The Yakovlev Yak-40 (Russian: -40; NATO reporting name: Codling) is a small, three-engined jet airliner, the world's first commuter trijet. The maiden flight was made in 1966, and it was in production from 1967 to 1981. Introduced in September 1968, the Yak-40 has been exported since 1970.

Development

By the early 1960s, Soviet international and internal trunk routes were served by Aeroflot, the state airline, using jet or turboprop powered airliners, but their local services, many of which operated from grass airfields, were served by obsolete piston-engine aircraft such as the Ilyushin Il-12, Il-14 and Lisunov Li-2.[5] Aeroflot wanted to replace these elderly airliners with a turbine-powered aircraft, with the Yakovlev design bureau being assigned to design it. High speed was not required, but it would have to be able to operate safely and reliably out of poorly equipped airports with short (less than 700 m or 2,300 ft) unpaved runways in poor weather.[6]

Yakovlev studied both turboprop and jet-powered designs to meet the requirement, including Vertical Take-Off and Landing designs with lift jets in the fuselage or in wing-mounted pods, but eventually they settled on a straight-winged tri-jet carrying 20 to 25 passengers. The engines were to be the new AI-25 turbofan being developed by Ivchenko at Zaporozhye in Ukraine.[7]

Design

The Yak-40 is a low-winged cantilever monoplane with unswept wings, a large T-tail and a retractable tricycle landing gear. The passenger cabin is ahead of the wing, with the short rear fuselage carrying the three turbofan engines, with two engines mounted on short pylons on the side of the fuselage and a third engine in the rear fuselage, with air fed from a dorsal air-intake by an "S-duct", as is an auxiliary power unit, fitted to allow engine start-up without ground support on primitive airfields.[8][9] The three AI-25 engines are two-shaft engines rated at 14.7 kN (3,300 lbf). The engines have no jetpipes, and initially no thrust reversers.[10][11]

The pressurized fuselage has a diameter of 2.4 metres (94 in). Pilot and co-pilot sit side-by-side in the aircraft's flight deck, while the passenger cabin has a standard layout seating 24 to 27 passengers three-abreast, although 32 passengers can be carried by switching to four-abreast seating. Passengers enter the aircraft via a set of ventral airstairs in the rear fuselage.[11][12]

The wing is fitted with large trailing-edge slotted flaps, but has no other high-lift devices, relying on the aircraft's low wing loading to give the required short-field take-off and landing performance. The wings join at the aircraft centerline, with the main spar running from wingtip to wingtip The wings house integral fuel tanks with a capacity of 3,800 litres (1,000 US gal; 840 imp gal). The aircraft has a large fin, which is swept back at an angle of 50 degrees to move the tailplane rearwards to compensate for the short rear fuselage. The horizontal tailplane itself is unswept.[9][13]

The Yak-40 was the first Soviet-built airliner designed to Western airworthiness requirements.[14]

Operational history

The first of five prototypes made its maiden flight on 21 October 1966,[11] with production being launched at the Saratov Aviation Plant in 1967 and Soviet type certification granted in 1968.[9] The type carried out its first passenger service for Aeroflot on 30 September 1968.[13] In the 1972 version, a tailspin was removed. In 1974, new version was introduced, with non-stop flight distance increased. Also, the forward door on the right side of the fuselage changed its place it was located together with the sixth window.

In 1975, the last upgrade of Yak-40 took place the number of cabin windows on the right side changed from nine to eight.

By the time production ended in November 1981, the factory at Saratov had produced 1,011 or 1,013 aircraft. By 1993 Yak-40s operated by Aeroflot had carried 354 million passengers.[15] As well as being the backbone of Aeroflot's local operations, flying to 276 domestic destinations in 1980, the Yak-40 was also an export success. More than this, Yak-40 became the first Russian/Soviet aircraft to get flying certificates from Italy and West Germany. It was demonstrated in 75 countries of the world, including the US, where orders on Yak-40 were made.

A total of 130 were exported to Afghanistan, Angola, Bulgaria, Cambodia, Cuba, Czechoslovakia, Equatorial Guinea, Ethiopia, Germany, Guatemala, Honduras, Hungary, Italy, Laos, Madagascar, Philippines, Poland, Syria, Vietnam, Yugoslavia and Zambia.[9][15]

Cause was possible crew error.[67][68][69]
  • On August 2, 1988, at Sofia Airport, a Hemus Air Yak-40 LZ-DOK crashed on take-off. All civil traffic had been halted minutes before because of the departure of the Bulgarian leader Todor Zhivkov's Tupolev Tu-154. After the delay, air traffic control cleared LZ-DOK for take-off to Varna, asking the crew to expedite their departure. Trying to leave in a hurry, the crew did not set the trim correctly and began their take-off run from the middle of the 3000 m runway. The aircraft failed to become airborne, overran the runway into a ravine and caught fire, killing 29 of 37 on board. The "black box" of the airplane was never found.[citation needed]
  • On August 1, 1990, Aeroflot Flight E-35D, a Yak-40 (CCCP-87453) traveling from Zvartnots Airport, Armenian SSR to Stepanakert Airport struck a mountain 22 km (14 mi) away from its destination killing all 46 on board. The cause was probably pilot error (premature descent).[70][71]
  • On November 7, 1991, Yugavia Flight S-519, a Yak-40 (CCCP-87526), struck Kukurtbash Mountain (14 mi north-northwest of Makhachkala Airport) in poor visibility, killing all 51 on board; the aircraft was overloaded and was designed to carry 32 passengers, not 47.[72][73]
  • On March 27, 1992, another aircraft from Aeroflot Armenia (registration unknown) with 30 passengers and four crew, on an evacuation mission from Stepanakert to Yerevan, was hit after take-off by a MANPADS (reported by a source to be an SA-7) launched by Azeri forces. The missiles damaged one of the plane's engines and there are conflicting reports either forced the pilots to land at Sisian (on Armenian-controlled territory) or made it to Yerevan.[74][75][76]
  • On May 9, 1992, a third Aeroflot Armenia aircraft (CCCP-87532) on evacuation mission from Stepanakert to Yerevan with 30 passengers (refugees and wounded) and three crew, was attacked above Kalbajar District (a now Armenian-occupied part of Azerbaijan) by gunfire from an Azeri Sukhoi Su-25 flown by Vagif (or Vaghit) Kurbanov, an Azeri pilot that had defected with his aircraft a month earlier from Russian forces stationed at Sitalchay. The crew managed to make a gear up land at Sisian airfield. Everyone survived but the plane was written off.[76][77][78]
  • On November 14, 1992, Vietnam Airlines Flight 474 with 31 passengers and crew flying from Ho Chi Minh City-Tan Son Nhat International Airport to the previously civilian Nha Trang Airport impacted obstacles on approach killing all but one passenger. Adverse weather conditions might have been involved (unclear at investigation).
  • On August 28, 1993, a Tajik Air Yak-40 (87995) operating a non-scheduled flight that was grossly overloaded with 81 passengers and five crew members overran the runway on takeoff at Khorog Airport and crashed into the Panj River. The crew were killed and only four passengers survived. The crew may have been forced to overload the aircraft. This is the deadliest accident involving a Yak-40 as well as the deadliest accident in Tajikistan.
  • On February 25, 1994, a Yak-40 (OB-1559) operated by Expreso Aéreo, piloted by two Russians and one Peruvian,[79] struck Mount Carpish six minutes after leaving Tingo María, Peru for Lima. The 31 occupants were killed.[80]
  • On September 26, 1994, a Cheremshanka Airlines Yak-40 (RA-87468) from Krasnoyarsk Airport, Russia to Tura was unable to land at Tura because of bad weather so was diverted to Vanavara. It ran out of fuel due to crew and ATC errors and crashed while attempting an emergency landing on a river, 41 km (25 mi) from Vanavara. All 28 passengers and crew were killed.[81]
  • On October 27, 1994, Rostov Air Enterprise (Donavia) Flight 156, a Yak-40 (RA-88254) was hijacked on October 25 while en route to Rostov from Ashgabad by one man claiming to have a bomb. After reporting the incident the pilot returned to Makhachkala. The hijacker demanded 2 million US dollars and to be flown to Iran. The aircraft landed and some passengers were released, but more hostages were not released until the next afternoon on October 26. By that evening all passengers were released, leaving the hijacker and some of the crew on board. Shortly after midnight on October 27, they too were released. Just before sunrise, as the aircraft was about to be stormed by security forces, the hijacker blew himself up with a homemade bomb. The blast damaged the plane, and it was written off.[82]
  • On November 5, 1994, another Peruvian aircraft (OB-1569) belonging to Amazonic regional airline Servicios Aéreos Amazónicos, that was serving the Trujillo-Saposoa-Juanjuí-Tocache-Lima schedule, crashed into the Saposoa River after overrunning the airstrip during landing. The aircraft either crashed due to heavy rain reported at the time. From the 31 occupants (26 passengers and 5 crew) 5 passengers and 1 crewmen died.[83][84][85]
  • In 1996, two Weasua Air Transport Yak-40s (RA-87290 and RA-87999) were destroyed on the ground at Sprigg Payne Airport after being struck by RPG-7 anti-tank rockets during the First Liberian Civil War.[86][87]
