Mil Mi-14SP crash near Aniva Bay, 11km off Sakhalin, Sakhalin Oblast, Russia

The amphibious Mi-14SP, built in 1981, was taking part in a joint Russian-Japanese search and rescue exercise in Aniva Bay off southern Sakhalin, simulating a response to an oil spill and aid to stricken shipping. It ditched in the Sea of Okhotsk after losing power. Attempting to take off again from the water in a heavy swell, the helicopter tipped onto its nose, the main rotor blades struck the water and shattered, and it rolled inverted and was destroyed. Five crew and an eight-member civil aviation rescue team were aboard. All thirteen were recovered, several by Japanese divers from a vessel taking part in the exercise, and survivors were landed at Korsakov. Three were seriously injured; the pilot, who suffered a spinal injury, was flown out by Mi-8 and later died. Russian transport prosecutors opened criminal proceedings, working on the assumption of a technical fault in the airframe or its Klimov TV3-117M engines. The sequence was filmed from the Japanese vessel.
