Keywords: nonlinear flight dynamics, dynamical systems theory, bifurcation theory

In this paper we will consider stability and bifurcation analysis based on nonlinear description of the aircraft. Aircraft will be modeled as multibody system. We will study the post fault system dynamics. Basic problem in our approach is adequate modeling of tree play and friction.
