In the following paper, general principles, methodology, and tools for crash analysis of the large aircraft are presented. Attention was focused on the crash of the Polish presidential airplane TU-154M on April 10, 2010, in Smolensk. The way of finite-element method (FEM) model developing that can be used in crash analysis using LS DYNA software was shown. A Tu-154M airplane geometry model was obtained using reverse engineering methods. Moreover, the parameters of a wingtip, especially a mass and the inertia tensor, have been reverse engineered using drawings and specialized tools for crash analysis. During analysis, the Johnson–Cook material model for structure strength elements and wood material model for a tree were used. In addition, aerodynamic forces were taken into account. An aerodynamic analysis was aimed to take into account the effect of ground proximity and influence of the flow around an aircraft, including tip vortices, to the flight of the unconstrained wingtip.
