PZL hoped that the lower weight of the turbine engine would allow it to manufacture a smaller aircraft with the same capacity as the Kruk. The company also planned the Kawka to share common assemblies with other aircraft in its range. The first flight of a prototype was expected by 1986.

PZL engineers
Andrzej Frydrychewicz and Witold Błażewicz set out to solve a problem with conventionally designed agricultural aircraft. Typically, the spray apparatus of such aircraft is located in the wings, which means that the spray is subject to wastage as it accumulates on the tailplane.

Therefore, Frydrychewicz and Błażewicz gave the aircraft a canard configuration. Because this layout has no tail, and because the piston engine and propeller were mounted at the front of the aircraft, spray could be dispensed from the rear of the aircraft completely unobstructed. Horizontal

Work on the design continued at least into 1987. This iteration of the PZL-107 proceeded as far as constructing and fight-testing a scale model. When this crashed, work on the Kaczor I was abandoned. However, the Polish patents office issued a patent for it in 1990.
