A shear wave inspection tool has a housing with a rotatable top removably fixable over a fastener hole in a structure. An aperture is positioned through the rotatable top and operable to couple an ultrasonic transducer such that when rotatable top is rotated, the ultrasonic transducer transmits a shear wave into the structure around the fastener hole inspecting the fastener hole for an anomaly. A shear wave inspection system includes the inspection tool, an ultrasonic transducer, an ultrasonic data instrument operable to acquire data from the ultrasonic transducer, the nature of the received data indicates the presence of an anomaly in the fastener hole. A method for detecting anomalies in a fastener hole includes removably fixing the inspection tool over a fastener hole and rotating the rotatable top such that the ultrasonic transducer transmits a shear wave in a controlled sweep around the fastener hole.

Apparatus and method for ultrasonic shear wave inspection

In accordance with one or more aspects of the present disclosure, an apparatus for inspecting a part having a non-linear cross section includes a stationary sensor element including at least one phased array sensing unit, each of the at least one phased array sensing unit having a shape that is geometrically complimentary to the non-linear cross section of the part, and a support for the part having the non-linear cross section, the support comprising a drive assembly configured to move the part relative to the stationary sensor element, through an inspection beam emitted from the at least one phased array sensing unit.
