The review of FRP structures radius zones ultrasonic non-destructive testing techniques is given in the paper. It is shown that both single-element piezoelectric transducers and phased arrays can currently be used to solve this problem. It is necessary to use special tools for positioning and creating an acoustic contact with both types of transducers. Ultrasonic testing using the described tools allows detecting defects in radius zones up to 6 mm in size.
