Semi-analytical solution of one eddy current testing problem is presented in the paper. A coil with alternating current is located above a conducting half-space with a flaw in the form of a circular cylinder. The axis of the coil coincides with the axis of the cylinder. The problem is solved by the method of truncated eigenfunction expansions. The change in impedance of the coil is computed for different values of the parameters of the problem.
