    This research proposes to design a Goland wing structure using a two-step approach that concerns the last step uncertainty. The first step starts with performing the design optimization for multi-purposes followed by the design of wing mass, stress, and buckling factor and the reliability test of all solution set. Due to the aircraft wing being subjected to aerodynamics loads, both the structure failure and the material can deviate from the optimum result. A vortex lattice method is used for aerodynamics analysis, the finite element method is analyzed by the structural failure. These techniques are expected to reduce the complexity of Reliability-Based Design Optimization (RBDO). The Latin hypercube sampling method is used to quantify uncertainties of the aircraft wing structural design so that the experimental results including the solution sets are more acceptable and reliable which the proposed approach can be an alternative way for the RBDO technique.
