Seoul, South Korea (AP). Initial investigation into the December devastating Jeju air disaster in South Korea, the results showed that although both engines supported the bird’s shot, his pilots turned off a less damaged disaster just before his catastrophe. Conclusions that impressed people’s mistakes quickly caused the protests of pilots of lost families and colleagues, accusing the authorities in an attempt to change responsibility for the disaster for the dead pilots.
The South Korean Aviation and Railway Accident Investigation Board initially planned to publicize airplane engine research on Saturday. However, according to government officials and lost families, she was forced to cancel the press briefing in the face of strong protests of the relatives of the accident, which were informed of the conclusions earlier that day.
“If they want to say that their investigation was carried out reliably, independently, they had to provide evidence to support it,” said Kim Yu-Jin, the head of the association who had lost their families. “None of us spare pilots.”
The Boeing 737-800, owned by Jeju Air, landed on his stomach without its own land equipment deployed at the South Korean South Muano International Airport on December 29. He overestimated the running, hidden into the concrete structure and exploded to the flame. It was the mortal catastrophe in the history of South Korean Aviation over decades, killed by all of the 181 people on board except two.
Study signals pilots turned off the wrong engine
Based on a copy of the unpublished briefing report received by the Associated Press, a multilateral research team led by South Korean said it did not find any flaws of airplane engines built by French Safran and GE.
The report states that the carefully examination of the engines, it was found that the right airplane engine suffered more serious internal damage after bird strokes because it had surpassed large fires and black smoke. However, the pilots turned off the left airplane engine, the report said by quoting the probes on the cab on the voice recording device, the flight data recorder and the engine exams.
Earlier, officials said the black Boeing Jetliner box had stopped recording about four minutes before the accident, aggravating the cause of the disaster. The hanging voice recording device and the flight data recording device, quoted in the briefing report, indicate the data stored before the entry stopped.
The report did not say why the pilots turned off the less damaged engine and did not interfere with whether it was a pilot error.
Lost family, fellow pilots beat a probe
Jeju Air and other airlines have lost their family and pilots covered the results of the study, saying that the authorities must disclose the cockpit voice recording device and the flight data recorder.
“We, 6,500 pilots ‘Airlines’, cannot detain our anger against the pretending argument of the Aviation and Railway Herbial Investigation Board that has lost neutrality,” the Korean Pilot Union Alliance said in a Tuesday statement.
The Jeju Air trade union pilots also issued a statement calling for the authorities to provide scientific evidence that the plane had to land normally if it was flying with a less damaged engine.
The latest report focused on engine problems and did not mention other factors that could also be blamed for the accident. Among them is the concrete structure that the plane crashed. It contained a set of antennas called localizers to safely lead aircraft at the time of landing, and many analysts say it had to be made easier with fractured materials. Some pilots say they suspect the government would not want to most and clearly accuse localizers or bird strikes for mass deaths because the Muano Airport directly owns the Ministry of Transport.
The Aviation and Railway Herry Investigation Board and the Ministry of Transport did not propose a public response to criticism. They said they would also not publicly interview an engine study to respect the requirements of lost families.
The AP, who was familiar with the investigation, said the authorities are looking at localizers and other questions, such as whether air traffic controllers handed over the risk of bird strikes to pilots fast enough and what an emergency training for Jeju Air to pilots. The person who asked for anonymity, stating the nature of the sensitive investigation, said the authorities had previously planned to publish the probes after reviewing various issues, but changed the plan and tried to release the results of the engineers who lost the engine. He said the authorities did not intend to take on pilots responsibility for disaster.
The authorities seek to publish the final results of the investigation until June the following, the person said.
Kwon Bo Bo Hun, a dean of College of Aeronautics at the Far East University of South Korea, called the engine research report “clumsy” because it did not reveal the evidence to support his conclusion to the pilots. He said it was only annoyed by the “emotional part of us” because the investigation caused suspicions that it blamed the dead pilots.
A former AP professor at the AP, who has reached AP, said the engine survey report must be “reliable” because it is based on the analysis of the cabinet and flight data records, which “does not lie”. He spoke to the condition of anonymity, indicating the subtle nature of the question.
