More Airbus A350s must now get their oxygen tanks checked for defects

The US aviation regulator is expanding a mandatory inspection for certain Airbus A350 airplanes. More of these planes must now have their oxygen containers and nearby panels checked for defects.

Airlines operating Airbus A350s will now have to ground more planes for these inspections. This means more maintenance costs and potential flight disruptions for a wider range of aircraft. The FAA is responding to a known safety issue that affects more planes than previously thought.
