Excerpt: PZL-104 Wilga (Golden Oriole) is a Polish designed and built short-takeoff-and-landing (STOL) Civil Aviation utility aircraft manufactured by PZL "Warszawa-Okcie";. The Wilga has evolved through many ever improving versions during its continuous production run from 1962 to the present. The PZL-104 was designed for robust use in sports, civil aviation, with a strong emphasis on glider-towing and parachute training. The prototype of the initial Wilga Mark 1 variant was first flown on April 24 1962 and was engined with an existing Polish 220 hp horizontally-opposed engine the PZL WN-6RB. The Wilga 1 prototype exposed a number of design faults, the most serious of which was excessive weight and a rear view restriction such that the crew could not easily see a towed glider. This resulted in an airframe review that thoroughly redesigned the aircraft, led by Bronisaw urakowski and Andrzej Frydrychewicz. They started by retaining major structural elements and successful sub-assemblies from the wings in the initial design. A completely new slimmer, strengthened fuselage was added that also offered an excellent rear view aspect for the crew during glider towing operati...
