The PZL-112 Junior was designed by PZL Warszawa-Okecie in collaboration with the Warsaw University of Technology as a low-cost trainer for Polish flying clubs. It was originally known as the Koliber Junior as it used some components from the PZL-110 Koliber. The Junior is a metal low-wing cantilever monoplane with a swept back vertical tail and a small ventral fin. It has a fixed tricycle landing gear and is powered by a nose-mounted Lycoming O-235-L2C flat-four piston engine driving a two-bladed propeller. It has two side-by-side configuration seats in an enclosed cabin with a gull-wing canopy. Construction of the prototype was started in 1997 and it first flew on 17 Jun 2000.
