ATA 83 covers which component area?

• A. Turbines (Reciprocating Engines)
• B. Exhaust
• C. Accessory Gearboxes
• D. Oil

Answer: (C)

Understanding how ATA chapters map to component areas helps you locate maintenance data quickly. ATA chapter 83 is the designation used for the Accessory Gearboxes on aircraft engines. The accessory gearbox is the drive that powers engine accessories such as the oil pump, fuel pump, hydraulic pump, generators, and the starting motor, and it includes related mountings, drive gear interactions, and lubrication interfaces. Maintenance procedures, installation notes, troubleshooting guidance, and diagrams for this gearbox are organized under this chapter, which is why it’s identified as the Accessory Gearboxes area. Exhaust and Oil belong to different ATA chapters that handle their respective systems, and the broader engine sections cover other engine-related items, not the gearbox specifically.
