ATA - 105
Guidelines for Training and Qualifying Personnel in Nondestructive Testing Methods

ATA Spec 105 serves as a guideline for the development of a training program for personnel who accomplish nondestructive testing (NDT) tasks. While partially derived from more universal training standards, such as ASNT Recommended Practice No. SNT-TC-1A and NAS 410, this document describes an approach for preparing a curriculum for an airline's maintenance training program and for qualifying individuals to conduct aircraft inspections. Originally issued in 1990, the 2009.1 revision harmonizes several training requirements to NAS 410 requirements.
