The Glaser-Dirks DG-300 Elan is a single-seat high performance glider from glass reinforced plastic (GRP) , which in the standard class (with 15 m wingspan , steady wing profile and retracting suspension ) was used. The DG-300 was designed by Wilhelm Dirks on the basis of Hansjörg stripeder's " Falcon ". The first flight took place on April 27, 1983.
The aircraft was manufactured by the Slovenian company Elan (later AMS Flight ) for Glaser-Dirks Flugzeugbau GmbH (later DG Flugzeugbau GmbH ). More than 500 of the aircraft, which has been built since 1983, have been delivered.
In addition, the DG-300 can be equipped with flat tanks and a rear tank for water ballast. A comparable aircraft is, for example, the Schneider LS4 roller shutter .
Versions
In addition to the standard version, the DG-300 Club Elan (without blow-out) and the aerobatic DG-300 Elan Acro were also offered, and the Club version also had a non-retractable landing gear. In the early 1990s, the DG-300 was modified to the DG-303. The following was new:
- new hood lock / Röger hook as with DG-800
- modified wing profile
- new backrest with integrated headrest
Shortly thereafter, the manufacturing company ELAN or AMS also took over the sale of the aircraft, DG-Flugzeugbau became the German representative. The same versions were sold as the DG-300. After a while, AMS replaced the blowout with a zigzag band . In early 2006, the 510th and final DG-303 was completed as AMS planned to produce the LS4 instead .
Since the end of 2005, under the type designation GG300, there has been a private, German-approved conversion of a DG-300 to a non- self-launching glider with a fold-out Solo 2350 auxiliary motor and Oehler folding propeller (turbo or homecoming aid).
Airworthiness instruction for the wing spar
In September 2006, while repairing a damaged DG-300, a manufacturing defect was discovered on the wing spars. This also occurred in random samples of other DG-300s. It was then in April 2007 by the DG Flugzeugbau GmbH an airworthiness directive issued after the operating limits of the aircraft have been reduced or alternatively examines the wing spars and could be repaired if negative.
