Leaky Seals on Planes Linked to Pilot and Flight Attendant Brain Injuries

Toxic Air on Commercial Flights

• ✈️ A Wall Street Journal investigation reveals concerns about the safety of air quality on commercial aircraft.
• 💡 In most planes, cabin air is sourced via a process called bleed air, pulled from the engines.
• ⚠️ If seals are worn or damaged, toxic oils can leak into this air, vaporize, and circulate through the cabin.

Neurological Impact and Reported Cases

• 🧠 One neurologist has treated approximately a dozen pilots and over 100 flight attendants for brain injuries allegedly linked to fume exposure over the past 20 years.
• 📈 Cases reportedly spiked in 2017, with a majority of incidents tied to Airbus A320s, though Boeing aircraft have also experienced issues.

Industry and Regulatory Responses

• 💬 Flight attendants have been advocating for manufacturers to implement alternative air systems or specialized filters to prevent fume exposure.
• ✈️ Airbuzz states its aircraft are designed and manufactured to meet all applicable airworthiness requirements.
• 📊 The FAA maintains that cabin air quality is comparable to or better than that found in offices and homes.
• 🏛️ In response to the investigation, a bipartisan bill is being considered in Congress to mandate specialized air filters on airplanes.
