Scheibe Flugzeugbau Sf-28a Tandem Falke

Single Piston

The Scheibe SF-28A Tandem Falke is a German two-seat motorglider that bridges the gap between pure sailplanes and conventional light aircraft. Built by Scheibe Flugzeugbau from the 1970s onward, the Tandem Falke features an unusual tandem seating arrangement rather than the side-by-side configuration common in training aircraft, giving both occupants excellent visibility and a glider-like cockpit experience. Powered by an 80-horsepower Limbach flat-four engine, the SF-28 can self-launch and sustain powered flight, but its high-aspect-ratio wings and clean aerodynamics allow it to soar efficiently once the engine is throttled back or shut down entirely. With a maximum takeoff weight of just 550 kilograms and a stall speed below 40 knots, the Tandem Falke operates from short grass strips and is popular with gliding clubs across Europe for training, cross-country touring, and introducing pilots to the fundamentals of soaring flight. The type's gentle handling, modest operating costs, and dual-role capability have kept it in service for decades, particularly in Germany where motorgliders remain a staple of the general aviation fleet.

Safety in context

The incident rate counts flights with ANY safety event detected by SkyMeter — go-arounds (a routine response, not a failure), unstable-approach gate flags (advisory thresholds), rejected takeoffs (the system working as designed), and runway events. It is NOT an accident rate or fatality rate. For accident statistics, refer to the NTSB Aviation Accident Database (USA) or the Aviation Safety Network. See methodology for what each event type measures.
