regulations to the utmost extent possible with the international community, to ensure the safe operation of aircraft between oversight systems. The U.S. plays a very active role within the global regulatory community and within ICAO to ensure that all international standards are technically feasible, economically viable, data-driven and allow for universal implementation. That being said, all nations have an obligation to put in place regulations within their national oversight structure that are commensurate with the operational realities of that system. In the U.S., regulations are intended to be performance-based, which allows greater flexibility for industry while still ensuring a minimum level of safety. This view may not always be reflected in the certification standards of other nations, as there may be certain unique operational circumstances that require a more prescriptive approach within that system. We put a lot of effort into working with the international community to minimize the differences between national systems and, when necessary, to try to understand them so that we can support our industry with innovative solutions to minimize the impact of these differences. Some examples of the efforts undertaken by the FAA within ICAO include active leadership on technical working groups, which are tasked with identifying viable international standards for adoption within the ICAO annexes. On the bilateral front, the FAA meets regularly with foreign counterparts to identify differences in our approaches to certification regulations, and seeks to harmonize these standards as much as possible. We invest a lot of resources into working with our bilateral partners, such as EASA, TCCA and ANAC, to develop rules as well as implementation guidance, so we all can be assured of a high level of commonality in the way we apply

our rules and policy. Harmonization is a priority for the FAA, as it allows us to optimize our reliance on the robust systems of our bilateral partners. Some examples of recent successes in our harmonization efforts include: • Collaboration with EASA to harmonize the core technical standards of the European
