Which ATA chapter is associated with Doors?

• A. Fuselage
• B. Doors
• C. Nacelles/Pylons
• D. Stabilizers

Answer: (B)

This question tests how ATA maintenance manuals organize information by system, with each major function given its own chapter. Doors is treated as a distinct system, so all procedures, diagrams, and troubleshooting related to door operation, latching, actuators, seals, and emergency exit mechanisms are collected in the Doors chapter. This separation makes it quick to locate door-specific information without wading through other areas. The other options point to different systems—fuselage covers the airframe structure, nacelles/pylons the engine nacelles and pylons, stabilizers the tailplane assemblies—so they belong in their respective chapters, not the doors chapter. In many manuals, the Doors chapter is identified as Chapter 52.
