The object of diagnostics is the Sukhoi Superjet 100 (RRJ) elevator. The elevator skin is made of 7-layer composite carbon-fibre-reinforced polymer. In the result of the test the load of lighting was determined as 110% of destructive load. It can be concluded that potential structural changes of composite material layers may occur in a much wider area than it is visually observable. The Acoustic Emission method (AE) is based on the register and analysis of acoustic waves occurring in the process of plastic deformation and destruction (crack growth) of the objects of diagnostics. The results of the research show that application of the AE testing method is a rational way for composite material non-destructive testing in civil aviation.
