Engine Borescope Inspection (BSI) and Boroblending Services

Borescope Inspection (BSI)

A borescope inspection (BSI) is a non‑invasive procedure widely used in borescope inspection aviation to monitor engine health without requiring disassembly. Using a high‑resolution borescope with a camera at the tip, our team performs precise aircraft borescope inspection to detect issues early and verify the condition of internal engine components.

With more than 500 engine borescope inspections completed worldwide, our specialists also interpret inspection findings to accurately assess engine condition. This ensures your engines remain operational with minimal downtime and that every borescope inspection of aircraft engines yields clear, actionable results.

Whether it’s a pre‑repair, post‑repair, pre‑purchase, or on‑request inspection, our experts handle every aviation borescope inspection with care and precision. Contact us if your CFM56, V2500, PW100, LEAP, or CF34 engine, or 131-9/APS3200 APU, requires a video or standard engine BSI.

Boroblending

Boroblending is an engine compressor repair technique used for the CFM56 family and other engine types. This cost‑effective method restores engine blades when damage such as missing tip corners, cracks, dents, nicks, or tears is detected. Using specialised grinding and polishing techniques, boroblending allows for precise blade repair while maintaining overall structural integrity.

In many cases, the engine doesn’t need to be removed from the aircraft. Instead of grounding the aircraft for a week and sending the engine to a workshop, boroblending can be performed on‑wing in just a few hours, significantly reducing cost and operational disruption.

Frequently Asked Questions (FAQ)

An aircraft engine borescope inspection (BSI) is a non-invasive method for examining internal engine components without disassembling the engine. A borescope with an integrated camera is used to assess the condition of specific engine sections.

A borescope inspection can detect cracks, dents, nicks, tears, missing material, and other signs of wear or damage on internal engine components.

Borescope inspections may be performed as part of scheduled maintenance, troubleshooting, pre-purchase evaluations, pre-repair and post-repair activities, or on request.

A borescope inspection report typically includes inspection findings, images or video records, component condition assessments, and recommendations based on the observed results.

Borescope inspections allow internal engine components to be evaluated without disassembling the engine. This can reduce ground time for evaluation and support condition-based maintenance decisions.

Boroblending is a compressor blade repair technique used to address damage such as nicks, dents, cracks, tears, or missing tip material. It is performed when the damage falls within the applicable repair limits and procedures, and may avoid the requirement for an engine to be inducted into the workshop

Yes. A borescope inspection can identify certain conditions that may be addressed through on-wing maintenance or repair procedures, avoiding unnecessary engine removal. Repeat BSI inspection can also delay shop visits when within limits, and according to applicable instructions

A borescope inspection is performed using specialised camera tooling and does not require disassembly or removal of the engine, whereas a teardown inspection requires full engine disassembly to examine internal components directly in a workshop environment.

Borescope inspections are used to assess the condition of CFM56 engine components and support maintenance planning, troubleshooting, and repair decisions without full engine disassembly.

BSI is performed by qualified personnel in accordance with the applicable maintenance procedures, approvals, and engine manufacturer requirements.
