TYPE: Two-seat lightplane; four-seat lightplane.
PROGRAMME: Redesign of GlaStar to JAR 23 certification standards began in May 1998. First prototype (D-ETCW, c/n P1) was essentially unchanged and first flew May 1999; second prototype D-EMVP (c/n 0001), with modifications to meet JAR 23, first flown 7 October 1999; third aircraft (D-ENVG) had not flown by June 2000, when it made type's public debut at Berlin Air Show. LBA evaluation began mid-July 2000 and certification and production certificate both awarded 29 August 2000; FAA certificate A43CE awarded 9 April 2001; Transport Canada certification awarded 30 June 2003. IFR certification issued June 2002. Customer deliveries began November 2001.

DESIGN FEATURES: Intended to be an inexpensive trainer and lightplane. Completely redesigned landing gear and wing; retains only some 10 per cent commonality with GlaStar. Crashworthy cockpit and seats. Around 60 per cent of aircraft built by OMF; remainder sourced from abroad, including Czech Republic (aluminium flying surfaces), Poland, France, UK and USA. Service life of 18,000 hours. Braced, unswept high wing of constant chord; foldable for storage. Tailplane has curved, leading-edge root strakes; tall, sweptback fin. Centre-section of top wing thickened in late 2001, increasing maximum T-O weight.
FLYING CONTROLS: Conventional and manual. Mass-balanced Frise ailerons with three hinges each (compared to GlaStar's two), travel up 23°/down 17°; electrically operated, metal, three-position Fowler flaps (0, 20 and 40°). Horn-balanced, single-piece elevator with anti-balance tab, travel up 21°/down 20°; horn-balanced rudder, travels 21° in each direction. Vortex generators added to wings in front of ailerons and at wing roots.
STRUCTURE: Fuselage of GFRP with 4130 steel tube frame strengthening in cockpit area. Metal wings, struts, flaps, ailerons, tailplane, elevator and rudder; composites wingtips, fin fillet, tailplane strakes and wheel fairings.
LANDING GEAR: Tricycle type; fixed. Castoring nosewheel. Sprung steel mainwheel legs; Cleveland hydraulic brakes. All wheels 5.00-5 and have speed fairings. Nosewheel turning 6.7 m (22 ft).
POWER PLANT: Symphony 160: One 119 kW (160 hp) Textron Lycoming O-320-D2A flat-four, driving a two-blade fixed-pitch MT-186R-140-3D P-244-3 propeller.
