What is the minimum hours of task-specific NDI training for the first aeronautical part or structural feature?

The minimum hours of task-specific Non-Destructive Inspection (NDI) training for the first aeronautical part or structural feature is established at four hours. This duration is important as it ensures that personnel gain an adequate understanding of the specific techniques, safety procedures, and inspection criteria related to the NDI methods applicable to aeronautical structures. This training duration is designed to equip individuals effectively with the foundational knowledge and skills necessary for performing inspections that are critical for maintaining the structural integrity and safety of aircraft. Proper training in NDI is essential not only for compliance with safety standards but also for the overall reliability of the aircraft structures being inspected.
