The avionics landscape is changing fast — and staying informed is the key to keep flying with confidence.
Over the past few years, MOOG Avionics has announced several major shifts in direction, and these changes directly impact support, availability, and long‑term planning for S‑TEC and Genesys products. As your long‑time aviation partners, we want to make sure you have the clarity you need to plan.
A Strategic Pivot at MOOG Avionics
MOOG Avionics is moving its focus toward Part 25, Part 27, Part 29, and military platforms, signalling a step away from traditional GA autopilot lines. For many operators and maintainers, this means preparing for transitions in product support and availability.
Key Updates You Should Be Aware Of
✔ March 2026 — S‑TEC 3100 Sold to Innovative Aerosystems Dealers were notified that the S‑TEC 3100 product line has been sold to Innovative Aerosystems. For the first two months, business continues as normal, after which Innovative Aerosystems will take over sales and support.
✔ December 2025 — System 55X Sunsetting MOOG announced the sunset of the System 55X autopilot, including a last‑time‑buy opportunity.

✔ July 2022 — Legacy Analog Autopilot Computers Moog confirmed the sunsetting of S‑TEC legacy analogue autopilot computers, with support continuing only while components remain available.
