Definition
A thorough, close-up examination of a specific aircraft component, system, or area, typically performed with the aid of inspection tools, adequate lighting, surface cleaning, and sometimes partial disassembly to reveal hidden defects, wear, corrosion, or damage that would not be visible during a routine visual check.
Plain English
A careful, up-close inspection of a specific part of the aircraft, often using tools and good lighting, and sometimes taking things apart to see clearly. It goes much deeper than a quick look-over.
Context Anchor
Seen in aircraft maintenance manuals, inspection checklists, and work cards that tell a mechanic exactly how closely an area must be checked.
Derivation
From Latin 'detaliare' (to cut into pieces) via French 'détail' — meaning to look at something piece by piece. The word emphasises that the inspection examines each individual part rather than the whole at a glance.
Why Pilots Care
Detects hidden damage or wear that could lead to in-flight failure if left unaddressed.
Intuition Check
Do not read “detailed” as just “more careful than usual.” In maintenance, a detailed inspection is a specific level of inspection that may require cleaning, extra light, tools, and access to see the area properly.
Example Sentence 1
After the hard landing, the mechanic performed a detailed inspection of the landing gear attach points before returning the aircraft to service.
Example Sentence 2
A detailed inspection of the horizontal stabilizer is required following any lightning strike.
