Aerospool Wt9 Dynamic (JFOX)
ICAO JFOX Light Piston

Aerospool Wt9 Dynamic

Single Piston

The Aerospool WT9 Dynamic is a Slovak-designed two-seat light sport aircraft that has become popular in the European ultralight and LSA markets since its introduction in the early 2000s. Built by Aerospool in Prievidza, Slovakia, the WT9 features a distinctive low-wing configuration with a composite fuselage and a choice of Rotax piston engines, typically the 100-horsepower Rotax 912ULS. The aircraft is certified under both European ultralight regulations and the U.S. Light Sport Aircraft category, making it accessible to sport pilots on both continents. Its efficient design delivers cruise speeds around 120 knots while maintaining excellent fuel economy and docile handling characteristics that appeal to both training operations and private owners. The WT9's spacious tandem cockpit, good visibility, and modern avionics options have made it a competitive alternative to more established LSA designs. SkyMeter has tracked flights across airframes and operators, with distinct routes observed.

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.
