Which statement describes a flex-type borescope?

• A. Has a flexible probe that snakes around in hard-to-reach areas and inspects areas without opening the engine
• B. Is limited to external viewing only
• C. Must be used with engine disassembly
• D. Has no illumination capability

Answer: (A)

A flex-type borescope is defined by its flexible insertion probe that can bend and twist to reach around obstacles in tight or hard-to-access areas, allowing you to inspect internal engine components without fully opening or disassembling the engine. This flexibility is what makes it possible to scope pistons, valve seats, and other internal surfaces through small access ports, often while the engine remains largely assembled. The tool is typically illuminated so you can clearly see the area you’re inspecting. This is why the statement about a flexible probe that snakes around in hard-to-reach areas and inspects areas without opening the engine is the best description. External viewing only would miss internal inspection capability, and requiring disassembly or lacking illumination would contradict how a borescope is used for confined-space inspection.
