Our legal team collaborates immediately with independent aerospace engineers, meteorologists, and human factors experts to preserve critical evidence long before the NTSB issues its final report. We meticulously analyze:
Jurisdiction depends on several competing factors, including the principal place of business of the airline, where the aircraft maintenance occurred, and the residency of the victims. An experienced bi-state lawyer will evaluate whether filing in a Missouri circuit court or an Illinois circuit court provides the most strategic advantages regarding discovery rules and jury dynamics.
Air traffic controllers are employees of the federal government (FAA). Claims against them must proceed under the Federal Tort Claims Act (FTCA). This requires filing a comprehensive administrative claim with the appropriate federal agency within two years of the incident before any formal lawsuit can be initiated in a United States District Court.
Surviving family members in both Missouri and Illinois may pursue financial compensation for funeral and burial expenses, the loss of financial support and future earnings of the deceased, medical bills incurred prior to passing, and non-economic damages for the loss of companionship, guidance, consortium, and deep emotional grief.
If you have been seriously injured due to an aviation incident or if you have lost a family member, our attorneys are here to help. We represent seriously injured victims and wrongful death victims of aviation incidents.
