The Ilyushin Il-62 (NATO reporting name Classic) is a Soviet long range jet airliner. Conceived in 1960 by Ilyushin, it first flew in 1963 and entered Aeroflot service on 15 September 1967 with an inaugural passenger flight from Moscow to Montreal. The Il-62 was the Soviet Union's first long-range jet airliner as well as the first to be put into service by several other countries. It was also the first Russian pressurised aircraft to have a fuselage with non-circular cross-section (3.8 x 4.1m width X height) and ergonomic passenger doors, and the first Russian jet with six-abreast seating (the earlier turbo-prop Tu-114 also had this arrangement) and international-standard navigation lights.

The Soviet Union/Russia was the largest operator, and over 80 were exported with more being leased by Russian-sphere and western airlines. The Il-62M became the longest-lasting version in its class of long-range airliners, with some examples having been in operation for three decades. Special VIP (salon) and other conversions were also developed. The successors of the Il-62 include the wide-bodied Il-86 and Il-96 which were made in smaller numbers than the Il-62 and not widely exported.

Development

The Il-62 replaced the fast turboprop Tu-114 on long range routes. As the Tu-114 was just entering service when the Il-62 was on the drawing board, Ilyushin had time for an unhurried design, test, and development programme. This was useful, since the Il-62 did call for significant development.

The Il-62 and the British Vickers VC10 are the only commercial airliners with four engines fitted in twinned/paired nacelles by the sides of, and beneath, a "T" shaped empennage (T-tail), although the Lockheed JetStar business jet shares this configuration. In the case of Ilyushin, the configuration was dictated by TsAGI, the Soviet Union's aerospace agency, since Ilyushin's design bureau lacked the resources to engage in configuration studies. Although offering an efficient clean wing, the aft-engined T-tail configuration is now known to have a number of serious drawbacks. It is tail-heavy, requiring a large and heavy empennage because the tail moment arm is short. Worryingly, aerodynamic wash (shadow) from the wing blankets the tail when the nose is pitched up (at "high angles of attack"). This calls for complex and (in the 1960s) unreliable automatic stall recovery systems such as "stick shakers" and "stick pushers."

Early aircraft (prototypes, pre-production and initial production aircraft) display an evolution from thin or thick kinked leading inboard edges to the ultimate thick and straight 1966 shape. The characteristic "dog tooth" also moved until fixed before production began. The engine installation also evolved, with the engines' longitudinal axes canted by 3 degrees from the horizontal; thrust reversers were added to the outer engines, and the entire installation was slimmed down as production began.

The prototype was grossly underpowered. Its intended NK-8 engines were not ready and small Lyul'ka R-7PB turbojet engines had to be installed temporarily. The prototype with the R-7PB engines (registered СССР-06156) first flew on 3 January 1963. It crashed after clipping a perimeter fence during the development program. The production Il-62 was powered by the originally intended rear-mounted Kuznetsov NK-8-4 engines. The first Il-62 powered with NK-8 engines (registered СССР-06153) first flew in 1964.

Rossija' (Russian State Transport Company) Ilyushin Il-62 RA-86467 at Munich Airport

The Il-62M variant (first flight in 1971, introduced in 1973) has more powerful and quieter Soloviev D-30KU engines and a fin fuel tank. Beneath the skin, the Il-62M has simpler and lighter single-slotted flaps and incremental aerodynamic improvements. Most important of these was the addition of spoilerons (spoilers or wing-mounted airbrakes which act as ailerons by differential deployment in cruising flight) and the ability to use idle reverse thrust in flight during the final approach so as to shorten the landing run. Nearly all examples in service today are Il-62Ms. In 1978, the Il-62M was further developed to seat up to 198 passengers and carry some two tonnes (4,400 lb) more payload and/or fuel than the Il-62M.

A version designated Il-62MK was designed as a much modified medium-range machine, though it never reached high production and was dropped from the programme by 1978 (although Germany operated two examples). Other versions were also planned, some "stretched" to seat up to 250 passengers and others suited to small airfields. None of those reached the detail design stage. No civil/military or military developments are known.

The Il-62 has a conventional landing gear with an additional trademark lightweight landing gear strut at the rear of the fuselage[1] which extends when the aircraft reaches its parking position. Aircraft with rear-mounted engines are usually tail-heavy when sitting empty on the ground, and to prevent the aircraft from tipping up on its tail, various devices are used for supporting the tail - from simple "pogo stick" fixed struts on small aircraft, to light-weight extendable struts (Il-62). Aircraft like DC-9, MD-80/90 or B727 use an airstair door under their tail which serves the dual purpose of a tail support as well as an extra door for passenger loading.

The Il-62 is the largest airliner with manual flight controls, using steel cables and rods, pulleys, aerodynamic and weight balances, and trim tabs. There are also indications that the Il-62 has a forward-mounted tank for water ballast. This may be used when the aircraft flies empty or lightly loaded. If this is a fact, it would rank the Il-62 alongside other airliners that use ballast, notably the French Caravelle and the Soviet Tu-154. Due to the rear mounted powerplants, the wings are aerodynamically clean, and takeoff and landing aids are employed without the disturbing effect of engine nacelles, resulting in free airflow over the dorsal wing surface. Thus the aircraft can fly through air turbulence of 16–18 m/sec without affecting its stability (Thiel, 2001).

Another key Il-62 trademark is the "saw tooth" ("dog tooth") on the wing leading edge. This prominent feature acts as an aerodynamic fence, vortex generator (without which the wings would be almost vortex-free), and fixed leading edge droop/slat/flap. It ensures vice-free behaviour at high angles of attack and assists efficient long-range cruise. The saw tooth removes the need for hydraulic controls, stick shakers, and stick pushers. Interestingly, later models of the VC10 (for British United Airways and Ghana Airways) also adopted this feature, in their case closer to the wing tips.

Early N-K 8-4 engined Il-62's were underpowered and suffered from indifferent performance as well as engine fatigue/overheating, sometimes leading to false fire alarms whereby the crew might mistakenly shut down paired engines (because failure in one could affect the adjacent engine as well as fuselage damage). Flying on only two paired engines would, however, render the aircraft unbalanced and difficult to control. Subsequent modifications to the Il-62 and the VC10 (which had a similar engine arrangement) largely retified this problem. There were two fatal Il-62 losses due to engine-failure, and both occurred with aircraft owned by the Polish airline LOT (which had also leased a large number of Il-62s from Aeroflot and Tarom). The higher fatality (183) was a fully-laden Il-62M LOT Polish Airlines Flight 5055 on 9/5/1987 which experienced a rear fuselage fire that possibly went unnoticed by the crew (hence their decision not to land at one of two nearby airports). Earlier, LOT had also lost an unmodified (early version) N-K 8-4 powered Il-62 Flight 007 on 14/3/1980 with 87 fatalities. Powerplant failure of this type was extremely rare (engine bearing wear is normally detected by turbine vibration tests during maintenance) and these two accidents involving different engine types (but same engine # 2) was a fatal crash-rate some 30 times higher than the Il-62 average (2.8% vs 0.092%). Following the 1987 loss, LOT introduced turbine vibration tests with more frequent inspections, and modified its aircraft by adopting the dual flight control system and deleting the auxiliary engine-pod fuel tanks.

Special Il-62 conversions

Several special conversions were made to the basic Il-62, the main ones being the Il-62 and Il-62M salon VIP versions used by heads of state, and the Il-62M airborne command aircraft (just one example) used by the Russian government (Gordon et al, 2004). Although the Il-62 had been introduced during Khrushchev's time, it was during the Brezhnev era that Ilyushin was asked to develop the salon versions which have been used by Russian leaders ever since right up to the Putin years (during which time both Il-62 and Il-96 aircraft were used in combination). The VIP examples were fitted with conference rooms and rest areas, rooms for the retinue, and service personnel and bodyguards, while the secure communication equipment enabled contact with Moscow and other cities from any part of the globe. Examples were also delivered to other countries including Czechoslovakia, Germany, North Korea, Sudan and the Ukraine.

The single airborne command Il-62M (RA-86570) was customised for the emergency response agency EMERCOM to provide evacuation transport for Russian citizens from foreign countries and act as airborne command post for these and other emergency situations (Gordon et al, 2004). It operates in conjunction with a fleet of Il-76, Il-76TD waterbombers, AN-72 and helicopters which have operated in some 60 countries and saved 50,000 lives since the agency was created in 1994. Apart from basic interior changes, RA-86570 features hush-kitted engines and Honeywell electronics with global communication ability via satellite, and an Inmarsat system. The aircraft was used as a command post during the combat of forest fires in the Far East, when dealing with the Chechen terrorist attack in Kaspiysk when an apartment building was blown up, and to bring Russian Vice-Minister of Foreign Affairs to Sharjah in 1997 and from there collecting the crew of an Il-76 freighter that had escaped from the Taliban militia in Afghanistan.

Design

The Il-62 is a conventional all-metal low-wing monoplane of riveted sectional semi-monocoque construction to fail-safe design principles (a structure designed so that failure of one major member does not cause immediate failure of the whole). Its service life was initially set at 30,000 flight hours and subject to extensions and curtailments according to the quality of service procedures, inspection and manufacturer's bulletins. The aircraft features pressurised cabin and freight holds, duplex all-mechanical flight controls, though with twin electric motors for tailplane incidence control; hydraulic nosewheel steering, landing gear and tail strut actuation, and wheel brakes. The Il-62M has spoilers and lift dumpers which extend automatically upon landing and are hydraulically operated. Control surfaces include a variable-incidence tailplane with dynamically and weight-compensated elevators with trim tabs, triple-section tabbed ailerons (outermost for low speed and innermost for high speed) which are interlinked with a torsion bar, spoilerons (Il-62M), spoilers and lift dumpers, and pneumatically-actuated thrust reversers on the two outboard engines (the reversers are flight-rated on the Il-62M).

27V AC electrics are used throughout with a TA-6 auxiliary power unit (a turbine generator which supplies electric power and air conditioning on the ground) in the lower tailcone plus backup lead-zinc batteries.

The aircraft uses conventional hot air de-icing using engine bleed air. Its sea level is equivalent to 2,400 m (8,000 ft) above mean sea level and thereafter reducing to the equivalent of 2,400 m (8,000 ft) to cruise altitude. It was originally built with no automatic oxygen masks; emergency supply comprises hatrack-housed oxygen bottles and masks for manual distribution to passengers by cabin crew. Since 1997, most aircraft have been retrospectively fitted with automatic oxygen supply systems with drop-down masks.

Its avionics include a Polyot-1 automatic flight control system (a "super autopilot," able to be programmed with a set route which it can fly without human intervention but under constant flight crew monitoring; ICAO Cat. 1 approaches standard, Cat. 2 optional), Doppler navigational radar replaced by triplex INSS (Inertial Navigation System Sets) on Il-62M after 1978 and by GPS (Global Positioning System) navigation sets on many aircraft after 1991, triple VHF and HF flightdeck radios, automatic direction finders, Soviet and Western instrument landing system receivers, vertical omindirectional radio range and radio beacon receivers, duplex radio altimeters, automatic radio transponders, a full ICAO-standard navigation lights fit, cabin tannoy and intercom systems. Soviet/Russian and Warsaw Pact sovereign examples are additionally fitted with triplex "Odd Rods" (NATO code name) IFF (identification friend or foe) air defence transponders identifiable by three closely spaced short aerials.

Emergency evacuation systems include inflatable life rafts and manually extendable canvas evacuation slides. Most aircraft are now retrospectively fitted with emergency floor lighting strips and some aircraft equipped with automatically inflatable evacuation slides. Fire extinguishers are sited in engine nacelles, flightdeck compartment, cabin crew rest areas and toilets.

The Il-62 offers accommodation for up to 198 passengers in a single-class layout, seated six-abreast at 84 cm (33 in) seat pitch in two cabins separated by a vestibule, galley/pantry and cabin crew rest area. There are three toilets, forward, midships, and aft. It has a buffet/bar and a further cabin crew rest area in a vestibule forward, with a further optional cabin crew rest area aft. Typical mixed-class accommodation ranges between 128 and 144, seated four or six abreast. A first class compartment is optionally sited aft of forward entry door or just forward of midships entry door, with an economy compartment further forward in the latter case. "Skycot" fitments are located in hatracks, while later Il-62Ms (1978 onwards) feature enclosed hatracks. Customer-optionable interior fitments. No in-flight entertainment systems are available except a publi-address system that may be coupled to an open-reel or audio cassette player. Individual aircraft were experimentally fitted with television sets for Soviet-standard videotape entertainment during the 1970s. Some aircraft were retrospectively fitted with Western in-flight entertainment (solely audio) systems after 1991.

Operational history

After the introduction of the Il-62M, Aeroflot (the largest operator of the plane) gradually upgraded its old Il-62s with the D-30 KU Soloviev powerplant, which, coupled with engine housing and other modifications, greatly reduced the chance of contagious engine damage. By mid 1973, the airline was operating some 60 Il-62s, and by 1989 this had increased to 165 (Il-62 and Il-62M) (Thiel, 2001). The Il-62M had a dispatch rate with Aeroflot of 97% with some examples logging as many as 17 flight hrs/day, and it was described as the most reliable type in the fleet at that time (Gordon et al, 2004). It set several international records in its class, mostly exemplifying a range capability far in excess of the conservative Aeroflot calculations applied in Soviet times. Some of these records were set by an all-woman crew of five captained by Iraida ("Inna") Vertiprahova. With 10 tonnes of freight, the Il-62M had a maximum range of 10,300 km compared to 9,412 km for the VC10 carrying the same weight. With a 23 tonne payload, the Il-62M range was 8000 km, compared to 6,920 km for a Boeing 707 with maximum payload.

The Il-62 was said to be well regarded by pilots and passengers alike, especially for its strong directional stability in high turbulence (although landings are sometimes bouncy), smooth cruising ability and very quiet interior due partly to engine placement (Gordon et al, 2004). A typical single isle configuration for long distance Aeroflot examples was: first class (2-abreast) 3 rows, business class (3-abreast) 4 rows, economy class (3-abreast) 17 rows (Thiel, 2001). In this configuration, the central isle in business and economy classes was quite narrow. One of the drawbacks of the original Il-62 design was the lack of a cargo bay roller transfer system, which necessitated manual loading of pre-packaged baggage and cargo thus making preparation of the aircraft rather slow (a cargo/baggage conveyance system is standard on the Il-62M). Conversely, there is relatively easy access to all serviceable mechanical components including the engines (Thiel, 2001) whilst the plane's thrust reversal capabilities allows reverse taxiing without the need for tow-vehicles. Powerplant overhaul intervals vary between specifications and maintenance procedures. Czech Airlines operated one Il-62 on a proving basis up to 3000 hrs between overhauls, which was well beyond the recommended (and their usual) intervals which were nearer 2000 hrs (Gordon et al, 2004) although Interflug were able to designate up to 5000 hrs with their service facilities. Later examples of the Il-62M are still in regular commercial service, mostly with countries of the former Soviet Union, but also with China (most Soviet airliners have been retired in China), Libya and North Korea. The type also sees continuing service as a VIP/head of state transport.

Although the plane's safety record does not equal that of new generation airliners, there were no fatal accidents involving any version Il-62 between 1989 and 2009 in the two decades during which the highest number of planes were in service (Thiel, 2001). The safety level of the Il-62M compares favorably with comparable planes of its generation, most of which are no longer in civilian use. Its total hull loss rate (7.7%) is much lower than those of the Boeing 707 (16.4%) and DC-8 (14.9%), and near to that of the VC10/Super VC10 (7.8% if one excludes three examples destroyed by terrorists) although that aircraft was only in civilian service for 16 years vs 36 years for the Il-62M (as at 2010). Several Il-62/M accidents over the first decades of operation mainly involved runway overruns or aborted takeoffs. The braking system employed the reverse thrust of the outer engines only, and if for some reason one or other failed to engage, the aircraft could become difficult to steer for an unprepared pilot. In seven takeoff or landing accidents there were no fatalities, a testament to the high level of structural integrity (and in two cases with landing-related fatalities [CCCP-86470 and UP-16208] these were due to the aircraft colliding with structures near the runway [tower and concrete wall, respectively]). The Il-62/M fuselage features a strengthened hull with 'ski' keel allowing for an undercarriage-up emergency landing. However, the trade-off for the reinforced airframe is the relatively high fuel consumption (greater than a Boeing 707 for example) and some airlines such as Interflug modified their planes in an effort to reduce fuel (Thiel, 2001).

A sideline to the Il-62 story concerns alleged industrial espionage. As the Il-62 was developed at about the same time as the VC10, to which it bears a marked external resemblance, British Cold War commentators implied that the VC10 design may have been copied by dubbing the Il-62 the "VC10-ski." (Thiel, 2001). However, no evidence of this has ever been presented and, as noted above, later model VC10s adopted some Il-62 wing design features. There are significant differences between the two machines in any case, as the Russian type is larger, lifts a greater load, covers a longer range, and is suited only to developed airports vis-a-vis the British type's adaptability to "up-country" bases. Unlike the VC10, the Il-62 uses conservative technology, such as mechanical control surface linkages, and is an entirely civil machine, whereas the VC10 was designed to double as an airlifter as well as a military freighter. The Il-62 found more buyers and was built in larger numbers than the VC10 (292 vs 54), and was still in civilian service (as at 2010) whereas the VC10 has long been retired from that role (in 1966 BOAC described the aircraft as uneconomic and asked for government subsidies to continue its operation. At the end of its civilian career some VC10s were used by the UK airforce in support roles). China and Czechoslovakia were two countries that considered buying the VC10 (for CAAC and Czech Airlines, respectively), before opting for the Il-62 (see VC10: Sales and airline service).

Operators

Civil operators

Air Koryo Il-62M

Some 42 airlines have operated the Il-62 and its variants since civilian service began in 1967. The Soviets did not export the Il-62 until initial Aeroflot needs (rapid replacement of Tu-114s on international services) had been met. First exports were in late 1969 to CSA Czechoslovak Airlines. The pattern was similar with the Il-62M, whose first export (to Cubana) was delayed until 1979, six years after Aeroflot service entry. Among Eastern Bloc nations, only Bulgaria and Hungary did not operate the Il-62 series, although the Hungarians briefly leased one pending Boeing 767 services in 1990. This was due, among other reasons, to heavy anti-Ilyushin lobbying by Tupolev in the former country and to commercial considerations in both countries whose airlines preferred to concentrate on short and medium range routes.

Germany, Czechoslovakia and Cuba were amongst the largest foreign customers for the Il-62. The former East German airline Interflug claimed to have been the largest non-Russian operator (but only counting planes purchased, rather than purchased plus leased) and they owned 24 examples; 21 in civilian service and three for airforce use (later transferred to the united German airforce), including six Il-62, 16 Il-62M and two rare Il-62MK (after unification, seven Interflug IL-62s were on-sold to Uzbekistan which later also bought the three airforce examples). Czech Airlines (formerly Czechoslovak Airlines) operated 21 planes between 1969 and 1997, including 15 Il-62 and six Il-62M, of which 15 were registered under the famous CSA 'OK jet' designation, and six were leased from Aeroflot. Cuba operated 28 planes (11 Il-62 and 17 Il-62M), of which nine were leased from Aeroflot and 19 were owned by Cubana which became a long-term operator (after 2000 it refurbished its remaining IL-62Ms for its international routes although most had been retired by 2010). Poland operated 23 Il-62 and Il-62M, including aircraft leased from Aeroflot and Tarom.

Current and past operators include Aeroflot, Air India (lessor), Air Ukraine, Alim Airlines, Alpha Airlines, Aviaenergo, Air Koryo, Centrafricain, CSA Czechoslovak Airlines, Cubana, Dalavia, Deta Air, Domodedovo Airlines, East Line Airlines, Interavia Airlines, Interflug, Jetline, KAPO, Air Kokshetau, KrasAir, Libyan Arab Airlines, LOT Polish Airlines, Malév Hungarian Airlines (lessor), EgyptAir, Mavial Magadan Airlines, Mekong Air International, Moscow Airways, New Millennium Air, Quadrotour-Aero, Rossiya Russian Air Transport Company, SAT Airlines, TAAG Angola Airlines, Sayat Air, TAROM, Tretyakovo, VIM Airlines, Uzbekistan Airways, Yana Airlines, and CAAC. From 1970, Air France and Japan Air Lines wet-leased a number of Aeroflot Il-62s for long-haul services, and from 1971, KLM Royal Dutch Airlines operated nine Aeroflot-registered Il-62s for the Moscow-Amsterdam route (these planes wore joint Aeroflot/KLM markings).

By September 2009 a total of only 38 Ilyushin Il-62 aircraft remained in active service, only one of which is the original series aircraft operating with Russian Air Force whilst others are M or MK-series aircraft. Current operators include: Air Koryo (4), Deta Air (3), and Cubana (1). Some other airlines and governments also operate small numbers of the type.[2] In Russia all planes were removed from scheduled passenger operations in autumn 2008 due to a severe economic crisis affecting major operators Interavia Airlines, Dalavia and Domodedovo Airlines. As a result of these events Rossiya became the largest operator, but it uses Il-62 for government service only.

Military operators

The aircraft has seen military use with the air force of East Germany (DDR [GDR]) and later the united Germany (one Il-62MK and two Il-62Ms) and is believed to have been operated by air forces of several other countries, namely Cuba, Gambia, Georgia, Libya, North Korea, Russia and Ukraine. It has also been used as an emergency response aircraft (Russia), and as a personnel or head-of-state transport by several nations, including Ukraine, Sudan, Russia (eight examples) and Czechoslovakia, the government of which used an Il-62 (OK-BYV) and three Il-62Ms between 1974 and 1996.

Hull Losses

Since its first flight in 1965, there have been 12 accidents resulting in fatalities during civilian service, namely: 9 crashes, 2 landing runway overruns and 1 aborted takeoff (fatalities of the last three having resulted from collisions with structures near the runway). The complete list of incidents include 8 of Il-62M (a total of 25 incidents/accidents in ASN database, 14 of which were Il-62M,[3] including 24/4/1998 [4] and 20/4/2008) [5].

As of Feb 2010 there had been 23 hull losses from all causes including prototype testing, fires, runway overruns, navigational errors, and non-operational incidents, 48% of which did not involve fatalities [6] Within the group of comparable airliners (Il-62/Il-62M, VC10/Super VC10, Boeing 707, DC8) the Il-62M had the lowest hull loss rate.

There were no fatal accidents involving any version Il-62 between the years 1989 and 2009.

Date Registration Location Fatalities Brief description
25 February 1965 СССР-06156 Zhukovsky, USSR 10/10 First prototype clipped a perimeter fence during max take-off weight testing, with loss of 10 test crew
16 June 1972 SU-ARN Almaza AB, Egypt 0/59 Landed on wrong airport and overran runway. No fatalities
14 August 1972 DM-SEA East Germany 156/156 Burning air escaping from an unsecured air-con coupling melted electrical insulation and caused a short circuit that ignited inflammable fluid in the cargo bay. After losing elevator function, the crew decided to return to Berlin but were unaware of the fire which eventually destroyed the tail section rendering the aircraft uncontrollable
13 October 1972 СССР-86671 Sheremetyevo, USSR 174/174 Crashed in a lake about 1 km short of the runway during the third attempt to land at night in poor weather conditions. The airport ILS navigation system was inoperative at the time of the accident
23 March 1973 B-2002 China n.d. Unknown
20 August 1975 OK-DBF Near Damascus, Syria 126/128 A particularly unfortunate accident due to language missunderstanding between the control tower and the CSA crew which resulted in an incorrect altimeter being set. Preparing to land at Damascus at midnight, the crew believed the airport to still be at a far lower altitude, and the aircraft flew into the ground 17 kms short of the runway, leaving just two survivors
27 May 1977 СССР-86614 Havana, Cuba 1+68/70 Hit power transmission lines whilst landing from incorrect approach
14 March 1980 SP-LAA Warsaw, Poland 87/87 Engine #2 failed after full thrust on missed approach from New York to Warsaw. Debris punctured the fuselage causing damage to engine #1 and loss of rudder control. Reason: engine material fatigue. The Polish singer Anna Jantar was killed in this tragedy
06 July 1982 СССР-86513 Near Moscow, USSR 90/90 After departing Sheremetyevo bound for Senegal, the crew noticed engine overheating warning lights so the pilot shut down the paired engines and turned around to return to the airport. The aircraft became difficult to control with just two engines and crashed in a field. Investigations later showed that the warning lights had been a false alarm.
29 September 1982 СССР-86470 Luxembourg 14/77 Reverse thrust of engine #1 failed on landing. Pilot failed to steer aircraft effectively and it veered off the runway and hit a water tower
1 July 1983 P-889 Labé, Guinea 23/23 A CAAK-registered Ilyushin Il-62M crashed in the Fouta Djallon mountains mear Labé on a charter flight from Sunan International Airport, North Korea to Conakry International Airport, Guinea.[7]
09 May 1987 SP-LBG Warsaw, Poland 183/183 Engine #2 burst during initial climb 25 min post-departure, causing damage to adjacent engine and a fire in the tail. The captain may have believed the fire extinguished because rather than land at Gdansk Airport or the Modlin airfield, he turned around to return to Warsaw (EPWA) airport (which had better emergency facilities) and dumped half the fuel (unconfirmed reports claim that Modlin denied the aircraft permission to land). During the return flight the fire caused loss of control and subsequent crash close to Warsaw airport. The aircraft is reported to have flown 7000 hrs and almost 2800 hrs since its previous engine overhaul. Reason: engine bearing fatigue
17 June 1989 DDR-SEW Berlin, East Germany 1+21/113 Crew aborted take-off after a locking bolt which had been left in position disabled the elevators and rudder. When instructed to apply reverse thrust, the flight engineer mistakenly switched the engines off and the aircraft ran off the runway without becoming airborne
3 September 1989 CU-T1281 Havana, Cuba 45+126/126 Soon after taking off during a tropical storm, the aircraft was caught in downdrafts and struck navigational aerials and a hillside before crashing into a residential area

Il-62 "Lady Agnes" at Gollenberg

The Il-62 was the first long-range jet airliner to be put into service by several nations, and some retired examples have been converted into museums and other uses in countries such as the Czech Republic, Germany, Austria, Cuba and China (Thiel, 2001). The best known example was the Il-62 "DDR-SEG" from the former East German airline Interflug. On 23 October 1989, DDR-SEG was intentionally landed on a 900m short grass airfield of a hilltop Stölln/Rhinow in a famous but potentially dangerous and dusty maneuver. Fire trucks and ambulance crews were positioned on hand for the landing but were not needed. The jet is used to commemorate the site of the fatal crash of Otto Lilienthal (1848–1896) at the Gollenberg hill. Nick-named "Lady Agnes" after Lilienthal's wife, it is now a museum with the fuselage divided between the Lilienthal collection and a popular wedding registry.[12]
