AN-140

ANTONOV ASTC has completed testing of the An-140 regional aircraft, intended for passenger and mixed passenger/cargo operations. An-140 is a substitute for the An-24 aircraft which has been operated already for about forty years. On the 25th of April, 2000, CIS Interstate Aviation Committee's Register issued Type Certificate to the An-140 and its derivative An-140-100.

The aircraft enjoys a reputation of being both quiet and economical. With a range of 1,300 miles, the turboprop has a range of 1,300 miles at a cruising speed of up to 575 kph. Priced at $9m each, it is one of the world's cheapest medium-range aircraft. More than 100 Russian and Ukrainian enterprises are reportedly involved in Iran's production of the An-140, with some 80% of parts coming from Russia.

In the beginning of the 3rd millennium, airlines will have to cease using their An-24's because of the aircraft depreciation above all. The An-140 serial delivery since this year will permit airlines to begin their fleet renewal, providing operations all over the regional line network. An-140 aircraft can be operated in the wide range of the airfield heights and climate, in VFR & IFR weather conditions, at day and night. The An-140 aircraft has a high wing arrangement, standard tail configuration and two wing-mounted 3-117V-SB1 turboprop engines. The AI9-3B auxiliary power unit, installed in the rear fuselage section, allows independent aircraft operation from unpaved airfields. A high degree of comfort in the passenger compartment is achieved by selecting the optimum ratio between the compartment volume and that of the auxiliary holds, the low noise and vibration level, improved air conditioning, well-matched lighting and other factors.

The baggage & cargo holds having a total volume of 9.1 3, and a 1.84-ton cargo capacity are arranged in the fuselage rear portion. They are 1.3 to1.5 times more spacious in volume when compared to the respective compartments of other airplanes of the same class. The rough-field capacity landing gear with low pressure pneumatics, and the high-mounted engines preclude propellers and inlet ducts from any damage which may occur due to ingestion of foreign matter at takeoff or landing. Thus, the aircraft can be operated from unpaved, pebbled, glacial and snowbound airfields or areas.

The aircraft is capable to lift cargoes at special pallets in the front part of the passenger compartment upon removal of the front seat rows. There is a cargo door arranged in the fuselage right hand-side for this purpose, and the reinforced floor of the passenger compartment front portion is equipped with an appropriate removable equipment.

Within the period of 1997 to 1999, the N-140 passed the complete cycle of its Certification Test. Three flying prototypes plus an aircraft for the structural on-ground testing were used. The test flights covered a variety of climatic areas and ambient temperatures ranging from minus 55 to plus 45, conditions of high elevated (up to 1,700 m above the sea level) airfields. The first serial An-140 aircraft, produced by Kharkov State Aviation Manufacturing Company of Ukraine, was purchased by the Ukrainian IKAR Airlines of Kiev. The first serial airplanes weremanufactured by AVIAKOR (Samara, Russia) and that of the Iranian HESA Industries, Isfahan.

Antonov ASTC together with their An-140 program partners have prepared the system of Integrated Logistic Support for the aircraft operation which includes the following:

  • supply of spare parts, consumables, maintenance aids and facilities;
  • availability of operation and maintenance publications;
  • training of flight crews and ground personnel;
  • repairs, modifications, various activities connected with maintenance of the aircraft units and assemblies;
  • full-scale engineering support.

The aircraft high reliability, fuel efficiency, long service life and on-condition provisions have to result in the minimum of maintenance and operation expenditures.Development of the new aircraft family like it was in the case of the n-24/26/30/32 derivatives is envisaged. It will include the cargo, administrative VIP, special purpose (ice patrol and fish finder, aerial photography and patrol) airplanes, as well as an extended fuselage version to carry 68 passengers.
