Van's Aircraft, Inc. is an American kit aircraft manufacturer, founded by Richard "Van" VanGrunsven in 1973. Van's RV series of aircraft, from the single-seat RV-3 to the latest RV-14, are all-aluminum, low-wing monoplanes of monocoque construction. The RV series of airplanes has been extremely successful, and as of November 2019, about 10,600 RV kits had been completed and flown, and thousands more are under construction. Completion rates currently average about 1.5 per day, making the series the most numerous of all homebuilt aircraft. In 2013, the company announced it would begin selling assembled RV-12 model aircraft as well on a limited basis. In December 2017 the company reported that its 10,000th aircraft had flown, an RV-7 built in Martinsburg, West Virginia. The Van's Aircraft factory is located at Aurora State Airport, Oregon. Regulatory status RVs are deemed Experimental Amateur Built (EAB) aircraft by the Federal Aviation Administration in the United States and are accepted under the corresponding category by the aviation authorities in many other countries, including the United Kingdom, Canada, New Zealand and Australia. A modified version of the RV-6 was sold to the Nigerian government as a kit-assembled military trainer. The RV-12iS is available as an experimental light sport aircraft (ELSA) or special light-sport aircraft (SLSA), which allows for commercial use for purposes like rental and flight training.
