Incident
One hour and 16 minutes after takeoff, while flying in formation with other similar aircraft, the captain informed the formation leader that engines number 1, 2, and 4 had failed. The aircraft left the formation and began a descent in an attempt to divert to Chita-Kadala Airport.
Emergency Landing
Unable to reach the airport, the captain extended the landing gear and flaps and executed an emergency landing in an open field. Upon touchdown, the landing gear collapsed, and the aircraft slid for several dozen meters before coming to rest. A fire erupted immediately.
Destruction and Fatalities
The aircraft was destroyed by the fire. All six crew members on board were killed.
Probable Cause
The investigation determined that engines 1, 2, and 4 failed because the fuel was contaminated by water. Additionally, the crew failed to follow emergency procedures.
