French Airline Investigation Committee "Concerns about Black Box Damage Under 50 Meters Water Pressure"
Ministry of Land, Infrastructure and Home Affairs Questions, Applicants Authorities Issue a "Rapid Black Box Recovery"
Focus on Search … Plan to Discuss Rescue of Black Boxes "
French Aircraft Accident Investigation Committee (BEA), a manufacturer of fire helicopters that crashed on the sea near Dokdo last month, told the Ministry of Land, Infrastructure and Transport of the Accident Investigation Committee. I'm worried about serious damage to the black box that remains. "
The black box, which reveals the cause of the accident, is believed to be within the tail wing of the accident helicopter. Search officials found tail swings 78 meters south of Dokdo's eastern island during the fourth day of the incident, but have failed to lift them on the 1
BEA's letter to the Accident Investigation Committee stated that "in the case of an unintentional black box over 50 m deep, deep exposure to the sea can cause data damage due to water pressure." It is necessary. "
The Accident Investigation Committee also sent a BEA request to the search authorities, such as the coastal police, in the morning to request an immediate rescue. An official from the Department of Land, Infrastructure and Transport said: "BEA requested the collection of the black box and sent a second letter of cooperation to the search authorities to get the black box as soon as possible." It is necessary equipment to analyze the cause of accidents. "
Bea is an authority participating in investigations of French air accidents occurring abroad as well as all air accidents occurring in French territories and airspace. At present, four organizations are participating in the investigation into the cause of Dokdo's accident helicopters, including the two countries' investigative committees, the helicopter manufacturers Airbus and the engine manufacturer Safran. They are conducting a basic investigation on the helicopter's fuselage, but they must have a black box to examine it. The helicopter's aircraft body has been moved to the hangar at the Ministry of Land, Infrastructure and Transport and is investigating the cause of the accident. / Yonhap News “/>
The Accident Investigation Committee believes that the helicopter may have crashed due to external factors such as device or wind defects, but it is difficult to predict until the black box has recovered. As requested by the BEA and the Ministry of Land, Transport and Maritime Affairs, search authorities, including the maritime police, are expected to review the helicopter's lift time.
But we did not think about the time to lift the swing wing (black box), he said. "As long as I got a letter from the Accident Investigation Committee, I would discuss the recovery of the black boxes."
An underwater investigation into the Sun Seascape was found approximately 600 meters south of Dokdo Island. The search authorities then lifted the fuselage three days later. A missing person in the fuselage was lost during the rescue process, but was reinstated five days later.
