Reference price：

   The  Diamond DA40 Diamond Star is an Austrian Four-seat, single engine, Light aircraft, constructed by fiberglass and carbon fiber, its fuselage light and reliable.

Based on the success of the earlier DV20/DA20 two-seat aircraft, the company designed a four-seat variant, the DA40. The DA40 is a four-seat low-wing cantilever monoplane made from composite materials. It has a fixed tricycle landing gear and a T-tail. The Rotax 914-powered prototype DA40-V1, registered OE-VPC, first flew on the 5 November 1997 and was followed by a second prototype DA40-V2 (registered OE-VPE) which was powered by a Continental IO-240. In 1998 a third prototype DA40-V3 flew powered by a Lycoming IO-360 engine. Four more test aircraft were produced followed by the first production aircraft in 2000. JAR23 certification of the IO-360 production variant was obtained in October 2000. In 2002 the production of the Lycoming-engined variant was moved to Canada and the Austrian factory concentrated on diesel-engined variants.

The DA40 has officially appeared in only three versions, the DA 40, DA 40D and DA 40F, as documented on its type certificates. The various model names that the aircraft has been sold under are marketing names and are not officially recognized by the authorities that have certified the aircraft.
