Which ATA chapter covers Lights?

Which ATA chapter covers Lights?

• A. ATA 25 Equipment / Furnishings
• B. ATA 29 Hydraulic Power
• C. ATA 33 Lights
• D. ATA 34 Navigation

Answer: (C)

Lighting systems, interior and exterior, are organized under the Lighting chapter of the ATA specification. This chapter specifically covers all aspects of aircraft lighting, including cockpit illumination, instrument lights, panel lighting, exterior lights like landing and taxi lights, and beacon lights, along with the related maintenance data, inspection criteria, and troubleshooting steps. The reason this is the best fit is that the ATA system assigns each subsystem to a dedicated chapter, and lighting has its own chapter to keep all related information consistent and easy to locate. The other chapters address different areas: Equipment / Furnishings covers cabin equipment and furnishings, Hydraulic Power deals with hydraulic systems, and Navigation covers navigation-related systems. Since none of those focus on lighting, the Lighting chapter is the correct source for maintenance information on lights.
