U.S. aircraft parts figure prominently in U.S. competitiveness in global aerospace trade. In contrast to other aerospace sectors, job creation at small and medium enterprises can especially benefit from increased exports of aircraft parts. This book provides commentary on changing market dynamics. It helps inform U.S. suppliers of aerospace products of what the U.S. Department of Commerce’s International Trade Administration (ITA) considers to be leading markets for exports of U.S. aircraft parts. Top markets for future growth in U.S. aircraft parts exports are generally those that are leading exports markets overall for U.S. products (e.g., large European economies, Japan, China and Singapore).
