Airbus investigates corrosion issue in some A220 jets including US operators

Delta Air Lines, the world's largest operator of the Airbus A220, has observed corrosion on multiple models requiring treatment with additional lubricating chemicals. The airline stated that this issue has not affected flight schedules or led to any cancellations.

Delta assured that its sophisticated aircraft maintenance team is prepared to handle such issues. "Our technical experts think that these kinds of issues are not inherently surprising for new, clean-sheet aircraft," said a Delta representative.

Other U.S.-based carriers like JetBlue and Breeze Airways also operate dozens of A220 jets and have acknowledged awareness of the corrosion issue. Both airlines emphasized their commitment to safety and reported no impact on their fleets' reliability.

Globally, other operators of the Airbus A220 include Air Canada, Air Baltic, SWISS, and Air France.

Industry experts note that it is not uncommon for newly-built aircraft to face corrosion-related issues on non-structural components designed with new materials. Despite initial concerns, all parties involved affirm that this development will not affect operational safety or reliability.
