Expansion of the advanced composite usage and application of innovative design for wing structure lead the commercial aircraft to weight reduction and to improvement of energy efficiency. The five-year program of affordable and light weight wing box development has been conducted. The target of this program, 15% lighter weight and 50% less in parts count compared with conventional aluminum built-up structure, has been proved to achieve by development and verification of advanced material, affordable fabrication techniques and optimum design method. In addition, substantiation plan of the structure is also established and the development process follows the plan.
