Which ATA chapter covers Nacelles/Pylons?

• A. Cargo and Accessory Compartments
• B. Fuselage
• C. Airborne Auxiliary Power
• D. Nacelles/Pylons

Answer: (D)

Understanding how ATA chapters are organized helps you quickly find maintenance information by system. Engine nacelles and pylons are the dedicated subject of the Nacelles/Pylons chapter, which covers the nacelle structure, engine mounting to the wing, thrust reversers, pylons, and the related components and procedures. When you’re working on or inspecting engines and their mounting hardware, this chapter is the go-to resource for drawings, inspection criteria, torque specs, and repair steps specific to that area. The other topics point to different chapters: cargo and accessory compartments pertain to the areas that hold cargo and the associated equipment, fuselage addresses the aircraft’s main body structure and its systems, and airborne auxiliary power deals with the aircraft’s auxiliary power unit and its related systems. Since the question asks which chapter covers Nacelles/Pylons, the proper match is the chapter dedicated to engine nacelles and pylons.
