rules which discarded the old Olympic 15-15-15 Span, Aspect Ratio, Area rule. The first flight of the SZD-22 took place at Bielsko with Adam Zientek at the controls on 10 February 1958. It was followed by the second prototype in June 1958. Flight trials were successful, leading to a long production run with six variants, which introduced various modifications. Built primarily of wood, the SZD-22 had airbrakes in the wings, a streamline cockpit canopy, short nose and tail skids with a single mainwheel. The SZD-22C model replaced the plywood covering of the wings with fabric and some models had provision for water ballast in rubber bags fitted to the wing roots. Most of SZD-22s – 271, were built in ZSLS in Krosno. Many SZD-22's, mostly SZD-22C models, were exported to the Great Britain, Argentina, Austria, Australia, Belgium, Denmark, Finland, France, Greece, Yugoslavia, Mexico, Norway, West Germany, Switzerland, Sweden, Tunisia, Turkey, USA, Hungary and Italy Adam Witek flew the SZD-22 Mucha Standard to first place in the Standard class at the 1958 World Gliding Championships at Leszno in Poland.
