Nizhnetambovskoye

The floatplane departed Khabarovsk on a flight to Aleksandrovsk-Sakhalinski with an intermediate stop in Nizhnetambovskoye, carrying three passengers, four crew members and a load of 460 kilos of mail. About an hour after departure from Nizhnetambovskoye, while in cruising altitude, the pilot noted a leak on the right engine, between cylinders n°7 and 8. Shortly later, the right engine stopped and the crew decided to attempt an emergency landing on the Amur River. At the time of the accident, the water was glassy and upon landing some 700 metres offshore, the airplane crashed, overturned and sank. All four crew members were rescued by fishermen while all three passengers drowned.

The float plane departed Nizhnetambovskoye at 1555LT on the final leg to Khabarovsk on a flight from Aleksandrovsk-Sakhalinsky. The crew did not obtain any weather bulletin for en route and destination prior to takeoff. Also, several instruments such as the variometer, the path finder and the artificial horizon were unserviceable. After passing over Komsomolsk, weather conditions deteriorated with low clouds and the captain decided to reduce his altitude and to continue at a height of 150 metres. Later, stormy weather forced the pilot to lower again his altitude and eventually, he attempted to land on the Amur River. On final, he saw an island and initiated a sharp turn to the left when the left float impacted the water surface. The aircraft cartwheeled and crashed in the river off Malmyzh. A passenger and all three crew members were rescued while six other occupants were killed.

The airplane departed Okha on a flight to Khabarovsk with intermediate stops in Nikolayevsk-on-Amur and Nijnetambovskoye. While descending to Nijnetambovskoye, the pilot encountered marginal weather conditions. Because the visibility was limited, he reduced his altitude to minimum. On final approach, at a height of 50 metres, the right wing failed and detached. The airplane nosed down and crashed in a pasture. All 16 occupants were killed.
