• Mechanism analysis of main landing gear. • Multiple planar four-bar linkages with multiple coupler points. • Analytical kinematics equations for complex mechanism. • Learning design perspectives against failures. The landing gear lifetime is estimated based on the safe-life design concept and its design requires thorough calculations. The individual parts and sub-assemblies must be sensibly designed to function safely and efficiently for the specified design lifetime without failure. In a design process of a main landing gear system, the kinematics/mechanisms analysis shall be first carried out as a primary task for feasibility of the gear retraction/extension with the satisfactory link paths. This paper presents the analytical kinematics analysis of a complex mechanism involving multiple four-bar linkages with multiple coupler points of the main landing gear (MLG) of CN-235 aircraft. The kinematics analyses were performed in order to figure out the overall link positions of the main landing gear mechanism and make scenarios of a deformed component from its designed geometry for possibilities of a lock failed position.
