built the Kappa Sova for Kappa 77 from 1997 to 2004 and obtained marketing rights in 2005 when Kappa became insolvent. They became a subsidiary of Skyleader Aircraft in 2008 when the type was redesignated Jihlavan Skyleader. It is an all-metal design apart from a carbon fibre cockpit frame. It has two-spar tapered wings with 6° of dihedral, electrically operated Fowler flaps and upturned Küchemanntips. The fin and rudder are swept. The straight tapered tailplane is set on top of the fuselage, the port elevator carrying a trim tab. The Bulgarian company ACS started producing the Skyleader 600 at the state owned TEREM-Letets aircraft factory in Sofia in July 2015 under a licence agreement. The original Sova/Skyleader 150 has staggered side-by-side configuration seating with the starboard seat 200 mm aft of the other, but a widened fuselage allows the Skyleader 200 to have true side-by-side seating. The earlier version has a forward-hinged canopy with fixed rear transparencies; the Skyleader 200 has a single-piece canopy. Both these variants normally have an electrically actuated tricycle undercarriage with a steerable nosewheel, though a fixed version is an option and is standard on the later Skyleader 500 and 600 variants. The standard engine for the 150/200 variants is a 60 kW Rotax 912UL, though the more powerful Rotax 912ULS or Rotax 914 can be fitted, all driving a choice of two-blade propellers. The 500/600 variants can also use the Rotax 912 UL or Rotax 912S; the Jabiru 2200 or 3300 engines may also be fitted. The Skyleader 500/600 variants have three-blade propellers. The Kappa 77 KP-2U Sova first flew on 26 May 1996 and the KP-5 Rapid 500 in December 2003. Czech certification was achieved in September 1997 and March 2004 respectively. The Skyleader is produced in both kit and flyaway form.

Accidents and incidents
In May 2016 a Skyleader 500 crashed in Rhoadesville, Virginia, United States, killing the two occupants of the aircraft. The Galaxy Rescue Systemsballistic parachute had been deployed, but the single front riser failed, leading to the parachute failure. The aircraft had been practicing slow flight and stalls and most likely entered a spin, from which the parachute was deployed. The aircraft was over maximum weight at the time of the accident. The GRS parachute model had never been tested in the air on this aircraft design and had only been ground tested once. A new double front riser system is now in use.
