Safe Air on Airplanes Act

HR 4994, the Safe Air on Airplanes Act, requires the Federal Aviation Administration to update regulations to phase out bleed air systems in aircraft. It prohibits new aircraft designs from using these systems, mandates filters to remove oil fumes in new aircraft by 2031 (7 years after enactment), and sets a 30-year phase-out schedule for existing aircraft designs (25% without bleed air by 2031, 50% by 2041, 100% by 2051). The bill directly affects aircraft manufacturers and airlines, as it changes requirements for cabin air systems that pull engine air for ventilation. These changes focus on modifying manufacturing standards and air quality systems in turbine and turbo-prop aircraft.
