This bill, titled the "Airline Travelers Right to Know Act," aims to enhance transparency regarding potential toxic fume exposure on passenger-carrying aircraft. It directs the Federal Aviation Administration (FAA) to establish and enforce a comprehensive policy informing passengers, pilots, and cabin crew about the risks of toxic fumes that could cause permanent health or brain damage. This policy must detail potential acute or chronic impairment and list chemicals known to cause serious health issues present in jet exhaust and fumes. The disclosure policy must be included in pilot and crew contracts and provided to passengers immediately after ticket purchase. Furthermore, operators of passenger-carrying aircraft will be required to ensure passengers acknowledge their understanding of potential toxic fume exposure during the ticket buying process. The policy also mandates information on safety management systems for protection and post-exposure care, including the right for individuals to use cabin oxygen masks during a toxic fume event. The legislation establishes requirements for immediate notification of toxic fume events, with the FAA informing affected customers, flight attendants, pilots, and maintenance technicians once an air carrier confirms such an incident. Air carriers must also inform crewmembers of recent toxic fume exposures on specific aircraft, whether the issue is resolved, and if any crew sought treatment. Importantly, crewmembers gain the right to decline an assignment on an aircraft with an unresolved toxic fume issue without penalty. To ensure compliance, the bill introduces several enforcement mechanisms, including civil penalties for violations of disclosure requirements, false statements, or misrepresentations by operators. A significant civil penalty of $100,000 will be imposed for missing required reports. Additionally, the Secretary of Transportation is mandated to issue regulations requiring the installation of toxic fume sensors on aircraft and the provision of mobile oxygen masks for crewmembers assisting passengers during fume events.
