Which set of systems falls under the maintenance responsibilities of the Accessories Flight?

• A. Propulsion and navigation systems.
• B. Avionics and communication systems.
• C. Structural and airframe systems.
• D. Electrical and Environmental systems, egress systems, fuel systems, and hydraulic systems.

Answer: (D)

Accessories Flight handles the auxiliary systems that support aircraft operation, not the core flight propulsion, avionics, or airframe structures. The group that fits this scope includes Electrical and Environmental systems (power generation, wiring, climate control), Egress systems (canopy and emergency exit components), Fuel systems (fuel pumps, lines, and storage components), and Hydraulic systems (pumps, actuators, and fluid lines). These are all ancillary subsystems essential to flight but separate from propulsion, navigation/avionics, or structural airframe work, which are managed by other maintenance flights. Hence this set is the best match for what the Accessories Flight maintains.
