I know that places where they used to, like Australia, no longer do that. I don't believe the U.S. has any regulations on that. I confess I don't know the details for Germany, but Lufthansa Technik has actually grown into a global maintenance group and I don't believe that Lufthansa is actually required to utilize them. But I confess I don't know the details on that. I'd say the norm throughout the world is no restrictions on where maintenance has to be done.
