Which tool is typically used for conducting a borescope inspection?

• A. A standard screwdriver
• B. A specialized camera device
• C. A multimeter
• D. A torque wrench

Answer: (B)

A borescope inspection is utilized to examine areas that are difficult to access, such as the internal components of an aircraft engine or other mechanical systems. The correct tool for this inspection is a specialized camera device. This tool is designed to capture images or video of the inspected area, allowing technicians to analyze the condition of the parts without needing to disassemble them.

The specialized camera often comes equipped with an eyepiece or a screen, and sometimes features adjustable illumination and various lens options to facilitate clear imaging in tight or dimly lit spaces. This capability is crucial for detecting issues such as corrosion, wear, or cracks that may otherwise go unnoticed, thus ensuring the safety and reliability of the powerplant.

The other tools listed are not suitable for conducting a borescope inspection. A standard screwdriver is a general tool for fastening and removing screws and cannot provide visual insight into internal components. A multimeter is used for measuring electrical parameters such as voltage and current, which is unrelated to visual inspections. A torque wrench is specifically designed for applying a specific torque to fasteners and does not perform any visual inspection or internal analysis.
