Piper Aircraft J3

Single Piston

The Piper J-3 Cub is arguably the most iconic light aircraft in American aviation history, a fabric-covered taildragger that taught generations of pilots to fly and became synonymous with grassroots general aviation itself. First produced in 1938 by what was then the Taylor Aircraft Company (soon renamed Piper), the J-3 was designed as an affordable, forgiving trainer with tandem seating, a Continental A-65 engine producing 65 horsepower, and handling characteristics so benign that student pilots could solo after just a few hours of instruction. More than 19,000 Cubs were built before production ended in 1947, with thousands serving as military trainers during World War II under the L-4 Grasshopper designation, spotting artillery and ferrying liaison officers from improvised strips across every theater of war. The Cub's slow-flight capability, short takeoff and landing performance, and docile stall made it ideal for backcountry flying, banner towing, and low-altitude observation work that continues today. Its cruise speed of around 75 knots and never-exceed speed of 87 knots reflect an era when flying was less about speed than about the pure joy of being aloft, and its stall speed below 40 knots allows operations from farm fields, sandbars, and mountain ridges inaccessible to faster aircraft. The J-3's enduring popularity has spawned an entire ecosystem of parts suppliers, restoration shops, and modern reproductions like the CubCrafters Carbon Cub that honor the original's DNA while incorporating contemporary materials and powerplants. SkyMeter has tracked 142 flights across 48 airframes and 40 operators, with BETA FLEET LLC 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.
