The PZL-106 was developed as a modern agricultural aircraft for Poland and Comecon countries, to replace the less capablePZL-101 Gawron and aging PZL Antonov An-2. (According to Comecon decisions, Polish industry was responsible for developing agricultural aircraft). . That remained a paper aeroplane, but did give its name to later designs.Next were the PZL-106 Kruk 65 (1965), PZL-110 Kruk-2T (1969) and PZL M-14 Kruk (1970, it was planned to produce this variant inPZL-Mielec). Only in 1971 did the authorities decide to start development of the new agricultural design as the PZL-106 Kruk 71. Despite this decision, its development was quite protracted, due to both economic and political reasons. The work, led byAndrzej Frydrychewicz, started in 1972, and was based on earlier designs. The first prototype was flown on April 17, 1973.The designers chose a safe layout of a braced low-wing monoplane with a container for chemicals in front of the pilot, and wasinspired by planes like Piper PA-25 Pawnee.
