EAS .4011.000 is designed to equip helicopters Mi-8, Mi-8MTV, Mi-8AMT, MI-171, MI-172 and their modifications, which are based at the shoreline of open and closed water areas and perform flights above the water surface. The helicopter’s EAS guarantees landing and stay afloat for the time required for deployment of swimming aids and for the crew and passengers leaving the helicopter in case of emergency landing on the water surface.

The emergency drive system consists of main and nose cylinders and 2 gas-fill units. The main balloons are fixed on the main landing gear poles, the front ones – on the fuselage bow. One gas-filling unit consists of two balloons mounted on one frame. The gas filling units are installed in the left cargo sash on the seat box or on the starboard side of the 5H hose.
