The initial results of an investigation into the disastrous Jeju air accident of December revealed that, while both engines of the aircraft had maintained bird attacks, its pilots reduced their pilots just before their accident. The discovery, which vested human errors, quickly protested with bereaved families and fellow pilots, accusing officials of trying to move the dead pilots responsibility for the disaster.
South Korea’s Aviation and Railway Accident Investigation Board initially planned to promote the results of the investigation of the aircraft engines on Saturday. According to government officials and bereaved families, the crash victims were forced to cancel their press briefing in front of strong protests by relatives.
“If they want to say that they were investigated in a reliable, independent manner, they should have come up with evidence that supports their clarification,” Kim You-Zin said, Kim You-Jin, head of a association of an association, said. “None of us is angry with the pilots.”
Boeing 737-800, run by Jiju Air, landed on his stomach on 29 December without land gear deployed at South Korea’s southern Mun International Airport. It exposes a part, slipped into a solid structure and burst into flames. It was the deadliest disaster in South Korea’s aviation history in decades, killing two out of 181.
Investigation signal pilots shut down a wrong engine
According to a copy of an unpounted briefing report received by the Associated Press, the South Korean -led multilateral investigative team stated that it did not find any fault in the engines of the aircraft manufactured by Safran and GE of France.
The report said that the intensive examinations of the engines found that the right engine of the aircraft caused more severe internal damage after the bird attacks as it was surrounded by large fire and black smoke. But the pilots shut down the left engine of the aircraft, stating that the cockpit voice recorder, flight data recorder and probe on engine exams.
Officials earlier said the Boeing Jetliner’s black box stopped the recording about four minutes before the accident, complicating the investigation into the disaster. Cockpit voice recorders and briefing report refers to the data stored before the recording recording quoted in the briefing report.
The report did not explain why the pilots shut down the low-defined engine and reduced it, saying whether it was an error by the pilots.
Condolences, fellow pilots slammed the investigation
Surprised families and pilots in Jeju Air and other airlines provoked the conclusions of the investigation, saying that officials should disclose the cockpit voice recorder and flight data recorder.
Korean pilot Unions Alliance Alliance said in a statement on Tuesday, “We cannot include our anger against the emergent arguments by 6,500 pilots, aviation and railway accident inquiry boards in civilian airlines.”
The union pilots of Jiju Air also issued a statement to urge the authorities to offer scientific evidence to show the aircraft, if it fly with a low damaged engine, it should be normally landed.
The latest report focused only on engine issues and did not mention other factors who could also be convicted for accidents. Among them is the concrete structure in which the aircraft crashed. It placed a set of antennas, which was designed to safely guide the aircraft during landing, and many analysts say it should have been made with more easily breaking materials. Some pilots say they suspect that the government would not want to blame the attacks of local people or birds for mainly and primarily large -scale deaths as the Muan Airport is under the direct management of the Ministry of Transport.
The Aviation and Railway Accident Investigation Board and the Ministry of Transport have not given any public response to criticism. He said that they would not publicly discuss the engine test to honor the demands by bereaved families.
A person acquainted with the investigation told AP that the authorities were looking at the local people and other issues such as air traffic controllers rapidly relaxed the danger of bird attacks for the pilots adequately relaxed and what emergency training the pilots gave to the pilots. The person who had requested oblivion, citing the sensitive nature of the investigation, said that the authorities planned to promote the results of the investigation after reviewing various issues earlier, but changed the plan and tried to release the results of the engine investigation at the request of the bereaved families. He said that the authorities have not intended to take responsibility for the pilots for the disaster.
The officials targeted to publish the final results of the investigation by next June, the person said.
But the Dean of Aeronautics College at the Far East University in South Korea, Quon Bo Hun, called the government’s planned announcement “Anari” because it did not disclose the evidence that supported its discovery on the pilots. He said that it only “harasses the emotional parts of us that the people who died of the investigation have full fault.”
Professor, who joined a former Transport Ministry arrived by AP, said the engine test report should be “reliable” as it is based on the analysis of cockpit voice and flight data recorders who “do not lie”. He spoke on the condition of anonymity, citing the delicate nature of the issue.
