What is a Borescope Inspection?

A borescope inspection is a type of inspection that uses a borescope tool to visually inspect areas of the aircraft and engine that are not easily accessible. Performing borescope inspections allow maintenance workers to check the overall condition of the engine or turbine which helps prevent accidents caused by engine failure and avoid costly maintenance repairs.

Things to Look out for During a Borescope Inspection

In any industry, inspections play a big role when it comes to maintenance. Borescope inspections allow aircraft maintenance workers to thoroughly inspect aircraft engines and identify issues before they get out of hand. Below are six major things aircraft maintenance workers should look out for when conducting a borescope inspection:

  • Worn-out components
    Engines may be long-lived, but they’re still prone to wear. Components need to be replaced from time to time to ensure that they work according to their intended use.
  • Poor lubrication
    Components of the aircraft engine need proper lubrication to function properly. Keep in mind the appropriate volume, and the right type of lubricant for each component. Observing proper lubrication maintenance routine protects your equipment from engine oil burning and other damages.
  • Contaminated fluids
    Aircraft engines are built to keep dirt and debris out of the fluids. Should the engine oil, become contaminated the source of contamination should be tracked down and then corrected. Examples of engine oil contaminants are abrasives (dust and dirt), water, coolant, and unburned diesel fuel. When contamination occurs, the fluids need to be flushed and replaced to prevent further damage.
  • Leaks
    During the inspection, keep an eye out for implications of leaks. Leaks not only let out fluids your airplane engine needs to operate, but it can also let in contaminants that can sabotage the performance of your airplane engine fluids.
  • Cracks
    A cracked engine component indicates a severe engine problem. When cracks are found within the components of the engine, that part becomes brittle which then escalates to larger issues such as loss of fluids and overheating.
  • Corrosion
    Internal engine components should not rust and corrode over time, which means that in the event that you find corrosion, this indicated that there is an area within the engine that shouldn’t be getting water and air in the first place.

Borescope Inspection Best Practices

Borescope devices for inspections have become essential tools of the trade in the aviation industry. Periodic inspection and regular maintenance is required to not only prolong the life of the engine but also ensure its safety for use. Make your borescope inspections more effective with the following good practices:

Be familiar with your equipment.

It is always important to know your equipment before using it. Without proper knowledge on the equipment, you risk yourself human error that you may not even know how to correct. Familiarize yourself on how to operate the borescope tool. Take advantage of training and learn about its limitations.

Have a clear understanding of equipment standards.

Another important thing to consider during borescope inspections is being knowledgeable with the items you are inspecting. Inspectors should have a clear understanding of what a good and part looks like and be aware of defects to look out for.

Prepare a good inspection report.

The quality of an inspection report represents the quality of the inspection work, which is why borescope inspection reports should be properly documented, accurate and comprehensive. A good borescope inspection report should contain basic information such as, damage description. It should describe the general appearance of the defect and determine defect category such as ablation, nick, dent, etc. Features of the defect such as measurements and dimensions should also be provided, to clearly understand the overall situation and provide an accurate judgement.

What is iAuditor and How Can It Help Borescope Inspections?

Approximately 90% of aircraft maintenance inspections are visual, which makes it vital that a borescope inspection be performed effectively, efficiently, and consistently. Solve and avoid critical issues with iAuditor and create comprehensive inspection reports.

With iAuditor, inspections are just the beginning. Equip your maintenance team with a mobile inspection tool that lets you do the following:

  • Conduct borescope inspections using beautiful inspection templates you can create in minutes or use and customize an existing one from the public library.
  • Take or attach photo evidences from borescope device on your borescope inspection template and add in appropriate annotations and comments.
  • Escalate issues identified during the inspection with collaborative actions. Assign a team member, set priority and due date.
  • Generate comprehensive reports that you can easily share across multiple recipients in the organization.
  • Keep all your reports secure in one place. Inspection reports are saved and secured in your account for you to access whenever you need them.
