S-80 is the first commercial aircraft of the design bureau (leaving aside aerobatic planes). Rugged construction STOL transport aircraft of advanced technology with rough field capability, the S-80 is designed to replace thousands of Yak-40, An-2, An-24, An-26, An-30, An-32, An-28 and L-410. Since most of these aircraft were manufactured outside Russia, Russia's aircraft companies were faced with the practically insoluble problem of how to repair and renovate their fleets. As an aircraft without any predecessors, the S-80 was initially developed as highly effective transport suitable for use on both commuter and medium-range airlines. As many as 650 aircraft in different configurations may be sold by the year 2006.
The aircraft has a two-beam design with a high-aspect wing provided with improved high-lift devices. It has a roomy flight deck and comfortable 26-seat cabin. Owing to its inverted U-shaped tail unit and hinged cargo ramp in the fuselage tail, the aircraft may be loaded/unloaded right from/to a transport vehicle.
The plane boasts a pressurized flight deck and passenger cabin, great autonomy in operation, high reliability and long life - even under the most inclement climatic conditions.
Since the S-80 is intended also for export, its major engine option is GE's commercially successful CT7-9B turboprop, driving Hamilton Standard 14RF propeller (different photos show 4 or 6 blade configurations). The 14RF, suitable for up to 2,000-shaft horsepower, features lightweight, field-replaceable, composite spar/shell blades and a highly accurate control system featuring synchrophasing for low noise.
Calculations indicated that an increase in the sale price of the plane, due to the use of imported turboprops and propellers, will be more than compensated by their outstanding reliability, long life and extremely low operating costs. Moreover, the joint venture set up by General Electric and stock company Rybinskiye Motory will produce such engines and also organize their in-service maintenance support on the Russian market.
The state-of-the-art avionics of the plane is also extremely important. A part of the plane is being developed anew (e.g., airborne computers, indicators, navaids), while some are vendor items (radio communication equipment, weather radar, ATC transponder, IFF, etc.). Export variants will be fit with the Rockwell Collins avionics.

The dimensions of the S-80, construction materials and technologies used are similar those of the Su-27 aircraft. This means that the company has already mastered the manufacture technology of S-80 components and has at its disposal all the facilities and working areas required to produce 24 aircraft annually. At present modernization work is underway involving separation of the final assembly of civilian aircraft into a separate production facility. S-80 is now the most complete of all Sukhoj conversion projects.
Many advanced features, combined in a single aircraft, distinguish the S-80 from its competitors:
