Aeropro Ninja

Single Piston

The Aeropro Ninja is a Czech-built single-engine ultralight that has carved out a niche in the European microlight market since its introduction in the mid-2000s. Designed and manufactured by Aeropro in the Czech Republic, the Ninja is a high-wing, side-by-side two-seater built around a steel-tube fuselage with fabric covering and composite fairings. It's powered by a Rotax 912 series engine producing 80–100 horsepower, giving it a cruise speed around 90 knots and a range of approximately 500 nautical miles on internal fuel. The type is certified under European CS-LSA and UK SSDR regulations, making it accessible to sport pilots and popular among flying schools and private owners seeking an economical platform for touring and training. The Ninja's relatively low operating costs, docile handling, and spacious cockpit have made it a steady seller in the UK and Central Europe, where it competes with other Rotax-powered microlights like the Eurofox and Ikarus C42. Its 450-kilogram maximum takeoff weight keeps it firmly in the ultralight category, and its short-field performance, requiring less than 300 meters for takeoff, suits grass strips and small airfields. SkyMeter has tracked 120 flights across 12 airframes and 2 operators over routes, with SEITZER DALE the largest observed operator.

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.
