Which ATA chapter number corresponds to Wings?

Which ATA chapter number corresponds to Wings?

• A. ATA 56
• B. ATA 61
• C. ATA 70
• D. ATA 57

Answer: (D)

ATA chapters group information by aircraft system, so each major area has its own chapter. Wings is treated as its own subsystem and has a dedicated chapter that collects all wing-related data—structure, components, and related systems—in one place. That makes it the best reference when you’re looking up anything about wings, rather than data for other subsystems like fuel or engines. The other options point to different parts of the aircraft, so they don’t fit when the topic is wings.
