The An-140 is a twin-engine turboprop regional airliner developed to replace the aging aircraft An-24/26 and Yak-40 which have been in service for many decades. It can carry 52 passengers or 6 tons of cargo at a speed of 533 km/h over a distance of 2650 km. The aircraft is equipped with two TV3-117VMA-SB2M turboprop engines. The first prototype first flew on September 17, 1997. In 1999 the aircraft was produced in small numbers by the Ukrainian aircraft factory in Kharkiv (Kharkov State Aircraft Manufacturing Company “KSAMC”). A total of 35 aircraft were delivered. The production of the aircraft was discontinued in 2016.

In addition to Ukraine, the aircraft was exported to Russia, Azerbaijan and Iran. In 1994-95 Iran acquired the rights to jointly produce the An-140 aircraft (the IrAn-140 is manufactured under license based on the An-140).
As of 2023, the remaining aircraft are operated until their resources are service depleted.

The An-140 is powered by two TV3-117MA-SB2M turboprops engines power 5000 h.p. on take-off, driven by 6-bladed Aerosila SV-140, constant-speed fully feathering reversible propellers (curved sword-shaped). The propeller diameter is 3720 mm, the weight 196 kg and their maximum rotation at 1200 rpm/min.
For autonomous starting of the power plant is carried out by an auxiliary power unit type AI9-3B or TA-14 which is located in the tail of the aircraft.
