ABSTRACT:
A method of detecting cracks and structural separations in the fuselage of an aircraft utilizes a highly detectable gas such as chlorofluorocarbon. The gas will be pumped into the interior of the fuselage until the fuselage reaches a pressure that occurs during normal flight operations. A detector will then be moved over the skin of the fuselage. The detector is of a type that will detect minute amounts of any gas escaping through cracks and structural separations in the fuselage. The detector has an entrapment shoe which entraps any gas that might be bleeding off through a tiny crack. The detector has an alarm circuit which provides an alarm to the operator.
