Abstract: In the first phase of pilots training, stability and manoeuvrability of the airplane play a crucial role for successful and safe education of the pilots. With the aim of researching in the field of longitudinal static stability, the tailplane of the training aircraft Lasta is modified. With the increase of the tailplane span additional loads are generated. All-composite parts of the modified tailplane tip, designed in the CATIA software, and the strength calculation of the new assembly joints, with additional loads have been presented in this paper.
