Your Liberty XL-2, reborn without FADEC.
The XL-2 neo STC removes dependency on the deprecated Continental PowerLink FADEC by replacing it with a certified dual modern ignition and fuel-injection system — retaining your engine's potential up to original TBO, without the unscheduled groundings.
Fadectomy at AirVenture Oshkosh — all week
The Fadectomy team will be on site for the full duration of EAA AirVenture Oshkosh, meeting current and prospective Liberty XL-2 owners. The XL-2 neo demonstrator itself is based nearby — see the Oshkosh visit details below for the schedule and travel note.
ConfirmedXL-2 neo redesign eliminates engine mount modification
A redesign of the XL-2 neo installation removes the need to modify the engine mount to make room for the magnetos — one of the more invasive steps in the original conversion. A second aircraft is now under conversion using the revised design.

The aircraft is on display at the Appleton Flight Center FBO, KATW — Appleton International Airport, roughly a 45-minute scheduled bus ride or drive from Oshkosh.

Why a Liberty XL-2 needs a Fadectomy
If you fly or operate a Liberty XL-2, you already know the airframe — but you could do without the maintenance nightmare caused by the Full Authority Digital Engine Control installed on it.
The PowerLink™ FADEC fitted to the Continental IOF-240-B engine was certified in the mid-1990s. Its components are increasingly hard to source: stock is now depleted both at Continental and at the original component manufacturers. The result is aircraft that are airworthy in every respect except one — a faulty FADEC with no quick fix.
The result is an STC that removes the unmaintainable FADEC, reinstalls a conventional fuel-injection system and a proven ignition system, and integrates the change into the airframe as if it had been built that way from the start.
The XL-2 neo flew for the first time on March 15, 2024, under an experimental / market-survey airworthiness certificate.
Flight testing is underway to generate the data required for final STC approval. No release date or pricing has been announced.
A second aircraft is currently being converted, incorporating the July 2026 redesign that removes the engine-mount modification.
What the STC changes
The engine's remaining potential is retained up to its original TBO — there's no need to change the installed engine.
| Removed | Installed |
|---|---|
| PowerLink™ FADEC (Continental) | Advanced FAA certified dual ignition system with harness |
| FADEC-managed fuel control | Proven fuel-injection system — injectors, mixture lever, engine instrumentation |
| Original engine mount — no longer required (Jul 2026 redesign) | Standard engine mount, unmodified |
- Installed engine's potential retained to original TBO
- No more unscheduled, indefinite groundings
- No more chasing unobtainable FADEC spare parts
- Reliable dispatch rate makes low-cost instruction viable again
- No engine mount modification required (as of the July 2026 redesign)
- Second conversion aircraft now underway on the revised design
Two options for your Liberty XL-2
How the XL-2 neo came together
A flying school asks for a fix
A flying school operating a small XL-2 fleet in the USA and Switzerland approaches George Aviation about grounded aircraft with no FADEC parts available.
STC engineering begins
George Aviation, in a joint venture with EcoFlight training, begins engineering an STC to remove the FADEC and reinstall conventional ignition and fuel-injection systems.
First flight
The XL-2 neo demonstrator flies for the first time under an experimental / market-survey airworthiness certificate.
Flight test program
Testing continues to generate the data required for final STC approval.
Engine-mount redesign
The installation is redesigned to remove the need for engine mount modification. A second aircraft enters conversion on the new design, and the team meets owners all week at AirVenture Oshkosh, with the aircraft on display at the Appleton Flight Center FBO, KATW.
