History
The development of a new all-metal transport and passenger aircraft began at the Civil Air Research Institute in the early 1930s. The new aircraft was created by the French designer Andre Lyavil invited to the USSR. The plane was a monoplane with a low wing area of 72 square meters. Two M-17F engines located on the planes developed 730 horsepower each. The chassis is not removable in special aerodynamic fairings and the smoothest fuselage. The aircraft, which received the designation ZiG-1 (named after the Goltsman plant, where it was to be manufactured, model 1), had a cabin for 14 passenger seats, or could carry cargo weighing up to 1300 kilograms.
After testing, the ZiG-1 was recommended for production under the designation PS-89. By this time, the Goltzman factory was renamed the aircraft repair plant number 89, hence the new designation of the aircraft: the passenger plane of the plant number 89. The first two prototypes were built in 1935-36. The first of them crashed in a plane crash on November 27, 1935 - when tailing was accelerated to a maximum speed of 50 m Killed all six people on board. Presumably, tail plumage was the cause of the disaster.
The second instance under the designation PS-89 passed flight tests in February-March 1937. Flight performance was lower than design and lower than achieved in 1935. It was noted that the aircraft has insufficient track stability, and as the fuel is consumed, the center of mass is significantly shifted back. The PS-89 was nevertheless accepted for mass production, but operation was allowed only in simple weather conditions and with a maximum load of 10 passengers, not 12.
Six production cars that received the tail numbers L-2140, L-2141, L-2142, L-2143, L-2144, L-2146 were built from 1937 to 1938 . All of them were transferred to Aeroflot and operated flights Moscow - Simferopol , as well as to Sverdlovsk , Kharkov , Kiev , Orel , Astrakhan . At least one of these aircraft, the L-2142, was used as an evacuation aircraft in the Soviet-Finnish War .
The operation of the PS-89 aircraft by the civil air fleet ceased in 1941 in connection with the outbreak of World War II . These aircraft have proven themselves positively. One of the aircraft, L-2146, starred in the Soviet film "Everyday Life" ( 1940 ).
