Jeju Air Disaster: NTSB and Boeing Begin Investigation at Muan Airport

A U.S. government and aircraft manufacturer investigation team has arrived at the scene of the Jeju Air passenger plane disaster at Muan International Airport in South Korea and begun its investigation. According to the Ministry of Land, Infrastructure, Transport and Tourism and the aviation industry on the 31st, two experts from the National Transportation Safety Board (NTSB) and two Boeing officials began an investigation at the accident site that morning. The investigation team reportedly entered the country through Incheon Airport the previous afternoon and immediately moved to the area near the scene. A joint investigation will be conducted with investigators from the Korea Ministry of Land, Infrastructure and Transport’s Aviation and Railway Accident Investigation Committee. Under international civil aviation agreements, aircraft accident investigations must be initiated by the country where the accident occurred. The right to participate belongs to the country where the aircraft operates (South Korea), the country where it was manufactured (USA) and the country where the fatality occurred (South Korea and Thailand). The Thai government will not participate in the investigation into the accident. NTSB experts will first assess the condition of the aircraft wreckage and its current state of dispersal at the scene, and will collect evidence, including searching for remaining parts to find clues to the cause of the accident. This stage is not expected to take long. This will then be followed by the analysis of evidence gathered during the evidence collection phase and data secured from the aircraft’s black boxes. This process can take at least several months and possibly even several years. Meanwhile, it was confirmed that the flight recorder (FDR), one of the black boxes that was moved to the Gimpo Airport Testing and Analysis Center the previous afternoon, had part of its exterior damaged and the connector that connects it to the analysis computer was missing. The other black box, the cockpit voice recorder (CVR), is relatively intact. The FDR records the aircraft’s three-dimensional flight route and the operating status of each unit of equipment. This is the most important piece of information for investigating the circumstances of the accident. The CVR stores conversations between the pilot and co-pilot in the cockpit, communications with air traffic control agencies, and sounds indicating the aircraft’s operating status and warning sounds. The FDR is partially damaged, so it must first be determined whether data analysis is possible. Aviation experts analyzed that by checking the black box, it will be possible to confirm that the plane attempted a belly landing four minutes after sending out a “mayday” signal, and whether the landing gear was able to operate after the bird strike. The investigation team plans to decide soon whether to secure the connector in South Korea and attempt analysis there, or send the black box itself to the NTSB to check the data.

At least release the communication records with the control tower on the same day. You’re still slow at work. As usual, the bereaved families are obsessed with compensation and damages lol.

It’s also affecting Boeing’s stock price. I need some clarification as to whether this is oink or a common problem with the 737.

“Mayday, bird strike, go around.”
This communication record remains, probably at 8:58. What I’m most curious about is whether there were any reports of landing gear problems.

There are also rumors that the plane landed too far forward on the runway. If it had landed further forward it could have stopped in front of the wall and the damage might have been minimal.

Simply put, we turned too early after the first go-around, and should have waited farther before turning.

In the first place, they forgot to put out the wheels, so it looked like it was in a ‘what?’ state.

I’m sure the flight recorder was destroyed by the South Korean government after it was retrieved, before the US found out.

I’m amazed you were able to break it lol
Airplane black boxes have a sturdy structure that passes rigorous durability tests, including impact, fire, and water depth, and have the following strengths: 
Impact: Withstands 3400g

Fire: Withstands 1100 degrees for over an hour
Water depth: Withstands 6000m

They’ll destroy the data before handing it over to Boeing, and then they’ll cover up the inconvenient parts of the company, wafer ha ha ha. Something like that.

Next, we need to destroy the voice recorder, or else we’ll be found out. The first thing the NTSB and Boeing will do is secure the black boxes, as they are often stolen by certain ethnic groups.

It would be fine to just connect it directly with a connector.

At the very least, it’s better not to take what South Korea says seriously. It won’t lead to anything good anyway.

Boeing
The connector’s come off?
If so, you just need to glue it back together.
We’ll fix it.
Boeing: “We’ve analyzed it. The hydraulics were still there. The gear down operation is not performed. The flap is normal. The bird strike had no effect.”
Korea: “Aigo.”

One theory is that the gear was stored when the plane went around and then forgotten to be taken out.

Normally, during a landing, you communicate with air traffic control to confirm the gear, but
they shouted “Mayday” three times and ignored the procedure…

It has landing lights on the front wheels, so you can see it from a long way away from land.

Was it only the connector part of the flight recorder that was destroyed? I guess time was up.
