The Schleicher ASG 29 is a German sailplane in production by Alexander Schleicher GmbH & Co since 2006. It can be flown as an 18 metre Class glider or as a 15 metre Class glider. The 'G' indicates this is a design of designer Michael Greiner. It is a refinement of the popular ASW-27 and for certification purposes it is designated the ASW-27-18.The ASG 29 has plain flaps and winglets. The structure is a complex composite of carbon, aramid and polyethylene fibre reinforced plastic. This permits a light structure with the strength to carry up to 170 liters (322 pounds) of water ballast, thus permitting the widest possible range of wing loadings for weak and strong soaring weather. The unmotorised version made its first flight on 9 November 2005. The 'E' version has a self-sustaining engine (SOLO 2350, 18 hp 2-stroke) and was certified in February 2008. By August 2014 the numbers of ASG29 produced had reached 163 turbos and 87 pure gliders.
