Yakovlev Yak-40

Updated: October 2026 – A small, roundish jet with surprisingly long, straight wings, three engines at the rear and a high T-tail: that is the Yakovlev Yak-40. From the late 1960s the Soviet short-haul jet was meant to replace old propeller aircraft at provincial airfields, often on grass or gravel. More than 1,000 were built, and as one of the very few Eastern Bloc jets it even flew for a West German airline out of Hamburg. Here you will learn how to identify the Yak-40 with confidence, what sets it apart from the Yak-42, Tu-134 and Boeing 727, and where you can still come across it today.

What is the Yakovlev Yak-40?

The Yak-40 is a three-engine short-haul and feeder jet from the Yakovlev design bureau. Until then the company had been known mainly for fighters, sport and trainer aircraft – the Yak-40 was its first jet airliner. The order came in the early 1960s from Aeroflot: the state airline was still flying postwar piston-engine aircraft on its huge regional network and wanted to replace them with a turbine-powered type.

The requirements were tough. The aircraft was to take off and land reliably on short, unpaved runways of sometimes less than 700 meters and in bad weather. It also had to work independently of ground equipment, since many provincial airfields had neither start carts nor passenger stairs. The result was an aircraft that differs in many ways from typical jets of its time: straight wing, three small engines, built-in auxiliary power unit, its own stairs.

The first flight took place on October 21, 1966, and five prototypes were built. Series production started in 1967 at the Saratov aircraft plant on the Volga, and Aeroflot began scheduled service on September 30, 1968. By 1981, according to common counts, 1,011 aircraft were built, with some sources giving 1,013. The successor in the program was the much larger Yak-42. Yakovlev today belongs to the Russian group United Aircraft Corporation. How the Yak-40 fits into the overall history of Eastern Bloc aviation is covered in the article Soviet airliners.

Technology: built for grass strips and provincial airfields

The most important decision was the choice of engines. Three turbofans of the Ivchenko AI-25 type, each with around 14.7 kN of thrust, power the Yak-40. The then-new engine was developed at the Ivchenko design bureau in Zaporizhzhia, Ukraine. Two sit in nacelles on the sides of the rear fuselage, the third in the tail itself. It draws its air through an inlet on the back of the fuselage in front of the fin, and an S-shaped duct leads it downward to the engine. Three engines instead of two gave reserves in case of a failure, especially on takeoff from short fields.

The straight, unswept wing is the second core element. There are no slats on the leading edge; only slotted flaps on the trailing edge serve as high-lift devices. The Yak-40 achieves its short takeoff and landing distances mainly through its low wing loading: lots of wing for little weight. According to German-language data sheets, a takeoff roll of around 340 meters and a landing roll of around 360 meters are enough. The downside: with a cruising speed of around 510 to 550 km/h, it was hardly faster than modern turboprops.

Two details provide independence from the ground. In the tail sits an auxiliary power unit (APU) of the AI-9 type, which starts the main engines and supplies the cabin with air – at a time when this was by no means standard on small airliners. What exactly an APU does is explained in the article APU, ground power and PCA. And under the end of the fuselage a built-in staircase folds out, through which passengers board at the rear. There was no thrust reverser at first; later the middle engine received a reverser.

Two pilots and a flight engineer work in the cockpit. The cabin is tiny for a jet: in the usual three-abreast seating with an aisle, 24 to 27 passengers fit, and in dense four-abreast seating up to 32. With the seat rows folded up, according to German-language sources up to 2.5 tonnes of freight can be loaded.

Version	Features	Note for spotters
Yak-40	Base version for 24 to 32 passengers	By far the most common variant
Yak-40D	Longer range through more fuel	Hardly distinguishable from the outside – check the registration
Yak-40K	Freight and combi version with a large cargo door, built from 1975	Look for the large cargo door on the side of the fuselage
Yak-40EC / Yak-40V	Export versions for customers outside the Soviet Union	Hardly distinguishable from the base version on the outside
Salon versions	VIP cabins for governments and military	Often in air force or government colors
Testbeds	Special aircraft, for example for engine and measurement technology	One-offs with striking add-ons

A curious case from more recent times: since 2021, a Yak-40 in Russia has served as a flying testbed for an electric drive – with a propeller at the front in the nose, driven by a superconducting electric motor. So if you see a photo of a Yak-40 with a propeller on the nose, it is not a photo montage.

The features that are enough to identify it

The Yak-40 can be pinned down in three glances – it has a silhouette that exists nowhere else.

When the aircraft is on the ground, the folded-out rear stairs confirm the type for good. The cabin windows are strikingly large and roundish for such a small jet. The nose is short and blunt, without a glazed navigator station – unlike the Tu-134, which has a glass nose in its early versions. You will find more on reading engine arrangements under How to recognize engines.

Yak-40, Yak-42, Tu-134 or Falcon 50?

The Yak-40 shares rear engines and a T-tail with several types. The finder helps you narrow it down.

With the Boeing 727, the Yak-40 shares the principle of a third engine in the tail, fed through an S-duct. The 727, however, is a much larger medium-haul jet with strongly swept wings. The same goes for the British Hawker Siddeley Trident and the Soviet Tu-154. How to tell small jets apart in general is shown in the article Recognizing regional jets.

On the road in the West: General Air and Italy

What sets the Yak-40 apart from almost all other Soviet airliners: it was deliberately offered and demonstrated for export to the West. It is considered the first Soviet airliner to be certified in Italy and in the Federal Republic of Germany. In total the type went to around 20 countries.

For spotters in Germany, General Air is especially interesting. The airline was based in Hamburg, with Hamburg Airport as its base. In June 1972 the first of eventually five Yak-40 joined the fleet. The aircraft were used on domestic German routes, including between Hamburg, Kassel, Lübeck, Düsseldorf, Frankfurt am Main, Munich and Saarbrücken. On February 19, 1975, D-BOBD crashed in a botched landing at Saarbrücken Airport and was written off as a total loss. In January 1976 General Air filed for insolvency – ending the German chapter of the Yak-40 in scheduled service.

In Italy, several smaller airlines flew the type, including Aertirrena, Alinord, Avioligure and Cabado. No significant fleets arose from that in the West; the Yak-40 remained an episode there. Its heyday was in the Eastern Bloc and in friendly states in Africa, Asia and Latin America – from Cuba to Vietnam to Afghanistan.

Workhorse in the East and government jet

At Aeroflot the Yak-40 was the backbone on short regional routes for decades, especially where larger jets like the Tu-134 could not land. After the breakup of the Soviet Union the aircraft went to the many new airlines of the successor states; the type is long gone from today’s airline landscape around the Aeroflot Group.

Small, rugged and with its own stairs: that also made the Yak-40 a popular government and military transport. Numerous air forces used it, including those of Poland, Hungary, Bulgaria and Czechoslovakia and later the Czech Republic; the governments of the Czech Republic and Slovakia also flew the type. North Korea ordered eleven aircraft in 1978 for VIP transport. How to track down state aircraft today is explained in the guide Spotting government aircraft.

A Polish government Yak-40 gained sad notoriety on April 10, 2010: it carried journalists to Smolensk and landed there about an hour and a half before the Tupolev Tu-154 of the Polish president, which crashed in rapidly deteriorating weather. The Yak-40 crew had previously informed the Tu-154 crew by radio about the very poor visibility.

Like any type with such a long service life and demanding operating profile, the Yak-40 also has a long accident list. Its first fatal accident occurred in 1970 with Aeroflot. According to the Aviation Safety Network database, there were more than 90 hull losses by November 2025 – with over 1,000 aircraft built and many operations at basic airfields.

Who still flies the Yak-40 today?

The active fleet has shrunk sharply. In July 2019, according to a widely used count, 22 aircraft were still registered with civil operators. The Russian Vologda Aviation Enterprise still had five in its inventory in early 2025, and in Kazakhstan Zhezkazgan Air reported one aircraft in early 2020. Among air forces, the World Air Forces 2026 annual report lists no Yak-40 anymore.

How many of these actually fly in October 2026 cannot be said with certainty from open sources. When in doubt, check the registration in a fleet database. The prefix reveals the origin: RA- stands for Russia, UP- for Kazakhstan – more under Country codes on aircraft.

Spotting tips: how to get a Yak-40

Realistically there are three ways: the last civil operators, exhibits in museums and historic photos from archives. A few Yak-40 stand in museums and as monuments, mainly in Eastern Europe and the successor states of the Soviet Union. Which aircraft stand where and whether they are accessible changes – check directly with the museum before any trip. How to search for unusual types in a planned way is shown in the article Spotting rare aircraft. And if you would like to sit in a classic yourself once, you will find inspiration under Flying rare aircraft types as a passenger.

Common mix-ups and how to rule them out

Conclusion

The Yak-40 is an idiosyncratic classic: a jet meant to behave like a bush plane. Straight wings, three small engines, its own APU and stairs made it independent of well-developed airports – and a workhorse on countless provincial routes of the Soviet Union. That it even flew domestically for a Hamburg airline in the 1970s makes it especially interesting for spotters here. Today it has become rare, but its silhouette is not forgotten.
