Static strength test is one of the important tests for an aircraft and an important method to verify structural strength and static analysis for an aircraft. To validate the safety of the main landing gear attachment structure of a type of civil aircraft and the results of finite element analysis (FEA) model, a static structural test of the main landing gear attachment structure is performed on the static strength test aircraft. The load,stress/strain and displacement test data are compared with the analysis result of the aircraft finite element (FE) model and detail FE model. The results show that the FEA are in good agreement with test data.
