Delta to Replace APUs in Effort to Address Toxic Fume Surge

Delta is upgrading the engines on its Airbus jets to stop dangerous fumes from getting into the air people breathe.

These fumes, caused by oil leaks, can make passengers and crew sick.

The problem is mostly in a third engine called the APU.

Delta is replacing these APUs.

The APU helps run the plane's systems when the main engines aren't on.

This helps reduce instances where the air gets contaminated.

This issue has been an ongoing concern, prompting the airline to take corrective action to ensure passenger and crew safety.

This will lead to a more comfortable environment for everyone.
