Sling Aircraft Sling 4

Single Piston

The Sling 4 is a South African-designed four-seat light aircraft built by The Airplane Factory and marketed globally as an amateur-built kit. First flown in 2012, it represents a modern take on the touring aircraft category with all-metal construction, side-stick controls, and a spacious cabin that seats four adults in relative comfort. The design emphasizes cross-country capability with a useful load around 900 pounds and cruise speeds in the 140-knot range, powered by a Rotax 914 turbocharged engine that delivers strong performance at altitude. What sets the Sling 4 apart in the experimental aircraft market is its blend of European sport-plane handling with genuine four-seat utility, a niche where many designs compromise either payload or speed. The aircraft has found favor with owner-builders seeking a capable tourer that can be assembled from a complete kit, and it's proven popular enough to spawn a certified variant (the TSi) aimed at flight schools and commercial operators. With a never-exceed speed of 165 knots and a stall speed below 50 knots in landing configuration, the Sling 4 offers a comfortable operating envelope for pilots transitioning from trainers to cross-country machines. SkyMeter has tracked 3 flights across 2 airframes and 2 operators over routes, with SKY WEST AVIATION INC TRUSTEE 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.
