The Sunny Sport UL-biplane was designed by Dieter Schulz. Production by
Tandem Aircraft KG started in 1989. The first year, 25 Sunnies were sold.
However the Sunny appeared to be a safe and stable aircraft, the sale
figures of the Sunny went down over the years. This resulted in the bankruptcy of Aircraft KG in 1999.
The undoing of Tandem Aircraft KG was not the end of the Sunny as Alexander Dewald bought the rights. Both the
tandem-seat Sunny Sport and the side-by-side versions are now produced
in the factory of Dewald Leichtflugzeugbau at Schönborn-Mingolsheim near
Speyer in Germany. Both versions feature a number of small, but
significant, design changes
On 28 February 1992, Tandem Air Sunny c/n 28.92 was registered PH-2G4 in the Netherlands. The registered type of the aircraft changed into
Tandem Air Sunny Sport on 15 January 1998. After the CofA expired over a year, registration PH-2G4 was cancelled
on 10 October 2006. Tandem Air Sunny Sport PH-2G4 was photographed at Lelystad Airport in the Netherlands.
