Borescope Inspections of Aircraft Engines

Borescope Inspections

A borescope inspection is a full health check of the singularly most expensive component attached to your aircraft  – The Engine. This video inspection highlights the visible defects ensuring your asset is in a condition worthy of sale or purchase, lease or continued service.

Much of our work in this field is for Leasing Companies, Airlines and Maintenance Organisations performing pre-purchase, lease return and scheduled or non-scheduled maintenance inspections.

A borescope is the industrial version of the medical endoscope and is used in a similar way. That is to view or inspect something that is not easy to get to without taking apart or disassembly or major surgery in the case of the endoscope.

Another name for Borescope is Remote Visual Inspection or RVI for short. The “remote” refers to the fact that the operator’s eyes do not view the item directly, the item to be inspected is remote from the operator so the borescope is used to convey the visual image to the operator’s eyes. Borescopes are used in many different applications we use them to look inside the casing of jet engines to see the internal parts.


RVI Borescope Inspection Services

Our inspections fall into 3 main categories these being

  1. The routine time limited inspections, which ensure the safe continuation of the engine in service.
  2. The emergency, unexpected or unplanned situation such as a bird strike, volcanic ash ingestion or fault diagnosis of a badly running engine (surging or stalling).
  3. The full inspection is usually only called for when the engine is bought, sold or the lease changes.

The first 2 above focus on the serviceability and safety of the engine where item 3 is aimed at the commercial aspect before entering or re-entering into service, the cost of any repairs or the ability of the engine to remain in service for a certain time frame.

The first 2 types of inspection tend to take less to carry out but are often carried out outside and overnight the 3rd type should be planned and should be inside a suitable maintenance facility.

RVI Ltd will record all aspects of the inspection with the addition of images with measurements, if required, we then produce an in depth written report and DVD once back in the office.

At the completion of any inspection irrespective of inspection type RVI will issue the industry standard certificate a “Form 1” under our European and American approvals assuming the engine was serviceable with no defects outside the limits of the relevant manuals.

We will provide clients with an interactive DVD recording of the complete inspection, along with a detailed written report and digital images of any defects or damage found.

The video recording (DVD) of the inspection provides a comprehensive record of the health of the engine gas path at a fixed point in time.


Our Technology

RVI Ltd uses the latest and most advanced flexible video borescope equipment produced by Olympus Industrial.

We now own and use the latest Olympus Borescope System the IPLEX NX with advanced Digital Stereo measuring capability.

The IPLEX NX kit has a 3.5m scope, 6mm in diameter with full 4 way electronic articulation. The light is produced by a laser within the kit body and the image is picked up by the video chip mounted in the tip under the lens adaptors. This kit is capable of very accurate measurement using a stereo system. The video clips are recorded in hi-definition video.

Why use RVI for your aircraft engine borescope inspection?

Our main asset is our impartiality, we are totally independent and are not swayed by the commercial pressures to “keep the engine on wing at all costs” or equally “pull the engine and pass on the costs!!”.

RVI performs all inspections as per the client’s instructions but always strictly in accordance with the aircraft’s current maintenance manual or in certain cases the current engine manufactures maintenance/overhaul manual.

We will assess all defects and make recommendations with regard to serviceability and if required will liaise with the engine manufacturer’s local representative on behalf of the client (you).

We are leading the industry in respect of the equipment used, inspection techniques and DVD reporting. RVI Ltd have a capability that leading airlines and maintenance facilities yearn for.
