FAA Aviation Mechanic General (AMG)Aircraft Drawings, Weight and BalanceMedium
A technician needs to see how the individual detail parts of a landing gear actuator fit together, including part numbers, quantities, and their relative positions, but does not need the detailed dimensions of each individual part. Which type of drawing should the technician consult?
- ABill of materials
- BDetail drawing
- CSectional view
- DAssembly drawing
Show answer & explanationAnswer & explanation
Correct answer: D. Assembly drawing
An assembly drawing shows how multiple detail parts fit together as a complete unit, typically including item numbers, part numbers, and quantities referenced to a parts list, without giving full dimensions of each individual part.
Why the other options are wrong
- A. A bill of materials is a text list of parts and quantities, not a pictorial drawing.
- B. A detail drawing fully dimensions a single individual part, not the assembly relationship.
- C. A sectional view shows internal detail of one component, not overall assembly relationships.
Assembly Drawing
A drawing that shows how detail parts are put together to form a complete unit, typically with item/part numbers and quantities keyed to an accompanying parts list.
- Shows relative position of multiple parts
- References part numbers/quantities, not full dimensions
- Often paired with a bill of materials
Memory trick: Assembly = 'Assemble the puzzle' — see how pieces go together.
