Human Powered Aircraft (HPA) should be light in weight and have high efficiency because power source of propulsion is human muscles. Airframe structure takes up most of empty weight of aircraft, so weight reduction of structure is very important issue for HPA. In this paper, design/analysis for ultra light weight structure of the HPA developed by Korea Aerospace Research Institute (KARI) is explained briefly. Structural analysis is conducted for main wing sizing.
