The weekly reading assignments covered the various Destructive Testing (DT) and Non-Destructive Testing (NDT) techniques utilized during the design, fabrication, and in-service aircraft composite structures. We learned that these inspection techniques allow inspectors to evaluate composite structures' integrity at different stages of their lifetime. Without them, it will be challenging, or if not impossible, to achieve an accurate evaluation outcome to ensure airworthiness. Prepare a 10x10 PechaKucha style presentation identify the flaws/defects that can be accurately picked up with the choice of Ultrasonic Testing for sandwich composite component. Describe how the flaws and defects picked up by the inspection technique contribute to the Damage Tolerance Evaluation section in AC 20-107B for structural integrity.
