What We Source
Avionics procurement is driven by part number specificity — the model, serial number, and software version all matter. We source from a network of MROs, avionics shops, and serviceable inventory pools globally.
Common procurement scenarios: panel retrofit projects (G1000 upgrade), ADS-B compliance mandates, autopilot system failures, and NTSB-required instrument replacements. Whether you need a Garmin GTN 750 or a vintage Bendix/King KX 155, we locate it.

Exchange vs. Surplus — What to Know
Exchange units come from core-traded inventory — you return your failed unit as a core exchange. This is the standard procurement model for panel-mount avionics and typically gets you a unit with known hours and test history.
Surplus units are serviceable pull-outs from aircraft upgrades or teardowns — no core return required. Surplus is often the right call when you need a quick turn and the aircraft is already down.
Certification
All avionics come with 8130-3 or equivalent from the issuing Part 145 facility. DO-178C software level documentation is available for software-driven systems (FMS, glass displays). PMA parts are identified where applicable.
