The Self-Defense Forces have found what appears to be the fuselage of a missing SDF helicopter on the seabed about 100 meters below the ocean surface north of Irabu Island, Okinawa Prefecture.
The Thursday night search by a Maritime Self-Defense Force vessel also discovered what appear to be bodies in the fuselage-like object, according to sources connected to the government. It is thought that the wreckage contains the bodies of the crew and other personnel who were aboard the helicopter when it went missing.
The site of the wreckage is close to where the Ground Self-Defense Force UH-60JA multipurpose helicopter disappeared from radar April 6 shortly after takeoff from Miyako Island. What is believed to be the fuselage is heavily damaged, according to the sources.
As the flight recorder and main parts of the helicopter have yet to be recovered, if what appears to be the fuselage is retrieved, it likely will help in determining the cause of the accident.
According to the sources, sonar on the MSDF minesweeper Etajima detected the object on Thursday night. After using an underwater camera, the MSDF confirmed the object appeared to be a fuselage. What appeared to be bodies were also visible inside the wreckage.
The SDF on Friday began to use saturation diving so that divers can reach the about 100-meter depths to conduct closer inspections. Divers first adapted their bodies to the water pressure in equipment of the submarine rescue ship Chihaya. They were scheduled to descend to the seabed in a capsule that is capable of maintaining a high-pressure state and then conduct activities outside the capsule. After confirming the condition of the object, the SDF will look into possible retrieval methods and other matters.
So far, 22 fragments believed to be from the missing helicopter have been recovered. These include a part of an aircraft door and a fuel tank. A helmet and an unused folded emergency lifeboat were also found.
The helicopter had taken off from Miyakojima Sub Base at 3:46 p.m. on April 6 and disappeared from radar at 3:56 p.m. in airspace about 18 kilometers northwest of Miyako Island.
The 10 personnel aboard the helicopter included Lt. Gen. Yuichi Sakamoto, 55, the leader of the GSDF's 8th Division, which is responsible for defense and security in the southern part of Kyushu. Sakamoto had assumed the position in late March, so the helicopter was likely on an aerial reconnaissance mission to confirm geographical features of islands in the area.
The accident has been affecting wider SDF operations. The GSDF has grounded 40 helicopters of the same type.
