The Antonov An-72 (NATO reporting name: Coaler) is a Soviet/Ukraine transport aircraft, developed by Antonov. It was designed as an STOL transport and intended as a replacement for the Antonov An-26,[2] but variants have found success as commercial freighters.

The An-72 and the related An-74 get their nickname, Cheburashka, from the large engine intake ducts, which resemble the oversized ears of the popular Soviet animated character of the same name.

Design and development

An unusual design feature of the An-72 is the use of the Coandă effect to improve STOL performance, using engine exhaust gases blown over the wing's upper surface to boost lift.

The An-72 first flew on Template:Date2 and was likely developed as a response to the never-manufactured USAF Advanced Medium STOL Transport (AMST) initiated ten years earlier.[3] Produced in tandem with the An-72, the An-74 variant adds the ability to operate in harsh weather conditions in polar regions, because it can be fitted with wheel-skis landing gear, de-icing equipment, and a number of other upgrades, allowing the aircraft to support operations in Arctic or Antarctic environments. Other An-72 versions include the An-72S VIP transport and An-72P maritime patrol aircraft.

Its first flight was made on Template:Date2, but production started in the late 1980s. The powerplant used is the Lotarev D-36 turbofan engine.[4] The An-72 resembles the unsuccessful Boeing YC-14,[5] a prototype design from the early 1970s (design submitted to the United States Air Force in February 1972,[6]) which had also used overwing engines and the Coandă effect.

The rear fuselage of the aircraft has a hinged loading ramp with a rear fairing that slides backwards and up to clear the opening. Up to 7.5 tonnes (7.4 long tons; 8.3 short tons) can be airdropped while it has folding side seats for 52 passengers.

In 2018, six An-72 aircraft were reported to be upgraded for the Russian Aerospace Forces and Navy to carry more fuel and payload for Arctic operations.[7]

Operation

The An-72 has STOL capabilities; its take-off roll is 620 m (2,000 ft) and its landing run is 420 m (1,400 ft).[8] This aircraft was designed to be used on unprepared surfaces; its robust undercarriage and high-flotation tyres allow operations on sand, grass, or other unpaved surfaces.

Accidents and incidents

(As of May 2022), there have been 24 known accidents and incidents involving the An-72 or An-74; of these, the following involved fatalities:[13]

  • Template:Date2— CCCP-74002 attempted to take off from Lensk Airport overloaded with fish. All 13 human occupants died when it crashed 4 kilometres (2.5 mi) from the airport.[14]
  • Template:Date2— An Antonov An-72 chase plane had a mid-air collision while following the Antonov An-70 prototype aircraft during a test flight. The collision caused the An-70 to crash into a forested area, killing all seven An-70 crew members.[15] The An-72 lost a right wing flap,[16] but it was able to return to base safely.[15]
  • Template:Date2— ER-ACF, an Antonov An-72 disappeared on a cargo flight from Port Bouet Airport, Côte d'Ivoire to Rundu Airport, Namibia. The aircraft and its five crew members disappeared without a trace over the South Atlantic. The cause of the incident remains undetermined.[17]
  • Template:Date2— UR-74038 carrying food aid to Chad from Libya crashed in Cameroon, killing all 6 crew.[18][19]
  • Template:Date2— An Islamic Revolutionary Guard Corps Air Force An-72 crashed after takeoff from Mehrabad International Airport in Tehran, killing 37 of the 38 aboard.[20]
  • Template:Date2— An An-72 carrying Kazakhstani border patrol officials crashed in Shymkent, killing all 27 people on board.[21][22]
  • Template:Date2— An An-72 operated for the Air Force of the Democratic Republic of the Congo with 4 crew and 4 passengers crashed in Congo; none survived.[23][24]
