The '''PZL M-17 "Duduś Kudłacz"''' (initially '''EM-5A''') was a Polish twin-boom pusher [[general aviation]] and trainer aircraft of 1977, which remained a prototype.

==Design and development==
The aircraft was an amateur design of a team of students of [[Warsaw University of Technology]] (Politechnika Warszawska) led by [[Edward Margański]]. It had an unorthodox layout of a [[Pusher configuration|pusher]] with twin booms and very streamlined fuselage. A crew of two sat side by side, and had double controls. A tricycle landing gear was retractable.

The plane was designed in 1969–1971. At the design stage it was designated '''EM-5A''' (EM for Margański) and nicknamed Duduś Kudłacz (''Hairy Duduś''). The aircraft factory [[PZL-Mielec]] in [[Mielec]] got interested in the design and took over its development, under a designation '''PZL M-17'''. The design was modified there with help of Margański, plastic and duralumin construction was changed to riveted duralumin, and a less powerful engine.

The only prototype was flown on 7 July 1977 by S. Wasil. It was not produced in series. In 1979 the prototype was given to [[Rzeszów University of Technology]]. A shortcoming of a streamlined fuselage was a cramped cockpit, the crewmen were half-laying in a similar way, as in [[Glider (sailplane)|gliders]].

The plane was a mid-wing monoplane. It had a two-blade wooden propeller and a 310-liter fuel tank .
