Keywords: aircraft design, stress analysis, landing gear, structural mechanics, structural testing

FEM analysis is compared with the real structural test results and agreement confirmed. This can help to reduce the number of structural tests and reducing the costs and time necessary to develop a new or modified landing gear. The results of analysis confirm that precision of the FEM stress analysis in comparable with the test of real structure depending mainly on material and geometrical non-linearity included to the FEM analysis.
