The Ivchenko AI-14 (Ukrainian: АІ-14) is a nine-cylinder, air-cooled, radial piston engine designed in the Soviet Union to power aircraft.


Its main variant is the AI-14R (АІ-14Р), which underwent state trials in December 1950 and was used in many types of light aircraft. Several thousand were built. There was also an AI-14V variant for helicopters and other applications. The AI-14R is typically used with a two-bladed propeller and is started with compressed air.

Apart from the Soviet Union, a licensed version of the AI-14R, (currently AI-14RA), was produced by WSK-Kalisz in Poland from 1956 until 2007.

The AI-14RF was a variant uprated by Ivan Vedeneyev to 300 hp. Its further development is the Vedeneyev M14P family of engines.

Another modified version is the Czechoslovak Avia M462, which powers the Zlín Z 37 agricultural aircraft.

The Zhuzhou HS-6' was the designation for AI-14 Licence production in China.
