We are selling our well-maintained 2008 FK9 Mark IV Short Wing with a Rotax 912 UL (80 PS) engine that has just passed its 100-hour inspection, along with a new JNP and a new weight certification. We have completed all LTA inspections and are selling the aircraft with a recently repacked rescue parachute, serviced brakes, new brake fluid, and new tires.

The FK9 is a very easy-to-fly and proven ultralight aircraft:
Uncomplicated, reliable, very fuel-efficient, and ideal for leisurely flights, travel, and everyday ultralight flying. The ultralight is in good technical condition and airworthy. It has been regularly maintained and has always been stored in a hangar.

The engine underwent a major repair in early 2025. During this work, a specialized shop completely replaced the camshaft, hydraulic lifters, all gaskets, and much more. All other parts were professionally measured and are within the exact tolerances specified by the engine manufacturer. As part of this process, the carburetors were also overhauled, and the ignition modules were tested by Carmo Electronics.
