“The Two Largest MRO Facilities in the World

Our central location has made us a hub for MRO activity where a strong, skilled workforce rebuilds and repairs aircraft, parts, components, and engines.

American Airlines runs the largest single-site commercial aircraft MRO facility in the world at Tulsa International Airport. Oklahoma is also home to Tinker AFB, the largest Department of Defense air depot. Located in Oklahoma City, the Mike Monroney Aeronautical Center is our nation’s hub for FAA.”
