Safety is of paramount importance in the Aviation industry and this is dependent on a growing worldwide maintenance, repair & overhaul (MRO) industry. Newly manufactured aircraft components also undergo rigorous inspection before they are assembled into the aircraft body itself. NDT procedures allow inspectors to test the integrity of parts and bonds, sometimes in areas of the plane that would otherwise be un-testable unless the structure was disassembled to gain access. Additionally damage that is too small to be visually detected can be found. NDT plays a vital role in keeping air travel one of the safest modes of transportation. New composite materials create new inspection challenges to the industry, and NDT is at the forefront of material quality control.
