ICAO FB5 Light Piston

Fly Synthesis Storch S

Single Piston

The Fly Synthesis Storch S is an Italian-built light sport aircraft inspired by the legendary Fieseler Fi 156 Storch, designed for exceptional short takeoff and landing performance. Introduced in the early 2010s by Fly Synthesis of Alzate Brianza, Italy, the aircraft combines modern composite construction with classic STOL capability, featuring high-lift wing devices, full-span leading-edge slats, and large trailing-edge flaps that enable operations from unprepared strips and confined spaces. Powered by a 100-horsepower Rotax 912 ULS engine, the Storch S achieves a stall speed as low as 35 knots in landing configuration and can operate comfortably from grass strips under 500 feet. The tandem two-seat configuration provides excellent visibility for both occupants, making it popular among bush pilots and recreational aviators seeking backcountry capability without the complexity of certified aircraft. Its never-exceed speed of 135 knots and normal operating speed of 108 knots reflect its focus on low-speed handling rather than cross-country speed, while the maximum takeoff weight of just 1,323 pounds keeps it firmly in the light sport category.

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.
