Which item is NOT typically included in the drawing block of an aircraft part?

• A. Name of the draftsman.
• B. Scale of the drawing.
• C. Name of the engineer approving the part.
• D. Material composition.

Answer: (D)

The drawing block is focused on identification and accountability for the drawing itself. It includes who prepared the drawing (the draftsman), the scale used, and who approved it (the engineer), along with revision history and other administrative details. These elements are about traceability and ensuring the drawing can be accurately interpreted and verified.

Material composition, by contrast, is a specification detail about what the part is made from. That information belongs in the engineering specification or the bill of materials, not in the drawing block. It may be referenced elsewhere on the drawing as a note, but the formal material makeup is not part of the drawing block. So the item that isn’t typically included there is the material composition.
