Why choose Addison for Wire Harness Repair & Manufacturing?
An aircraft’s wiring harness is its central nervous system, a complex component critical for safety and reliability. When a harness becomes damaged or fails, OEM replacements can be prohibitively expensive or have long lead times. Addison Avionics provides a specialized and cost-effective solution. We offer expert repair, rebuilding, and complete remanufacturing services for aircraft wiring harnesses, saving you thousands in the process while restoring the integrity of your aircraft’s electrical systems.


Key Features of Our Wire Harness Service
Our technicians can meticulously repair damaged sections of a harness, replacing individual wires, pins, and connectors to restore full functionality. For more extensive damage, we offer a complete rebuilding service. If you have a harness that needs to be rebuilt, we will use your existing harness as a template to construct a new, airworthy harness that perfectly matches the original’s form, fit, and function.
In cases where a harness is beyond repair or an OEM replacement is unavailable, we have the capability to completely remanufacture your wiring harness. This service is invaluable for operators of legacy or custom aircraft, providing a path forward where none may have existed before.
Our primary goal with this service is to provide a safe, high-quality alternative that can save you thousands compared to the cost of a new OEM harness. By choosing to repair or rebuild, you avoid the high price tag of a factory-new part without compromising on quality or airworthiness, making it a financially prudent decision for any operator.
