Pitts S-2c

Single Piston

The Pitts S-2C is a two-seat aerobatic biplane that represents the pinnacle of unlimited competition aerobatics design from the legendary Pitts lineage. Built by Aviat Aircraft (formerly Christen Industries), the S-2C evolved from Curtis Pitts' original 1940s designs and became the weapon of choice for world-class aerobatic competitors through the 1980s and 1990s. Powered by a 260-horsepower Lycoming AEIO-540, the S-2C delivers an extraordinary power-to-weight ratio and roll rates exceeding 360 degrees per second, capabilities that made it a dominant force in International Aerobatic Club competitions and airshow circuits worldwide. The type's symmetrical airfoil and balanced control harmony allow sustained inverted flight and knife-edge maneuvers that would be impossible in conventional aircraft. With a never-exceed speed of 194 knots and a design load factor of +6/-5 Gs, the S-2C operates in a flight envelope far beyond typical general aviation aircraft. Its distinctive stacked-wing silhouette and fabric-covered steel tube fuselage represent traditional construction methods refined to their absolute limits. While production ended in the early 2000s as composite aerobatic designs emerged, the S-2C remains highly sought after by serious aerobatic pilots and warbird collectors. SkyMeter has tracked 8 flights across 5 airframes and 1 operators, with the most frequently 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.
