A phased array transducer for inspecting a fastener hole and adjacent structure to identify defects and determine hole integrity without removing the fastener from the hole. The phased array transducer includes a plurality of transducer elements, where one of the transducer elements is used to align the transducer to the hole, one group of the remaining transducer elements inspects the entire thickness of the structure at one side of the fastener and another group of the remaining transducer elements inspects the entire thickness of the structure at an opposite side of the fastener.
