Maintenance Details

Inspection status: Current Many of the photos shown are of the piston aircraft that was used for testing of the float system. The turbine engine conversion has been completed as can been seen the most recent photos. OEM's were involved with the development of the engine ​/​ prop combination for the AN-2 conversion. There are currently approximately 20 aircraft flying with this conversion setup.

Aircraft Model Overview (Reference only)

The Antonov AN-2 is a Soviet-designed single-engine biplane first flown in 1947 and produced in greater numbers than any other biplane in aviation history — with over 18,000 airframes manufactured across the USSR, Poland, and China over a production span of more than four decades. Designed by Oleg Antonov as a rugged agricultural and utility transport, the AN-2's exceptional STOL performance, near-stall flying capability, and ability to operate from unimproved surfaces established it as one of the most practically versatile aircraft ever built. In turbine amphibian configuration, the AN-2 represents a comprehensive modernization of this foundational design, combining the airframe's legendary bush capabilities with turbine reliability and water operations — a combination found in very few aircraft worldwide at any price point. The baseline AN-2 was powered by the Shvetsov ASh-62IR nine-cylinder air-cooled radial engine producing 1,000 horsepower — a powerplant that, while powerful and characterful, demands significant maintenance attention, specialized knowledge, and parts sourcing that has become increasingly difficult in Western markets. Turbine conversions of the AN-2 replace the radial with a Pratt & Whitney Canada PT6A or Walter M601​/​GE H80 turboprop installation, depending on the STC basis, producing between 680 and 800 shaft horsepower. The turbine conversion typically reduces fuel burn substantially, eliminates the radial's oil consumption and leakage characteristics, and delivers turbine-standard reliability and parts availability — a transformative improvement in the aircraft's practical operability outside of Eastern Europe. The AN-2's biplane configuration is central to its STOL performance capability. The large upper and lower wing panels, full-span leading edge slats on the upper wing, and slotted trailing edge flaps on both wings create exceptional high-lift characteristics at low airspeeds. The aircraft can fly safely at speeds below 40 mph, has no conventional stall in the traditional sense — it simply descends in a controlled mush — and can operate from grass, gravel, ice, and snow strips that would be inaccessible to virtually any other utility transport of comparable payload. The turbine conversion enhances rather than compromises these characteristics, with improved power availability at low airspeeds supporting the aircraft's STOL performance envelope. Amphibious float installation on the AN-2 is accomplished through certified float kits — most commonly ADA (Aeronautical Design Associates) composite amphibious floats or equivalent STC-approved systems — that replace the standard fixed tricycle or tailwheel undercarriage with amphibious floats incorporating retractable wheels for land operations. The combination of wheel, ski (with appropriate winter conversion), and water capability makes the turbine amphibian AN-2 one of the most operationally versatile aircraft available to remote access, bush, and adventure aviation operators. Water handling characteristics reflect the AN-2's large airframe and require type-specific seaplane training for safe operation in confined or rough water conditions. The AN-2 cabin is configured for utility operations rather than executive comfort, but is notable for its large interior volume relative to the aircraft's overall footprint — capable of accommodating up to 12 passengers in a high-density configuration or substantial bulk cargo loads in freighter fit. The wide cabin door on the left side of the fuselage accommodates bulky equipment and facilitates parachute operations, aerial survey, and load delivery missions that have defined the type's utility role across generations of operators. In amphibian configuration, passenger and cargo loading from water requires attention to float freeboard and step access, which varies by float system installation. The AN-2 Turbine Amphibian occupies a uniquely capable and essentially uncontested niche in the utility aviation market: no other certified aircraft combines the AN-2's STOL performance, payload capacity, and operational versatility with amphibious float capability and modern turbine powerplant reliability. The type attracts a specific and knowledgeable buyer — remote lodge and outfitter operators, expeditionary aviation programs, government survey agencies, and serious bush pilots who require access to destinations unreachable by any other means. Support infrastructure in North America is growing as the turbine conversion market has matured, but buyers should approach ownership with realistic expectations regarding specialized maintenance requirements and parts lead times for AN-2-specific components.
