The goal of the presented research is the piezoceramics transducer (PZT) electromechanical impedance as a function of the tightness loosing in a bolt-joint of some aircraft component. Object of investigation: the bolt-joint of the helicopter Mi-8 tail beam. One example of this kind of a bolt-joint and the scheme of possible fatigue damage is shown on Figure Three sensors 27301 (Pz 27) 6.35x6.35x1 mm (In Sensor) were glued on each frame by Electrically Conductive Adhesive EPO-TEK EE129-4.
