Variants Tupolev Tu-134

The Tupolev Tu-124 (NATO reporting name: Cookpot) was a 56-passenger short-range twinjet airliner built in the Soviet Union. It was the first Soviet airliner powered by turbofan engines.[1]

Design and development[edit]

Developed from the medium-range Tupolev Tu-104, the Tu-124 was meant to meet Aeroflot's requirement for a regional airliner to replace the Ilyushin Il-14 on domestic routes. Resembling a 75% scaled-down Tu-104, the two were hard to tell apart at a distance but it was not a complete copy of the Tu-104. The Tu-124 had a number of refinements, including double-slotted flaps, a large centre-section airbrake and automatic spoilers. Unlike the Tu-104, the wing trailing edge inboard of the undercarriage was unswept.[2]

The Tu-124 had a drogue parachute to be used in an emergency landing or landing on a slippery surface and had low pressure tires for operation from unpaved airfields.[3][4] As on the Tu-104 the engines were installed in the wing roots, but the turbofan engines used less fuel. The installation of the engines close to the fuselage allowed vibrations to be more readily transmitted to the cabin, which reduced passenger comfort, and also reduced the fatigue life of the wing assembly.[citation needed]

The standard seating of the basic version was 44 seats. The first of two prototype, SSSR-45000 (C/N 0350101) made its first flight from Zhukovsky airfield on 24 March 1960. The second prototype, SSSR-45001 (C/N 0350102), followed in June 1960. Two other airframes served as a static test cells. Testing was successful, and the aircraft entered production at Factory 135 at Kharkov, Ukraine, replacing the Tu-104 in production.[3][5] Deliveries to Aeroflot began in August 1962, with the type operating its first scheduled passenger service, between Moscow and Tallinn in Estonia, on 2 October 1962.[6]

Operational history[edit]

Aeroflot was impressed with the flight performance of the Tu-124 and used it on domestic routes from the end of 1962.

Aeroflot Tupolev Tu-124V in 1965

The improved Tu-124V, which could seat 56 passengers instead of the 44 of the original model, and which had increased range and maximum takeoff weight, came into service in 1964. An Aeroflot Tu-124V was exhibited at the 1965 Paris Air Show. Despite the aircraft's low purchase price (stated as $1.45 million in 1965) and low operating costs,[7] few were exported, with Československé Státní Aerolinie (ČSA) and the East German airline Interflug being the only airlines other than Aeroflot that bought the Tu-124 new, although ČSA sold its surviving Tu-124s to Iraqi Airways for use on VIP flights in 1973. Interflug used its three Tu-124s as an alternative to the Ilyushin Il-62, when the Il-62s were grounded due to mechanical issues. All three were sold back to the Soviet Union in 1975.[citation needed]

Three airframes were completed in 1966 in a VIP configuration, and designated Tu-124K. However, Aeroflot never placed them into service, and they were purchased by the Indian Air Force.[citation needed]

A number were also sold to military users, including the Soviet Air Force, which used them as navigational trainers, and to the Chinese Air Force.[3][8]

A total of 164 Tu-124s were built.[9] Issues with the safety of the Tu-104 affected the fate of the Tu-124, although the reliability of the Tu-124 was slightly better. Production ended in 1965 and Aeroflot decommissioned its last twelve Tu-124s on 21 January 1980. The Tu-124 continued in operation for some years with the Soviet Air Force and in Iraq, but all aircraft were withdrawn before and in 1990, The ones in Iraq military and Iraqi Airways were destroyed in early 1990s during the Gulf War.[citation needed]

Several Tu-124s have been preserved. One is in the museum of the Kharkiv State Aircraft Manufacturing Company (formerly the Tu-124 manufacturer Factory 135), another is in China's Datangshan aviation museum in Beijing, another at the Central Air Force Museum at Monino outside Moscow. A Tu-124K is on display at New Delhi Airport and next to the State Museum at Lucknow Zoo.[10] A sixth one is located at Ulyanovsk Aircraft Museum located in Ulyanovsk Oblast Russia.[citation needed]

Competition within the COMECON[edit]

The German Democratic Republic attempted to compete within the COMECON trade bloc with its own four-engined design called the Baade 152. The design was unsuccessful, leading Interflug to buy a rear-engined development of the Tu-124, the Tupolev Tu-134.[citation needed]


The first production variant. International demand was small, as most foreign airlines were waiting to buy the improved Tupolev Tu-134
Three prototypes with D-20P-125 engines, built in 1963
VIP configuration operated by the militaries of Iraq and China, and by the Indian Air Force

Accidents and incidents[edit]

A total of fifteen Tu-124s were written off in crashes during the type's operational career; another two aircraft of Iraqi Airways were destroyed on the ground during the Gulf War.[11]


21 August 1963
Aeroflot Flight 366, a Tu-124 (CCCP-45021), ditched in the Neva River in Leningrad (now Saint Petersburg) after both engines failed due to fuel exhaustion while the crew was preoccupied with landing gear problems; all 52 on board survived.[12]
8 March 1965
Aeroflot Flight 513, a Tu-124 (CCCP-45028), stalled and crashed shortly after takeoff from Kuybyshev Airport, killing 30 of 39 on board.[13]
11 November 1965
Aeroflot Flight 99, a Tu-124V (CCCP-45086), crashed on the frozen Lake Kilpyavr after the pilot mistook lights near Murmansk Airport for the runway threshold lights, killing 32 of 64 on board.[14]
13 June 1966
An Aeroflot Tu-124 (CCCP-45017) overran a wet runway on landing at Minsk-1 International Airport and was written off; no casualties.[15]
27 July 1966
Aeroflot Flight 67, a Tu-124V (CCCP-45038), went into a dive over Zaporizhzhia Oblast after flying into a storm at 7,200 m (23,622 ft). The crew were able to regain control at 2,800 m (9,200 ft) and landed safely at Simferopol, but one passenger died (of 90 on board) and several more were injured during the incident. The aircraft was repaired and returned to service, but was lost in the crash of Aeroflot Flight 5484 in 1979.[16]
7 March 1968
Aeroflot Flight 3153, a Tu-124 (CCCP-45019), crashed on takeoff from Volgograd Airport after the crew accidently activated the spoilers, killing a crew member; all 44 passengers survived. The spoiler switch had been poorly placed on the control column, allowing the pilot to hit it by accident.[17]


29 January 1970
Aeroflot Flight 145, a Tu-124V (CCCP-45083), struck a hillside while on approach to Klipyavr Airport, Murmansk; of the 38 on board, five died on impact and another six died in the freezing temperatures while waiting for rescue.[18]
18 August 1970
CSA Flight 744, a Tu-124V (OK-TEB), landed wheels-up at Kloten Airport after the pilot, preoccupied with a cabin pressurization problem, failed to hear the command to lower the landing gear; all 20 on board survived. The gear warning system alarm had been turned off.[19]
2 September 1970
Aeroflot Flight 3630, a Tu-124 (CCCP-45012), crashed near Dnepropetrovsk (now Dnipro) following an unexplained loss of control, killing all 37 on board.[20]
9 July 1973
Aeroflot Flight 5385, a Tu-124V (CCCP-45062), suffered an uncontained failure of the right engine shortly after takeoff from Kuybyshev Airport. Debris from the engine penetrated the fuselage, killing two passengers and injuring another four. The crew began an emergency descent and the engine was shut down. Panicking passengers moved to the front of the cabin, causing the center of gravity to move forward, but flight attendants were able to get the passengers seated and the aircraft was able to land safely at Kuybyshev. The aircraft was repaired and returned to service.[21]
20 November 1973
An Aeroflot Tu-124V (CCCP-45031) overran a snow-covered runway on landing at Kazan Airport; no casualties.[22]
