Autopilot South is a specialized division of Thom Duncan Avionics, an FAA Repair Station. We focus on the installation and integration of manufacturer-supported autopilot systems for general aviation aircraft.
As many legacy autopilots reach the end of manufacturer support, parts availability and long-term reliability can no longer be assumed. We evaluate existing systems and provide clear upgrade pathways when modernization is the safest and most sustainable solution.
Our installations are structured, documented, and verified prior to return to service — ensuring your autopilot performs as intended.
