Back in February, the cabin of Delta flight 876 filled with hazy smoke mid-flight, forcing the plane to make an emergency landing.
“A person breathes [the fumes] into their lungs, it circulates around, and then it gets into their brain and can affect the other parts of the nervous system,” he explained.
“I felt like I might die, and I thought, you know, I wonder what my mom is going to think, this, I went to work, and you know, I may not make it,” she said at the time.
A Wall Street Journal investigation published over the weekend found the fume issue was most common on the popular Airbus A320 family of narrowbody jets.
“We are committed to continuously enhancing our products, working closely with operators and regulators to ensure the best possible cabin environment for passengers and crew,” Airbus said.
“Every aircraft should really have the filtration system on it to avoid those toxins from getting into the circulated air in the cabin,” said Sara Nelson, president of the Association of Flight Attendants-CWA.
Nearly all commercial jets “bleed” fresh air in from the plane’s engines. It’s then fed through an air conditioner and into the cabin. But if an engine seal fails, oil and other potentially toxic particles can be released. According to reports filed with the FAA, fumes are often compared to the smell of dirty socks.
“In rare instances, mechanical issues such as failures of an engine oil seal or recirculation fan bearings can cause fumes to enter the cabin. Airlines are required to report these incidents to the FAA,” the agency said. “The FAA investigates the causes and makes sure they’re fixed before the aircraft returns to service.”
Boeing said in a statement, “Independent researchers, universities, industry groups, and government agencies have conducted extensive research on cabin air quality. The results repeatedly demonstrate that contaminant levels on aircraft are generally low and that health and safety standards are met. Based on that research, the world’s five leading aerospace medical associations have rejected a connection between cabin air and significant health effects, and no aviation regulator has determined that additional safety regulations are required. Boeing continues to work with scientists to improve our understanding of cabin environmental factors and to study potential new technologies.”
