Borescope Reviews: Aviation Engine Inspection Specialists
Borescope inspections are a critical part of our engine repair assessment process, enabling early identification of internal defects or concerns before an aircraft engine's purchase, lease transition, or end-of-lease period. At Fierbois Engine Services, we provide both on-site witness representation and desktop gas-path reviews throughout the UK and Ireland. Our aviation professionals guarantee every physical inspection assessment is meticulously documented and visual evidence is captured as needed for transparency and trust.
Our borescope check process involves:
- Conducting a detailed internal visual inspection of turbine and compressor sections using advanced borescope equipment.
- Witnessing and representing your interests during the inspection, ensuring nothing is overlooked.
- Documenting findings thoroughly, supported by high-resolution images and video if required.
- Delivering a clear summary report on any airworthiness issues or hardware defects that could affect the value, safety, or on-wing time of the engine.
- Offering actionable recommendations about the suitability of the engine for purchase or continued operation.
Our independent, mobile engine inspection services travel to your facility as needed, making us the go-to partner for aircraft engine support across UK and Ireland. By entrusting Fierbois Engine Services with your borescope reviews, you gain unbiased expert guidance, helping you avoid costly mistakes and maintain compliance with all FAA and EASA standards.
Performance Assessment: Post-Lease and On-Wing Aircraft Analysis
Even engines with seemingly flawless records can present hidden issues at the end of a lease. At Fierbois Engine Services, our engine repair assessment includes a thorough analysis of engine on-wing performance, so leasing companies and airlines can verify the asset's true condition before lease returns or purchases.
We use recognised health monitoring methodologies to assess power assurance test data, test cell analysis, and on-wing trend monitoring, ensuring a reliable picture of engine performance, durability, and expected remaining service life. Our findings give clients clarity about future reliability, helping inform crucial investment and operational decisions.
Thanks to our extensive experience in inspecting major engine types such as V2500-A5, CFM56 series, PW4000, Trent 700, Trent 800, and GE90 series, clients across the UK and Ireland rely on us for detailed, accurate, and unbiased aircraft engine support.
Witnessing and Overseeing: What We Supervise During a Physical Inspection Assessment
