I. Knowledge of the ultrasonic-eddy current, and industrial x-ray radiographic methods of nondestructive testing to investigate failures in critical aircraft structures and components when considerable unknown factors are involved.
2. Knowledge of the various shapes, sizes, and density of flaw indications in parts being tested.
3. Knowledge of safety regulations and procedures.
4. Skill to set up and operate ultrasonic, eddy-current, and radiographic equipment to examine a variety of parts, components, or material to detect hidden subsurface flaws, corrosion and separation in bonded and honeycomb structures; integrity of welds; precision dimensional and volume measurements; hardness of materials; and to determine if defects found render the article acceptable or unacceptable.
5. Skill to work with quality assurance and engineering personnel to modify inspection procedures and test standards to achieve inspection objectives.
6. Ability to develop, modify, and adapt ultrasonic-eddy current, and industrial x-ray radiographic methods and techniques of nondestructive testing to investigate failures in critical aircraft structures and components when existing inspection procedures, techniques, and acceptability standards are non existent or not applicable.
7. Ability to read and interpret quality control directives, engineering drawings, NDl literature, and technical orders concerning nondestructive testing methods and procedures.
8. Ability to interpret flaw indications and their relevance to the reliability of products.
9. Ability to document actions and maintain records manually or on a computer terminal.
