You don't finish your activity on the aircraft once you have completed assembly of the 65 aircraft. You will have maintenance overall and scheduled maintenance at 400 and 800 hours, with that interval. That will require basically the same tooling and the same industrial capabilities that are required to manufacture the aircraft. Also, for the insertion of new capabilities, this normally comes as a software load, but most likely they require some hardware changes as well, and you need to be prepared for that.
