Which inspection is most comprehensive requiring disassembly and overhaul?

• A. Overhaul inspection
• B. Annual inspection
• C. Functional test
• D. Partial inspection

Answer: (A)

The most comprehensive inspection is the one that requires taking the equipment apart—disassembly and overhaul. When you disassemble, you can inspect every component for wear, corrosion, misalignment, or hidden damage that surface checks can miss. Components are cleaned, refurbished, or replaced as needed, then the system is reassembled and tested to ensure it’s restored to proper working condition. Other inspections, like annual checks or functional tests, assess condition or operation without tearing the unit down, so they don’t reach the same depth of inspection. A partial inspection targets only specific parts, not the entire system. So the overhaul inspection stands out as the one that includes disassembly and a full rebuild.
