Which level explicitly uses precise measurement equipment during inspection?

• A. GVI
• B. Detailed Inspection
• C. Overhaul
• D. MBCS

Answer: (B)

Precise measurements are used when you need to confirm that components stay within exact tolerances. In the Detailed Inspection phase, technicians employ calibrated measuring tools—such as gauges, micrometers, calipers, and other metrology equipment—to quantify wear, clearances, and deviations from specified limits. This explicit use of measurement devices to verify dimensions is what distinguishes Detailed Inspection from other levels, which rely more on visual checks or broader maintenance activities. General Visual Inspection focuses on obvious issues by sight or simple tools, while Overhaul and MBCS involve broader tasks or condition-based assessment that aren’t defined by precise metrology during the inspection itself.
