What is an engine borescope?

An engine borescope is a specialized inspection tool used to visually examine the internal components of an engine without disassembly. It consists of a flexible or rigid tube with a camera and light at the end, which transmits images to a display screen. Technicians use borescopes to inspect for wear, corrosion, cracks, or foreign objects inside engines, helping to diagnose issues and plan maintenance. This non-invasive method saves time and reduces the risk of damaging engine parts during inspection.
