The PZL-101 Gawron (rook) is a Polish agricultural and utility aircraft designed and built by WSK-Okęcie (later PZL "Warszawa-Okęcie").
Because a center of gravity moved rearwards, the plane was fitted with new, swept wings, with significant vertical end plates to improve air flow.
From 1962 the PZL-101A variant was produced, with improved equipment, pilot's seat raised and a right-side door added.
Utility Gawrons were used in aero clubs in the country, also for glider towing and parachute training (with removed right doors).
On 30 March 2007 EADS PZL "Warszawa-Okęcie" S.A. announced that will not longer support their tasks related with flight certificates for Jak-12A, Jak-12M and PZL-101 Gawron.
Two-spar wings, canvas covered, fitted with slotted flaps, slats and vertical edge plates.
In an agricultural variant there was 800-litre container in a fuselage (for 500 kg of chemicals), behind front seats, with exchangeable sets of equipment for spraying or cropdusting.
