History
Aero AT Sp. z o.o. was founded in Warsaw, Poland, in 1994 by Tomasz Antoniewski. The venture was established to design and market a two-seat aircraft for flight training and touring. Its principal development was the Aero AT-3, a single-engine, low-wing very light aircraft with fixed tricycle landing gear. The AT-3 entered the European certification process and obtained EASA type certification in May 1999 under the CS-VLA rules. Available reference material identifies it as the sixth aircraft type to receive certification under those rules. This certification represented the aircraft’s transition from development into an approved European general-aviation product. The first five production aircraft were delivered to customers in 2002. In Europe, the AT-3 was offered in configurations including the SK, or Standard Kit, and the R100. A version adapted for the U.S. light-sport-aircraft market was accepted by the Federal Aviation Administration and marketed as the Gobosh 700. The AT-3-based Gobosh 700S designation is also associated with the American-market offering. Aero AT’s documented aircraft portfolio includes the Aero AT-1, Aero P220S AT-2, Aero AT-3, and Aero AT-4. The AT-3 is the company’s best-known aircraft and the model most directly linked with its identity in general aviation. In 2017, the company introduced the AT-3S at Aero Friedrichshafen. The AT-3S was described as a sport version and a refined variant related to the AT-4, with a reported weight of 600 kilograms. The company is legally organized as a Polish spółka z ograniczoną odpowiedzialnością, a private limited company. It should not be confused with Aero, the Czech aircraft manufacturer. Publicly available information documents the company’s founding, aircraft development, European certification, initial deliveries, and later sport-aircraft presentation, but does not reliably establish its current ownership, production activity, sales volume, or present management. Its current status is therefore recorded as unknown.
