What's Happening?
Delta Air Lines is replacing auxiliary power units (APUs) on over 300 Airbus A320 planes due to toxic fumes leaking into the cabin air. These fumes, caused by oil entering the APU's compression chamber, pose health risks to passengers and crew. The replacement process began in 2022 and is nearly complete. Delta is also exploring new synthetic turbine oils to address the issue, which has been a concern across the industry.
Why It's Important?
The replacement of APUs by Delta Air Lines is a significant measure to enhance passenger and crew safety, addressing a critical issue in aircraft maintenance. This initiative reflects the airline industry's commitment to improving air quality standards and reducing health risks associated with air travel. The move may influence other airlines to adopt similar practices, potentially leading to industry-wide improvements in aircraft safety protocols.
