More Airbus planes must fix faulty oxygen tanks, including a new model

The US aviation regulator is expanding an existing order for Airbus to replace faulty oxygen tanks on its planes. This new rule adds a recently certified Airbus model to the list of affected aircraft.

Aviation safety rules are often updated to include new aircraft models as they are certified. This ensures that safety issues found in older designs are addressed across the entire fleet. It means that a known safety problem will not be allowed to persist on newer planes.
