Casualties: Fatalities: 7 / Occupants: 9
Component Affected: AircraftAircraft
Category: Accident
A Li-2 aircraft experienced a significant flight deviation during a nighttime flight from Moscow to Ust’-Kamenogorsk. Due to a failed radio compass and adverse weather conditions, the aircraft diverted to Kurgan, but failed to locate the airport, resulting in a 120 km off-course deviation and insufficient fuel to reach Sverdlovsk. The aircraft subsequently ran out of fuel, leading to a forced landing in heavy snowfall near Omutinskaya railway station in the Tyumen region, resulting in the deaths of all five crew and two passengers.A Li-2 aircraft experienced a significant flight deviation during a nighttime flight from Moscow to Ust’-Kamenogorsk.

Description

The Li-2 operated on a flight from Moscow to Ust’-Kamenogorsk. During the leg from Sverdlovsk to Petropavlovsk, the aircraft deviated from the prescribed flight path at night with the wind being stronger than forecast. En route the radio compass failed and the Petropavlovsk Airport was closed due to bad weather. The crew decided to divert to Kurgan but as contact with the airport could not be established in time they decided to return to Sverdlovsk. In the meantime the aircraft had strayed 120 km off course and the crew realised that fuel would not be sufficient to reach Sverdlovsk. It was decided to head for Petropavlovsk, but failed to locate the airport, while being in fact 215 km north-east of Petropavlovsk Airport. As the aircraft ran out of fuel, a forced landing in heavy snowfall became inevitable. The aircraft landed wheels-up in a snow-covered field 10 km west of Omutinskaya railway station, Tyumen region and broke up. All 5 crew and 2 of the 4 passengers were killed.
