LIBIS KB-11 Branko


The LIBIS KB-11 Branko was a 1950s Yugoslavian four-seat monoplane. The aircraft design office of the Letalski Institut Branko Ivanus Slovenija brought together teachers and students of the Ljubljana technical high school for the KB-11 Branko.

The KB-11 Branko was a development of the earlier two-seat KB-6 Matajur. First flown in December 1959 the KB-11 was an all-metal cantilever low-wing monoplane with retractable tricycle landing gear and an enclosed heated and ventilated cockpit for four persons. Intended for use as an air-taxi our business use but only small numbers were built.
