Which statement describes a rigid borescope assembly?

• A. Allows for inspection of internal engine conditions
• B. Cannot be used for engine inspection
• C. Is used only for external surface inspection
• D. Requires disassembly for inspection

Answer: (A)

Rigid borescope assemblies are fixed, straight optical tubes that you insert through a small access port to look inside an engine. Because the tube is rigid, you get a direct, high-quality view along a straight path, making them ideal for inspecting internal components such as cylinders, valve seats, and interior surfaces for wear, cracks, or deposits. So, describing a rigid borescope assembly fits the idea that it enables inspection of internal engine conditions. It’s not limited to external surface checks, and while gaining access may require some removal of components or panels, the primary function is internal visualization rather than exterior inspection or mandatory full disassembly.
