The prototype SZD-51-0 was first flown on 31 December 1980, and was followed by the production version, the SZD-51-1, with a modified fuselage, A total of 261 aircraft were built. The type was proposed for licence production in Brazil, but in the event only a single SZD-51-1 was built there. The simplified SZD-51-2 was a runner up in the IGC World Class design contest.
