This article highlights the importance of continuous flights and sustainable maintenance techniques to maintain competitiveness in the aviation industry. Structural components represent a significant portion of overall maintenance costs, and advanced nondestructive inspection techniques can help reduce maintenance time and associated costs. With the increasing use of composite structures in aircraft, it is essential to understand the possible types of defects that can occur and to use techniques the appropriate nondestructive techniques (NDT) for their identification and characterization. Comprehensive knowledge of possible defects and proper application of NDT techniques can help simplify maintenance operations and ensure sustainable and safe aircraft operations. The use of NDT techniques makes it possible to verify the quality of the composite material and identify any defects. This allows timely action to correct any problems and ensure maximum reliability and durability of the material. In this context, this paper provides a comparison of several techniques as nondestructive methods on a sample of interest to the aerospace industry and evaluates the parameters of their use: shearography, thermography and ultrasound.
