The Ilyushin Il-114 (Russian Илью́шин Ил-114) is a Russian twin-engine turboprop airliner designed for local routes. In the Antonov An-24 class, it first flew in 1990. Altogether, 20 Il-114s have been built.[3]

Production of the Il-114 was terminated in July 2012, with the sixth and last aircraft delivered to Uzbekistan Airlines on 24 May 2013. The decision to end production adheres to the Uzbek government's decision to convert the Tashkent factory to other production lines (namely structural units, household purpose products, spare parts for cars and agricultural equipment), despite Russian interest in keeping the production line and a reportedly high demand prospect for the aircraft. This has translated in an October 2013 announcement by a plant representative, that production is to be resumed after the factory solved financial matters and also due to the interest of a "Russian party".[4][5]

Design and development

In June 1986, the Ilyushin OKB began work on a replacement for the Antonov An-24, large numbers of which remained in service with Aeroflot. The Soviet Ministry of the Aviation Industry set down requirement for the An-24 replacement, including the ability to carry 60 passengers over a range of 1,000 kilometres (620 mi) at a speed of 500 kilometres per hour (310 mph), while using much less fuel than its predecessor and retaining the ability to operate out of poorly equipped airfields with unpaved runways.[6][7][8] Development of the new aircraft was expected to be relatively simple, with first flight programmed to take place in 1989 and service entry in 1992.[7]

Ilyushin's design, the Il-114, is a low-wing, twin-turboprop monoplane, with an airframe mainly constructed of metal, with composite materials used for non-structural parts. The aircraft is powered by two Klimov TV7-117S turboprop engines driving six-bladed propellers. Undercarriage is a retractable nosewheel undercarrige, while double-slotted trailing edge flaps are fitted to the wings.[9][10] Unlike previous Soviet airliners, which had a large flight crew, the Il-114 is flown by a crew of two, who are provided with electronic flight instruments.[11] Up to 64 passengers are accommodated in the aircraft's cabin, with passenger's baggage carried in compartments at the front and rear of the cabin rather than under the cabin floor.[9][12]

The first prototype made its maiden flight from Zhukovsky Airfield on 29 March 1990.[13] Development was slowed by technical problems (including delays with the TV7-117 engines), and by organisational and financial problems associated with the Break-up of the Soviet Union, with the Il-114 to be built at the Tashkent Aviation Production Association in soon to be independent Uzbekistan. The second prototype did not fly until 24 December 1991. This second prototype crashed, killing seven of nine people aboard, on 5 July 1993, causing the Russian government to withdraw funding from the Il-114, although the OKB continued development with its own money.[14][15] The Il-114 finally received airworthiness certification on 26 April 1997.[16]

Il-114-100 of Uzbekistan Airways in 2008

Since Vyborg was forced to shut down in July 2010, Uzbekistan Airways remains as the sole operator of the type. As of January 2014 no further orders have been placed for the Ilyushin 114. Uzbekistan Airways currently operates four of their seven aircraft of the type, with three being stored or used as backup in Tashkent.

In winter 2013/2014 the aircraft is scheduled for the following routes:[17]

Though the aircraft is not scheduled for other flights, following ad hoc changes it is also (though rarely) flown to other destinations in Uzbekistan. This also includes international connections: though these are no longer scheduled for the Ilyushin 114, the aircraft is sometimes used ad hoc on flights between Tashkent and Ashgabad as well as Bishkek. Uzbekistan Airways frequently changes aircraft prior to flights in order to allow for optimal usage of aircraft space in relation to actual demand.

From 2005 an Il-114 was converted into a flying testbed by Agat and Radar-MMS. With a capability to loiter for 14 hours, Agat and Radar-MMS have turned it into an advanced-technology MPA demonstrator. Il-114 RA93001 aircraft demonstrated the transmission of telemetry and targeting data in real time using a wide-band secure datalink using the Kasatka rescue and targeting complex during IMDS’2015 maritime show. This Il-114 has a FLIR under the nose, a magnetometer in the tail section, a semi-automatic sonobuoy dispenser, and 2 pylons under the fuselage for sensor pods or Kh-35 anti-ship missiles. On the right side of the fuselage, a GSh-2-23 twin barrel 23-mm rapid fire cannon pad can be installed, with conformal Metric-band antennas on both sides. This aircraft has two radars, one (KS-9) working in metric waveband (range up to 50 km) and the other (KS-1 or Zarya) in centimetric waveband (range 300 km). An additional antenna is in an underbelly dome for 360-degree coverage.[18]

After the events in Ukraine in 2014, Russia is looking to modernize the Il-114. It will replace the Ukraine-made An-140T that was selected before, to refresh the Russia Air Force's medium transport aircraft fleet of An-26s and An-72s. Ilyushin is also offering the Maritime Patrol version of the aircraft to the Russian navy that can patrol for up to 10 hours. It can be armed with 1.5 tons of sonobuoys and depth charges, with modern search-and-attack radar, magnetic anomaly detector and a thermal imager. The Il-114MP is intended to supplement and may then replace the ageing Il-38.[19]

President Putin has ordered a study into resuming Ilyushin Il-114 turboprop production at the Aviakor plant in Samara, southeast of Moscow, with results of the assessment due in September 2014.[20] Possible improvements can include updated engines and avionics, rear cargo ramp/door, structural strengthening, digitization of engineering drawings. China may be interested in the modernized Il-114.[21][22][23]

The Russian naval service chief Maj. Gen. Igor Kozhin announced that the Russian navy is looking for “a modern and suitable universal platform” to replace the aging Il-20/Il-38 MPA fleet. Selection will be made in the period of 2015-16. A Maritime Patrol version of the Il-114 twin-turboprop airliner most likely will be a candidate. According to Georgy Antsev, general director and designer for Morinformsystem-Agat, “In my view, the Il-114 is the best choice for the Russian navy”. Companies promoting the Il-114 as an MPA include Agat, Ilyushin, Radar-MMS and others.[18]

Ilyushin Company Chief Designer Sergey Gromov announced that they will develop a version of Il-114 aircraft fitted with ski and wheel landing gear for the Arctic Region. The development program will produce three Il-114 aircraft by 2020 with Gidromash/Hydromash JSC (Nizhny Novgorod). It will be designated Il-114-300 and will be produced using only Russian-produced components. Four versions of Il-114-300 would be developed including a passenger version by 2019; Cargo and Arctic versions derived from the passenger version, and a Maritime Patrol Aircraft, whose prototype was showcased at Army-2015 forum.[24]

Russia’s United Aircraft Corporation (UAC) expects the Russian government will decide later on in 2015 to whether allow the state-backed aerospace group to build a new 50-to-70-seat passenger version of the Ilyushin Il-114. At Moscow's MAKS airshow on August 26, UAC president Yuri Slyusar said he favors building the new Il-114-300 model but awaits the Kremlin’s endorsement.[25]

The Il-112V, being developed from the Il-114 airliner, will replace Russia’s aging fleet of Antonov An-26s, as the LVTS (Russian acronym for Lightweight Military-Transport Aircraft). The Ilyushin Il-112V tactical airlifter for the Russian air force will make its maiden flight in the summer of 2017, according to Yuri Slyusar, president of United Aircraft Corporation (UAC).[26]
