An inspection apparatus and method for inspecting an interior surface of a hollow composite part. The inspection apparatus may have a first plug, a second plug, and a trolley positioned between the first and second plugs. The first and second plugs may form a leak-proof seal against the interior surface of the hollow composite part. The trolley may support at least one inspection probe for testing the interior surface of the composite part. A method of inspecting the composite part may include the steps of inserting the inspection apparatus into the hollow composite part, pushing or pulling the inspection apparatus with an elongated actuation element to a desired area to be inspected within the composite part, then filling a space between first and second plugs with a liquid. Finally, the method may include a step of inspecting the interior surface of the hollow composite part with the inspection probe. |

1. An inspection apparatus comprising:
a first plug configured for fitting within a hollow composite part and forming a leak-proof seal against an interior surface of the hollow composite part; a second plug configured for fitting within the hollow composite part, forming a leak-proof seal against the interior surface of the hollow composite part, and spaced a distance apart from the first plug; a trolley configured to be positioned between the first plug and the second plug, independently moveable relative to the first and second plugs in a direction toward and away from the first and second plugs, and configured to support at least one inspection probe for testing an interior of a composite part; and a cable, rod, or tube fixed relative to the trolley and fixed to or extending through at least one of the first and second plugs, wherein the cable, rod, or tube is configured to pull or push at least one of the trolley and the first and second plugs within the composite part. |
