Etihad Airways has opened its first US line maintenance base at Chicago O’Hare Airport.

The base will perform all scheduled and non-scheduled line maintenance for Etihad Boeing 777 aircraft flying daily service from Abu Dhabi. It will also provide line maintenance services for Air Berlin Airbus A330s, operating 3X-weekly from Berlin beginning March 23 and increasing to 5X-weekly in summer 2013. Etihad said it will also offer full technical handling “for at least one other carrier.”

The new Chicago facility will be staffed with Abu Dhabi-trained line maintenance aircraft engineers with additional engineering support to be provided by Chicago-based Flightcheck LLC.

Etihad Airways president and CEO James Hogan said, “As partners, it makes operational and commercial sense to work together on issues such as common maintenance, and we expect the synergies and efficiencies we achieve through this specific integration to deliver tangible benefits for both our businesses.”

The two carriers launched a partnership in December 2011.

The maintenance services in Chicago will include transit, daily and weekly checks, scheduled engineering services, and fault repairs for aircraft systems and cabin issues. Etihad operates line maintenance facilities in Dublin, Lahore, London-Heathrow, Manchester, Melbourne and Sydney.
