Yakovlev Yak-40

This small Soviet jet was one of the first regional jets, already designed in the 1960s. Meant as replacement for the Ilyushin Il-14 and Lisunov Li-2 the Yak-40 Codling (NATO code name) is able to operate from small airfields with grass runways. To this extent it has large span straight wings with a significant dihedral. The main landing gear has big single wheels on each leg. The Yak-40 has three engines of which two are attached to the rear fuselage. The third engine is placed in the rear fuselage, with an S-shaped duct leading to the air intake on top of the fuselage, in front of the tail. Passengers enter the cabin via an airstair door under the rear fuselage. There is an additional but smaller door behind the cockpit. The cabin has round windows. Also typical for the Yak-40 are the two landing lights hanging from the nose, when they are in use.

Typical for the Yak-40 are the big main landing gear wheels under the large straight wings. Also note the round cabin windows.

The Yak-40 is the smallest aircraft with three jet engines at the rear of the fuselage and a T-tail.

Different versions

The different versions of the Yak-40 can be recognised by amongst others

  • the presence of a cargo door
  • the presence of a turboprop engine in the nose
  • the presence of pylons under the wings

Details will be added later.

Confusion possible with

Dassault Falcon 900

The Falcon 900 is roughly of the same size as the Yak-40 and also tri-jet, but is clearly different because it has swept wings, double wheel landing gears and a cruciform tail. Also the exhaust of the centre engine extends beyond the rudder. 

Yakovlev Yak-42

yak 42

This is the (much) bigger brother of the Yak‑40, of the same company. Several elements of the Yak‑40 remains, such as the cockpit and cabin windows, and the tail layout. But as said it is much bigger, has swept wings, four wheel bogeys on each main landing gear leg and separate fan exhaust on the engines.
