Yakovlev Yak-40

The Yakovlev Yak-40 is a small, three-engined regional transport aircraft.

Built to replace the Lisunov Li-2 (a DC-3 variant) and the Ilyushin Il-14, its main design feature was ease of operation outside major airport service areas. It was equipped with a built-in airstair and capable of STOL operations.

Since the demise of the old Aeroflot, many have been converted from passenger service layout to more luxurious corporate layouts and are in use as corporate and private aircraft.

Most of the Yak-40s in active service fly in the former Soviet Union, but some are flying in Europe, but are rare because of noise restrictions.

Its nickname is 'flying whistle', for the distinct engine sound it makes.
