How would you rate your knowledge of the ATA codes?

As a certified Aircraft Mechanic, you need to at least have some working knowledge of the Air Transport Association Chapters, or system codes. Confirm to your interviewer that you have knowledge of what the codes are and what the overall significance of the codes mean in your work as an Aircraft Mechanic. Then, talk about the specific codes that you have firsthand knowledge with, through the work you've done in the past. As you answer, it doesn't hurt to mention that you enjoy learning more and more of the codes as your career progresses.
