The objective of this study is to reveal the margin of safety for the rectangular wing mid section of a two-seater trainer aircraft. The numerical and theoretical analysis have been carried out to find the bending stress and margin of safety values at mid section of an aircraft wing using finite element analysis and K factor method, respectively. The results of the numerical analysis reveal that the maximum stress value is 12.22 kg/mm2 with 0.2% variation with theoretical method. This novel concept could be used to improve the performance and reduce the weight of an aircraft.
