6 Inspection Camera Accessories You Should Know About

A borescope is a vital tool used in aircraft inspections to assess and maintain the condition of various components such as aircraft engines, combustion chambers, turbine blades, and landing gear, among others. It is a visual inspection device that consists of a flexible probe with a tiny camera and light source at its tip. Borescopes are commonly used in the aviation industry for routine inspection of aircraft engines, as well as for identifying mechanical fatigue, thermal cycling, foreign object damage, and other potential issues that could lead to larger problems if left undiscovered. These portable and easy-to-use devices allow aircraft inspection professionals, as well as aircraft owners, to capture high-quality images and videos inside hard-to-reach spaces, enabling them to detect any hidden defects and make informed maintenance decisions. Borescopes are particularly useful in aviation maintenance inspections as they can provide enhanced lighting and access to confined areas, helping to ensure the safety, efficiency, and performance of aircraft.

Benefits of Using Borescopes in Aircraft Inspections

Borescopes play a crucial role in optimizing aircraft inspections and maintenance. By using borescopes, aircraft owners and inspection professionals can benefit in numerous ways.

First and foremost, borescopes save valuable time during inspections. Instead of disassembling various components, borescopes allow for non-destructive visual inspections. By inserting a probe with a built-in light source into the engine or other hard-to-reach areas, defects, debris, and imperfections can be quickly identified. This saves both time and resources, as disassembly and reassembly can be time-consuming and costly.

Additionally, borescopes help overcome several challenges in aircraft inspections. Cracks in engine components, such as turbine blades or compressor blades, can be accurately detected using borescopes. Debris particle accumulation in critical areas, like the combustion chamber, can also be easily identified, ensuring the smooth operation and longevity of the aircraft engine.

To cater to different aircraft inspections, various types of aviation borescopes are available. These borescopes come in different probe diameters and lengths to meet the specific inspection requirements of different aircraft components. Whether it is inspecting turbine sections, landing gear, or even helicopter engines, there is a borescope suitable for the task.

As shown, utilizing borescopes in aircraft inspections brings immense benefits. Saving time by allowing for non-destructive inspections, quickly identifying defects and debris, and overcoming challenges like engine cracks and debris accumulation are just a few reasons why borescopes are an essential tool for aviation inspection professionals and aircraft owners.

Types of Aircraft Inspections


Aircraft inspections are an essential part of ensuring the safety and functionality of aircraft. Several types of inspections are performed regularly to identify and address any potential issues.

Routine inspections, also known as scheduled inspections, are conducted at specific intervals set by the aircraft manufacturer or regulatory authorities. These inspections aim to assess the overall condition of the aircraft and its components, ensuring compliance with regulations and maintenance standards. Routine inspections may include visual inspections, as well as comprehensive checks of systems and structures.

In addition to routine inspections, there are also special inspections that are performed in response to specific events or conditions. For example, an aircraft may undergo an inspection following a hard landing, bird strike, or lightning strike. These inspections focus on assessing any potential damage or stress to the aircraft as a result of the specific event.

Furthermore, there are also pre-flight inspections, which are conducted by pilots before each flight. These inspections include a visual check of the exterior and interior of the aircraft, as well as a verification of the aircraft’s systems and controls. Pre-flight inspections are crucial for ensuring the aircraft is in a safe and airworthy condition before taking off.

Overall, the different types of aircraft inspections play a vital role in maintaining the safety and reliability of aircraft, helping to prevent accidents and ensure the continued operation of the aviation industry.

Routine Inspection

Routine inspections are an integral part of aviation safety, ensuring that an aircraft is in optimal condition before takeoff. These inspections are conducted by pilots and involve a comprehensive check of the aircraft’s exterior, control surfaces, and fuel system.

During a routine inspection, technicians closely examine the aircraft’s exterior for any signs of damage, such as dents, scratches, or loose panels. Control surfaces, including the ailerons, elevators, and rudder, are checked to ensure they are properly connected and functioning correctly. The fuel system is also carefully inspected for leaks, proper fuel quantity, and the correct fuel type.

Aircraft inspection professionals thoroughly examine various components of the aircraft to ensure its safety and airworthiness. One crucial area inspected is the landing gear. Inspection of the landing gear involves checking for any signs of wear or damage, such as cracks, corrosion, or loose bolts. The tires and brakes are also inspected to ensure they are in good condition and functional.

Another critical area inspected is the aircraft’s engines. Engine inspections involve a thorough examination of various components, including the combustion chamber, turbine blades, and compressor blades. Borescopes are often used to inspect these hard-to-reach areas, allowing inspection professionals to detect any signs of damage or wear that may impact engine performance.

Aircraft inspection professionals may encounter challenges during ground inspections, such as debris particle accumulation or foreign object damage. Accumulated debris, such as dirt or loose fittings, can hinder the functioning of various components. Foreign object damage, caused by objects like tools or loose parts, can also lead to significant safety issues if not detected and addressed promptly.

Overall, a thorough ground inspection is essential for maintaining the safety and airworthiness of the aircraft. By carefully examining and addressing any issues during these inspections, aircraft owners and inspection professionals can ensure the aircraft is in optimal condition for flight.
