Aviamotornaya (Russian: Авиамото́рная) is a Moscow Metro station in the Lefortovo District, South-Eastern Administrative Okrug, Moscow, Russia. It is on the Kalininsko-Solntsevskaya Line. The station was opened on 30 December 1979.
The station is built in a three-vault configuration 53 metres (173 feet) underground. The central hallway contains a sculpture made out of anodised gold pyramids and tetrahedra. The architects of the station are A.F. Strelkov, V.I. Klokov, N.I. Demchinsky, J.A. Kolesnikov, and E.S. Barsky. The theme of Aviamotornaya is aviation and flying. The columns holding up the ceiling are glazed in a light marble tone. The floor is made up of granite plates coloured in different shades of grey. The wall at the end of the central hallway is faced in a metal sculpture. There are decorations mentioning and detailing the main constellations.
Escalator Accident in 1982:
The escalators of the station caused a significant disaster on the Moscow Metro on February 17, 1982, that killed at least 8 people. As evening rush-hour approached, escalator #4 was turned on at 16:30 Moscow time. As the first commuters began to use it to descend, a poorly-attached step came loose, completing the cycle of coming all the way down and then back up on the opposite end of the chain. At 17:00, as it passed the upper mechanism, it got stuck and deformed the upper working gears and rods.
This broke the clutch between the driving gears of the engine, and the thread, now free to move in any direction, began to accelerate from the weight of the passengers. Automatically the engine was immediately turned off and the brakes were applied. However, the standard working brakes lacked the strength to stop the momentum of the thread (heavily laden with passengers at this rush-hour), or even to reduce its acceleration.
