Definition
An engineering drawing that shows a single part in full, with all the dimensions, tolerances, materials, finishes, and notes needed to manufacture or inspect that part on its own.
Plain English
A drawing of one specific part by itself, with everything you need to know to actually make it or check it.
Context Anchor
Seen in aircraft maintenance, repair, manufacturing, and parts documentation when a specific part must be made, checked, or replaced.
Derivation
From the French détail, meaning a small piece cut from a whole. A detail drawing zooms in on one piece of an aircraft and shows it on its own, separate from the larger assembly.
Why Pilots Care
Ensures every replacement part meets the exact standards needed for safe flight.
Analogy
A detail drawing is like a recipe card for one part. It does not show the whole meal; it tells you exactly how that one item must be made.
Intuition Check
Do not read detail drawing as just a drawing with lots of detail. In this context, it means a drawing for one specific part, not the whole assembly.
Example Sentence 1
The mechanic pulled the detail drawing of the bracket from the structural repair manual to verify the hole spacing before drilling.
Example Sentence 2
Each rivet hole location was verified against the detail drawing supplied by the manufacturer.
