The UL-39 Albi is a Czech ul two-seater aircraft modeled after the L-39 Albatros jet trainer. The use of a classic turbine engine was not feasible for a UL category plane and so a fan-ducted impellor driven by a piston engine is used for propulsion with almost all of the fuselage composed of autoclaved pre-impregnated carbon fibre. The initial inspiration and testing was performed by the Institute of Aviation Technology (Ústav letadlové techniky) and the concept is being brought to the market by Jihlavan Skyleader. The improved, second prototype fuselage is visible to the right.
