The constant increase in competitiveness among companies in the aeronautical sector demands that the industry reinvent itself and is always looking for new options to make its product more attractive. In this sector, each kilogram removed from the final product turns into an increase in efficiency and performance gain, which turns into an increase in operating profit. That is why weight reduction is a constant goal in aviation. As a tool to achieve this goal, the use of topological analysis during product design has great potential. This paper proposes the comparison between the static analysis in rupture of a rib, of typical use in wings, before and after the topological analysis, made through a finite element model using the OptiStruct software. The results obtained from stress distribution and maximum displacement are presented and commented, as well as the points of attention when using this approach
