15 Years of Aircraft Wiring Harness Repair Expertise
For more than 15 years, GTSMRO has specialised in the repair and overhaul of aircraft electrical wiring harnesses, building extensive experience across commercial aviation, engine, APU and airframe applications.
Since being founded in 2010, aircraft wiring harness repair has been at the core of our MRO capability. Today, GTSMRO is trusted by airlines, engine overhaul facilities, MRO organisations and aviation companies worldwide to provide reliable, cost-effective repair solutions for critical aircraft electrical components.
Over 4,000 Aircraft Wiring Harnesses in 24 Months
Experience is not simply measured in years. It is built through the volume, variety and complexity of repairs completed.
In the last 24 months alone, our experienced technicians have repaired or overhauled more than 4,000 aircraft electrical wiring harnesses.
Throughout that period, we have maintained a warranty rate of just 0.58%, demonstrating the quality, reliability and consistency of our repair processes.
4,000+ harnesses repaired or overhauled. 24 months. 0.58% warranty rate.
These figures reflect the experience of our people and the standards applied to every component that passes through our facility.
Aircraft Wiring Harness Specialists
Unlike general component repair organisations, GTSMRO has developed specialist expertise in aircraft electrical wiring harnesses, cable assemblies and electrical looms.
Our team has extensive experience supporting wiring harnesses installed across:
- Aircraft engines
- Auxiliary Power Units (APUs)
- Nacelle systems
- Landing gear systems
- Other critical aircraft electrical applications
Our engine wiring harness experience covers major commercial engine platforms, including CFM56, LEAP, CF34, CF6, GE90 and GEnx, together with a wide range of associated electrical harnesses and cable assemblies.
This specialist focus gives our technicians an in-depth understanding of the construction, inspection, failure modes, repair techniques and testing requirements associated with aircraft wiring harnesses.
Comprehensive Aircraft Wiring Harness Repair Capability
Every aircraft wiring harness received by GTSMRO undergoes a controlled inspection and repair process using approved maintenance data and appropriate tooling.
Depending on the component and approved repair data, our capabilities include:
- Detailed visual and electrical inspection
- Connector inspection, repair and replacement
- Contact and terminal replacement
- Wire and cable repair
- Branch and breakout repairs
- Identification and sleeving replacement
- Harness reassembly
- Restoration and replacement of protective braiding
- Continuity testing
- Insulation resistance testing
- Dielectric testing
- Final inspection and certification
Our facility also includes in-house overbraiding capability, with multiple braiding machines allowing us to restore protective coverings using materials including stainless steel, nickel, PEEK and fibreglass.
Automated electrical harness testing provides further assurance through controlled continuity, insulation resistance and dielectric testing.
Experience That Helps Reduce Aircraft Maintenance Costs
Aircraft wiring harnesses operate in demanding environments where they can be exposed to heat, vibration, fluids, contamination and repeated maintenance activity.
Damage does not always mean that a harness needs to be replaced.
Where approved repair data permits, specialist repair and overhaul can restore an aircraft wiring harness to a serviceable condition, helping operators and MRO organisations reduce replacement costs, overcome OEM lead times and return components to service more quickly.
Our experience allows us to assess each harness individually and identify the most appropriate repair solution while maintaining the required airworthiness and quality standards.
Quality and Reliability at the Heart of Every Repair
Quality and reliability are at the heart of everything we do.
GTSMRO operates as an approved aviation maintenance organisation with UK CAA, EASA and FAA Part 145 approvals, supported by established quality and environmental management systems.
But approvals alone do not make an organisation an expert.
Our expertise comes from 15 years dedicated to aircraft electrical component repair, thousands of wiring harnesses processed, experienced aviation electrical technicians, specialist equipment and an ongoing commitment to developing our repair capability.
The result is a specialist aircraft wiring harness MRO capability trusted by customers throughout the global aviation industry.
