Why choose Addison for Expert Technical & Flightline Support?
Beyond our workshop, Addison Avionics serves as a trusted partner to maintenance crews and operators around the world. We offer expert technical support to help you troubleshoot complex issues and make informed decisions. Our dedicated team of experts leverages extensive technical experience and a deep understanding of aircraft systems to provide the guidance you need, when you need it, helping you to isolate faults efficiently and reduce unnecessary maintenance costs.


Key Features of Our Technical Support Service
Our support extends far beyond the avionics we repair in our shop. We have dedicated experts with deep knowledge in a wide range of aircraft systems, including landing gear, engines, airframes, and complex avionics and electrical issues. This holistic understanding allows us to help you diagnose problems more effectively, understanding how different systems interact.
Before you remove a component, a quick call to our support team can save valuable time and resources. We can walk your maintenance crew through diagnostic steps to help isolate a fault, potentially identifying a simple issue like wiring or a sensor problem, thereby preventing the unnecessary removal and shipment of a perfectly functional avionics unit.
We provide direct, hands-on flightline support for aircraft maintenance facilities and FBO operators. Whether it’s assisting with a complex avionics squawk on the ramp or providing expert backup for your maintenance team, we can be your partner on the ground to ensure problems are resolved efficiently.
