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. 1. A phased array transducer for inspecting a fastener hole and adjacent structure without removing a fastener from the hole , said transducer comprising:a body including a upper body portion and a lower body portion; anda plurality of transducer elements positioned in the body, wherein at least one of the transducer elements is a centering transducer element that locates the center of the hole or fastener, said plurality of transducer elements also including two groups of inspection transducer elements, where a first group of the inspection transducer elements inspects one side of the hole and a second group of the inspection transducer elements inspects an opposite side of the hole.2. The transducer according to wherein the body includes a semi-circular cut-out section configured to accept a portion of the fastener.3. The transducer according to wherein the lower body portion is made of a clear or translucent plastic.4. The transducer according to wherein the body is rectangular.5. The transducer according to wherein the plurality of inspection transducer elements is thirty-two transducer elements claim 1 , where the first group of inspection transducer elements is sixteen elements and the second group of inspection transducer elements is sixteen elements.6. The transducer according to further comprising a magnet positioned in the lower body portion.7. The transducer according to ...
