PZL-101 is an agricultural aircraft, single-engine, high-strut wing, metal structure, covered with duralumin sheet, 0.4-1.0 mm thick, and canvas.


The PZL-101 Gawron planes received rectangular wings and fixed gills (slots) on the leading edge. At the ends of the airfoils, it received large aerodynamic blades (edge ​​plates). The wings have a bevel of 4 degrees. After the conversion from the agricultural version to the multi-purpose version, the edge plates were often dismantled.

The fuselage.

The fuselage of the truss structure, made of 30HGSA steel pipes. They are profiled with duralumin stringers. The front part of the fuselage is covered with D16A-T duralumin sheet. The back is covered with AM-100 natural or synthetic canvas. The fuselage begins with a firewall made of steel sheet. The bed is attached to this partition, and the engine to it. Access to the hull is provided by doors on both sides. They have an emergency dump system. The windows are made of organic glass. The PZL-101 Gawron received a raised ridge, which created a slight hump and significantly increased the space in the cabin. The walls of the cabin are upholstered. There are four seats in the cabin; two seats in the front and a couch in the back. The front seat backrests tilt forward to facilitate rear seat occupancy. Behind the cabin there is a trunk, which can be accessed through a door mounted on the left side. Radio equipment was also placed here.
