First flown in 1953, the IL-14 was developed from the IL-12 and is known in the West under the NATO reporting name Crate. Many thousands were produced in the Soviet Union, East Germany and Czechoslovakia (as the Avia 14). The IL-14 basic version with normal accommodation for 28 passengers was followed by the IL-14M and IL-14P. The former has a fuselage lengthened by 1.0m and accommodates up to 32 passengers, while the latter seats 26 passengers, has improved performance and an AUW of 16,500kg. A large number of M and P versions were converted into IL-14T freighters.
