Disclosed herein is an apparatus for ultrasonic inspection. The apparatus comprises, in certain examples, a base, a lower coupler block slidably coupled to the base such that the base is translationally movable relative to the lower coupler block, and a pair of wings rotatably coupled to the lower coupler block at a wing pivot point and pivotable between a first angle and a second angle. In certain examples, the apparatus also includes a sensor carriage located within the base and slidably coupled to the base such that the sensor carriage is translationally movable relative to the base.
