Aero AT At-3

Single Piston

The Aero AT-3 is a Polish four-seat single-engine aircraft built by Aero AT in Krosno, Poland, and represents one of Europe's few modern all-composite general aviation designs to achieve series production. First flown in 2003 and certified under CS-23 in 2006, the AT-3 was developed as a touring and training platform emphasizing efficiency, with a composite airframe that delivers a useful load exceeding 900 pounds and a cruise speed around 135 knots on a 100-horsepower Rotax 912S engine. The type's low empty weight (under 1,300 pounds) and spacious cabin made it popular with European flight schools and private owners seeking an economical four-seater, though production remained limited compared to legacy Cessna and Piper models. The AT-3's operating envelope is typical of modern light singles—never-exceed speed of 162 knots, normal operations to 135 knots, and stall speeds in the low 50-knot range—with handling characteristics that favor stability over aerobatic capability. While the type never achieved widespread international adoption, it carved out a niche in Central Europe as a cost-effective trainer and tourer. SkyMeter has tracked 32 flights across 6 airframes and 1 operators, with operations concentrated over routes.
