The Ravin 500 is a South African amateur-built aircraft, designed and produced by Ravin Aircraft of Pretoria. The aircraft first flew on 15 September 2002 and is supplied as a kit for amateur construction or as a complete ready-to-fly aircraft.[1][2]

Design and development

The Ravin 500 is based on the design of the aluminum Piper PA-24 Comanche, but rendered in composite materials and scaled down some 6–7%.[3]

The Ravin 500 features a cantilever low-wing, a four-seat enclosed cabin, accessed by doors, retractable tricycle landing gear and a single engine in tractor configuration. The cabin is {{convert|45|in|cm|0|abbr=on}} wide.[1][2]

The aircraft's {{convert|35|ft|m|1|abbr=on}} span wing has an area of {{convert|157|sqft|m2|abbr=on}} and mounts flaps as well as winglets. The aircraft's recommended engine is the {{convert|260|to|300|hp|kW|0|abbr=on}} Lycoming IO-540 four-stroke powerplant. Construction time from the supplied kit is estimated as 1400 hours.[1]

Operational history

The company reported that by December 2013 that a total of 22 aircraft or kits had been supplied and that 17 of these have been completed and flown.[4]
