About the B&F Technik Vertriebs GmbH FK9 Mark IV

The B&F Technik FK9 is a German-designed two-seat high-wing ultralight and light sport aircraft that has become one of Europe's most popular homebuilt and factory-built light aircraft since its introduction in the mid-1990s. Built by B&F Technik Vertriebs GmbH in Speyer, Germany, the FK9 Mark IV represents the latest evolution of a design optimized for simplicity, affordability, and excellent short-field performance. Its all-composite construction keeps empty weight around 290 kg (640 lb) while maintaining structural strength, and the spacious side-by-side cockpit offers better visibility than many competing designs thanks to its high-wing configuration and large Perspex canopy.

The FK9 is certified under both European ultralight regulations (472.5 kg MTOW) and as a Special Light-Sport Aircraft (S-LSA) in the United States, where it competes with American designs like the Flight Design CT and Tecnam P92. Powered by Rotax 912-series engines producing 80-100 horsepower, the FK9 cruises comfortably at 100-110 knots while sipping just 4-5 gallons per hour, and its low stall speed of 37 knots with full flaps makes it forgiving for student pilots and ideal for grass strips. The type's modular construction allows builder customization, and kits have been exported worldwide, though the majority of the fleet remains in Germany and Central Europe where ultralight aviation thrives.

SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
