Airplanes generate profit only when they're in the sky, but in order to keep flying safely these metal birds need to be constantly checked and inspected. One of the most popular inspection techniques in the industry is non-destructive testing, also known as NDT.

Non Destructive Testing (NDT) is done to detect flaws in a product. In the field of aerospace, NDT plays a major role. In aviation an aircraft is tested for damages to determine the airworthiness of an aircraft. These damages needs to be... detected and reported if any, for obtaining flight clearance. NDT comprises a broad range of methods used to evaluate the properties of a component without disassembling it.
The damage is then categorised based on the level of damage and further action is taken if required. Aircraft surface inspection is carried out to observe damages on the surface region of an aircraft. Earlier maintenance crews used pit gauge to measure the size of damage.
With advancements in technologies software assist the maintenance crew to carry out their work with ultimate precision and accuracy. With modern tools such as SmartDENT3D, a technician or investigator needs to scan the aircraft’s surface with a hand held scanner. The surface is examined for irregularities or dents. The n these scanned inputs are analysed using the inspection software and defects are visualised as results, providing the exact location and details of the defect (size, type of defect etc).

By adopting this technology, the job is performed 80 times faster than while using pit gauge technique. This in-turn ensures the airworthiness of an aircraft.
