In 1976, a program to develop a new jet trainer for the Polish Air Force started at the Institute of Aeronautics (Polish: Instytut Lotnictwa) to replace the TS-11 Iskra. The Iryda was designed in PZL Mielec (then WSK-Mielec). The first prototype was flown on March 3, 1985. The project was finally canceled in the 1990s due to problems and a lack of funding. Another reason was a crash of the pre-production series aircraft, even though the cause of accident was exceeding of the performance limits during forced flutter tests.
