Pzl-Świdnik Pzl-104 Wilga

Single Piston

The PZL-104 Wilga is a Polish high-wing utility aircraft known for its exceptional short takeoff and landing capabilities, designed in the early 1960s by PZL-Warszawa-Okęcie and later produced by PZL-Świdnik. The name "Wilga" means "golden oriole" in Polish, reflecting the aircraft's agility and versatility. Originally developed for agricultural work, glider towing, parachute training, and liaison duties, the Wilga became one of Eastern Europe's most successful light aircraft exports, with over 1,000 built across multiple variants through the 1990s. Its rugged construction, fixed tailwheel landing gear, and powerful radial or inline piston engine made it ideal for operations from unprepared strips and rough terrain. The Wilga's design emphasizes utility over speed, with a stall speed around 43 knots in landing configuration and a never-exceed speed of 143 knots, giving it a wide and forgiving flight envelope. The high-mounted wing provides excellent visibility and ground clearance, while the spacious cabin accommodates a pilot and up to three passengers or equivalent cargo. Operators have used Wilgas for everything from aerial photography and pipeline patrol to bush flying and recreational aviation. The type remains popular with private owners and flying clubs across Europe, particularly in Poland and Germany, where its STOL performance and straightforward maintenance continue to appeal to pilots seeking a capable backcountry aircraft.

Safety in context

The incident rate counts flights with ANY safety event detected by SkyMeter: go-arounds (a routine response, not a failure), unstable-approach gate flags (advisory thresholds), rejected takeoffs (the system working as designed), and runway events. It is NOT an accident rate or fatality rate. For accident statistics, refer to the NTSB Aviation Accident Database (USA) or the Aviation Safety Network. See methodology for what each event type measures.
