The Iryda is a training aircraft developed in the 1970s and 1980s at the Institute of Aviation in Warsaw as a successor to the TS-11 Iskra. The prototype, built at the WSK PZL Mielec plant, was first flown in 1985. It was powered by PZL-5 engines. In 1992, the prototype of the M-93K version, powered by the intended K-15 engines, was first flown. Between 1992 and 1996, the 58th Aviation Training Regiment in Deblin operated 8 examples.
Due to the prolonged development period, the Iryda was already an outdated design with numerous problems by the time it entered service. After a crash in 1996 in which two pilots were killed, the aircraft were withdrawn from use. Work on the aircraft continued, and prototypes of versions with Rolls Royce Viper engines and avionics from the French company Sagem were also built, but they never entered serial production or operational service.
