The Cabin Air Safety Act of 2026 requires airlines to improve how they monitor and respond to contaminated air in aircraft cabins, particularly from engine oil and hydraulic fluid fumes. Airlines must install real-time air quality monitoring equipment within 180 days to detect carbon monoxide and other contaminants in the air supply system, and pilots must receive training on isolation procedures to address dangerous air quality. The bill also mandates that flight attendants, pilots, mechanics, and emergency responders receive annual training on recognizing and responding to fume events, and establishes a standardized reporting system where crew members can voluntarily report these incidents to the Federal Aviation Administration. Additionally, the FAA must investigate any reports involving crew members or passengers requiring medical attention beyond first aid, and must publish aggregated incident data on a public website to improve transparency and safety oversight. The bill authorizes necessary appropriations for the FAA to implement these requirements and does not apply to helicopters.
