Remarks: The B&F Fk9 is a German designed single engine, two seat ultralight, first flown in 1989. It has been developed from a mixed structure, fabric covered aircraft to a wholly composite machine. It remains in production at factories in Germany and Poland and has sold in large numbers, flying in four continents. The Fk9 prototype first flew early in 1989, making its first public appearance that April at the Aero trade fair in Friedrichshafen. By late 2008, before the introduction of the ELA variant, at least 370 Fk9s of all types had been sold. The mid-2010 European registers (excluding Russia) note 387 aircraft, including 4 ELAs. Other Fk9s fly in North and South America, where there are agencies, as in South Africa. US LSA for kits was given in 2005. UK microlight weight limits exclude the Fk9 as an assembled aircraft, but the recent ELA regulations are expected to allow that version to be registered.
