How often must NDI technicians perform radiographic image x-ray inspections to maintain X-ray proficiency?

NDI technicians are required to perform radiographic image x-ray inspections regularly to maintain their proficiency. Performing these inspections twice a month ensures that technicians remain skilled in interpreting and analyzing the x-ray images and that they stay familiar with the equipment and its operation. This frequency provides sufficient practice to retain critical skills and knowledge, enhancing the reliability and accuracy of their inspections in a professional setting.

While maintaining proficiency is essential, it doesn't necessitate excessive practice that might lead to diminishing returns. The choice of two times a month strikes a balance, allowing technicians to stay proficient without overwhelming them. This practice standard is set to ensure that they can consistently meet the demands of their roles and uphold safety and quality standards in aviation structural maintenance.
