Avionics

ATA · 5508 parts

Avionics are the electronic systems that handle communication, navigation, monitoring, and flight management in an aircraft — from panel-mounted radios and transponders to GPS navigators, audio panels, and engine instruments. This category covers avionics units and related hardware for general-aviation aircraft, including equipment from manufacturers such as Garmin, BendixKing, and Icom. Every purchase here is self-serve from start to finish. Use the search bar if you already know the part number, or browse the listings below to compare units by price and availability. If you are not sure whether a unit fits your aircraft, the Aircraft Finder matches parts to your specific make and model using FAA aircraft data, so you can confirm fitment before you buy — no phone calls and no quote requests. Documentation matters in avionics. Where available, eligible items include FAA Form 8130-3 airworthiness documentation; check the individual product listing for the paperwork supplied with each unit. Listings also show condition, so you can tell at a glance whether a unit is new, overhauled, or serviceable.
