The Schenk Law Firm represents commercial pilots, flight crew, and passengers harmed by toxic cabin air exposure. Our active docket includes airline pilots with exposure histories spanning single fume events and repeat, cumulative exposures across multiple flights. Aerotoxic syndrome can cause lasting neurological damage, chronic respiratory illness, diminished cognitive function, and — for career aviators — loss of the FAA medical certification that sustains their livelihood.
Our legal team has the medical, industrial, and aviation experience to handle an aerotoxic syndrome lawsuit against the aircraft, engine, and component manufacturers responsible. We are here to guide you through the complexities of your case and ensure you receive the justice and compensation to which you are entitled.
Aerotoxic syndrome is a medical condition caused by inhaling contaminated cabin air on commercial aircraft, producing neurological, respiratory, and cognitive injuries that can persist for months or years after a single flight. The term covers the same cluster of harms as toxic cabin air exposure, fume events, and bleed air contamination. The sections below explain how the contamination happens and who is most at risk.
Most modern jet aircraft — the Boeing 787 is the notable exception — pressurize the cabin using bleed air drawn directly from the engine compressor. Reported fume events span Boeing and Airbus narrow-body and wide-body fleets, including the Airbus A320 family (A320, A321, A321neo), the Boeing 737 family, and the MD-80 series previously operated by major U.S. carriers.
When engine oil or hydraulic-fluid seals fail, those lubricants leak into the bleed air stream and enter the cabin. The most dangerous compounds are tricresyl phosphates (TCPs). TCPs are organophosphates, a chemical class that also includes certain pesticides and nerve agents. Like other organophosphates, they inhibit cholinesterase activity and affect the central nervous system. A fume event is the visible or smellable moment of contamination; the chemical exposure itself often continues long after the smell is gone.
Spend the most time breathing pressurized cabin air and account for the majority of filed claims. Cases range from the 2011 Boeing settlement with Terry Williams to the $30 million Airbus claim filed in January 2026.
Exposed during takeoff, landing, and climb, when bleed air flow is highest. Pilots are uniquely vulnerable to cumulative exposure: a single career can include multiple fume events across different aircraft, and each exposure can compound neurological injury.
In our docket, pilots have reported progressive symptoms that partially resolve between events but deepen after repeated exposure — a pattern consistent with the toxic encephalopathy diagnosed in the 2020 JetBlue workers' compensation award.
A single fume event can cause acute or long-term injury, as alleged in the December 2025 $40 million Boeing passenger suit. Infants, pregnant travelers, and anyone with a respiratory or neurological condition face elevated risk.
The symptoms of aerotoxic syndrome fall into three categories: short-term reactions during or shortly after the flight, legally relevant and continuous patterns that connect a specific fume event to a diagnosed injury, and long-term neurological damage that may appear weeks or months later.
Many pilots and crew experience more than one fume event in a career. Symptoms that partially resolve between exposures often return, deepen, and become persistent after subsequent events. The clinical literature and our own docket support the pattern: repeat low-to-moderate exposures can produce neurological injury comparable to or worse than a single catastrophic event.
Documenting each event — date, flight number, aircraft type, and the specific symptoms that followed — is critical to establishing cumulative causation.
Symptoms that emerge during or in the days and weeks following a flight — particularly where symptoms worsen or become persistent after subsequent exposures — point to a viable claim. Delayed onset is common in aerotoxic cases and does not defeat causation.
Flight logs documenting an odor, smoke, or fume event, and matching symptoms among other crew or passengers, materially strengthen the claim. Medical records diagnosing toxic encephalopathy, organophosphate exposure, or RADS strengthen the case significantly.
Anyone injured by toxic cabin air (crew or passenger) may have grounds to file an aerotoxic syndrome lawsuit. The legal theory depends on your role on the aircraft.
Commercial pilots have strong product liability claims against aircraft manufacturers and engine manufacturers whose bleed air systems introduced contaminated air into the cabin. Workers' compensation may be pursued in parallel, but manufacturer liability typically drives the larger recovery, including for loss of earning capacity where a pilot can no longer maintain an FAA medical certificate.
Cabin crew spend the most time breathing pressurized cabin air and are most likely to develop chronic aerotoxic injury. Most claims are brought under product liability law against Boeing, Airbus, or the engine manufacturer, or under negligence theories against the carrier for failing to warn or act on known fume events.
Passengers can sue under product liability and negligence, and, if a specific fume event caused injury, directly against the airline. Frequent flyers with documented cumulative exposure and a diagnosed neurological injury are a growing category of claimant, especially after the December 2025 passenger-led suit against Boeing.
Fast action protects both your health and your claim. Take these five steps as soon as you suspect a fume event exposure.
