Abstract
A method and system for inspecting a turbine wheel having axial slots along a perimeter thereof that are configured for mating with and securing airfoil members to the perimeter of the wheel, and an annular slot that intersects the axial slots. The method and system make use of one or more eddy current probes that are placed in the annular slot to electromagnetically inspect the annular slot and at least one of the axial slots for cracks in surfaces thereof. The probe is part of a probe assembly that includes a mounting member for engaging at least one of the annular and axial slots. The probe assembly is operable to maintain the probe at a fixed distance from surfaces of the annular slot as the probe travels through the annular slot.
