Borescope Use in Aviation

First, let’s answer “What is a Borescope?” A borescope – commonly referred to as video scopes and industrial endoscopes – are inspection cameras that are widely used in aviation and aeronautics industries to ensure that internal components are within optimal performance standards. Aviation specialists depend on aircraft borescopes as a visual inspection tool for fixed-wing aircraft, helicopters, and aircraft engines. 

How is a borescope used in Aviation?

To conduct thorough aviation maintenance inspections, the aircraft borescope tool of choice for most modern-day inspectors is a video borescope, also known as a videoscope. A video borescope provides onboard capabilities, such as image capture and video recordings, to keep detailed records and to document the inspection. These specialized borescopes are often equipped with enhanced lighting to illuminate the inspection area, by either external light sources or built-in LED lighting. 

Borescopes are mostly used in nondestructive testing techniques for identifying defects, debris, or imperfections. This means less time spent disassembling and reassembling key pieces of equipment. Borescopes are commonly used in the visual inspection of aircraft engines, wind turbines, industrial gas turbines, steam turbines, and automotive engines. Fast, non-destructive, and incredibly versatile, engine borescopes can provide much-needed insight into the condition of an aircraft. 

Aircraft inspection professionals face a number of challenges in their daily duties. Experts have to be on the lookout for even the tiniest of issues. Engine cracks, for instance, are commonly caused by thermal cycling. Unintended vibrations, overheating, and mechanical fatigue can all contribute to the issue. With the right engine videoscope, spotting these cracks is easier than ever. A flexible borescope can wind through even the tightest of spots.  

Debris particle accumulation is another challenge of aircraft inspection. Foreign object damage can lead to serious wear and tear, corrosion, and residue build-up. Borescope accessories, like LED lighting, can help identify these sorts of challenges, leading to easier resolution. 

Aircraft borescopes provide magnified images, recorded footage, and the best possible inside look into hard to reach areas. With a variety of lengths, probe diameters, and features available, borescopes prove instrumental to the modern aircraft inspection process.
