Ultraleichtflugzeug Meier Uf-13 Kolibri
Single Piston
The UF-13 Kolibri (Hummingbird) is a German ultralight aircraft designed and manufactured by Ultraleichtflugzeug Meier, representing the European tradition of efficient, lightweight recreational aviation. Built primarily for the German and European ultralight market where aircraft are limited to 450 kg maximum takeoff weight, the Kolibri exemplifies the engineering compromises required to deliver safe, enjoyable flight within strict regulatory constraints. Its single-seat or tandem two-seat configuration, fabric-covered tube frame, and modest Rotax or similar two-stroke engine make it accessible to sport pilots seeking low operating costs and straightforward maintenance. The type's slow-flight characteristics—stalling around 35 knots with flaps and cruising in the 65–75 knot range—suit it well for local recreational flying, flight training under ultralight rules, and short-field operations from grass strips. While unremarkable in performance compared to certified light aircraft, the UF-13's appeal lies in its simplicity, affordability, and compliance with European ultralight certification standards that have made recreational aviation accessible to thousands of pilots. SkyMeter has tracked 9 flights across 4 airframes and 4 operators over routes, with XRAY MIKE INC the most frequently 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.
