In the aviation industry, non-destructive testing (NDT) techniques play an essential role in minimizing costs and keeping people safe.
Safety is important in every industry, but especially so in aviation, as one minor flaw or mistake can lead to tragedy. Aerospace components made with imperfections can result in tragic incidents. This risks the well-being and lives of people, in addition to significant amounts of money. Raw materials and components should be analyzed for safety and dependability by using an assorted set of inspections across all stages of production and maintenance.
NDT techniques are a critical group of these evaluation methods used during the production, construction, and maintenance of raw materials and parts – all of which demand thorough analyses that can detect any defects in a test subject.
NDT techniques also serve as a quality assurance measure used in the evaluation and certification of aircraft parts. Flaws or inconsistencies that are overlooked during production processes can result in costly repairs and part replacements that eat away at a company’s finances. The cost is increased much more if serious damage occurs, to the point a part or an entire aircraft section must be thrown away.
During scheduled maintenance, NDT techniques can also be employed to recognize flaws and the effects of wear. Problems can then be dealt with promptly as they show up. However, resolving an issue once does not guarantee that it will not reappear down the road.
With all of this in mind, the following non-destructive techniques are commonly used in the aviation industry.
Visual inspection by a properly trained individual can reveal cracks, leaks, and rust, and is one of the most frequently used NDT techniques. Most visual inspection is done with equipment such as a magnifying lens, special lighting, borescope, video camera and/or magnifying mirror. This NDT technique
