Narrative:
An anti-submarine warfare helicopter SH-60J of Japan Maritime Self-Defense Force (JMSDF) was apparently crashed into the sea of Japan at 90 km west-southwest of Cape Tappi, Aomori prefecture. Radar and radio contact with the Seahawk were lost at 22:48 LT, and distress signals by a flare gun and the radio distress signal from FDR were received thereafter. One of four occupants, a sonsor operator, was rescued without injury a half hour later. The rescued person had occupied a starboard seat behind PIC at the time of the accident. He/she suddenly felt an impact and sea water came into the cabin. Escaping from the right emergency exit window, the sensor operator flushed the flare gun. Remaining three occupants are still missing as of 29th August. The FDR and wreckage (radome, parts of upper and lower fuselage, tail rotor blade(s), main rotor blade(s)) of SH-60J were retrieved separately. The accident helicopter was on a night-time landing/takeoff training at Destroyer Setogiri (DD-156) of JMSDF, and apparently crashed at about 10 km left and back of Setogiri.
The FDR of SH-60J is designed to be released automatically by an accident or a ditching, float on the water and send the radio distress signal. These functions apparently functioned correctly in this accident.
On Thursday 7 September 2017 the three missing crew members were still missing. They are deemed to have died in the crash.
