Which item is included with an assembly drawing to identify components?

• A. Ignition wiring diagram.
• B. Maintenance schedule.
• C. Parts list.
• D. Weight and balance data.

Answer: (C)

An assembly drawing shows how parts come together and where each piece goes, so you can see the overall layout. To actually identify each component on that drawing, you need a parts list (often called a bill of materials). The parts list provides the exact component names, quantities, and part numbers, allowing you to match every item on the diagram to the real part and order replacements if needed.

The other items serve different roles: an ignition wiring diagram is about electrical connections and routing, not labeling components on an assembly; a maintenance schedule covers service intervals; weight and balance data relates to aircraft loading.
