Keywords: aeroelasticity, flutter, eigenvalue, sensitivity

The paper describes the airliner wing flutter sensitivity analysis. It defines the influence of inertia and stiffness parameters changes to the stability. The sensitivity coefficients were calculated with respect to the eigenvalue type of responses (natural frequencies) and flutter type of response (decay rate for the flutter mode).
