In aerospace as in many other industries, nondestructive testing (NDT) is the final quality assessment, the final check of a part before it enters into service. Without a quality process and excellent technicians working diligently with a lot of integrity, the parts may just not be of the highest quality and fit for the job.
Enter here one way to ensure a quality inspection process is obtained and maintained: the Nadcap industry-managed NDT audit for aerospace. The Nadcap NDT audit is different than any other NDT audit; to begin with, because it is much more in-depth and looks at every part of the process including qualification/certification, process controls, calibration of equipment, system performance and actual testing of hardware. But that is a bit of a simplification, as to get to an audit many things have happened.
