Fk-Lightplanes Fk12 Comet

Single Piston

The FK12 Comet is a German-designed single-engine light sport aircraft built by FK-Lightplanes, a small manufacturer based in Speyer. First flown in the late 1990s, the Comet occupies the ultralight and light sport aircraft category popular across Europe, where it serves recreational pilots seeking an affordable, simple aircraft with docile handling characteristics. The FK12 features a high-wing configuration with excellent visibility, tricycle landing gear, and side-by-side seating for two occupants. Powered by Rotax four-stroke engines in the 80-100 horsepower range, the Comet achieves a maximum cruise speed around 108 knots while maintaining a stall speed below 50 knots, making it accessible to sport pilot certificate holders and well-suited to short-field operations. Its maximum takeoff weight of 1,433 pounds places it firmly in the European ultralight class, and its straightforward construction appeals to owner-builders and flying clubs. The type remains in limited production and is primarily registered in Germany and France, where it serves the recreational aviation community. SkyMeter has tracked 6 flights across 3 airframes and 1 operators, with activity concentrated across routes.
