Expert opinion so far, excluding the area of speculation, the crash of a plane

Expert opinion so far, excluding the area of speculation, the crash of a plane at Muan International Airport in Jeollanam-do

Below is a brief report on the situation so far, cross-checked with the flight manager. The most important is the last sentence.

"Until then, it's all about speculation"

■ When did the problem occur
The aircraft went through MRO (aircraft inspection) before takeoff. When departing from Thailand, there were no wheels or abnormalities. It seems that a problem occurred before landing in Muan.

■ the cause of an accident
In some cases, the engine is turned off by a bird-like, and the aircraft is designed to get thrust with just one engine in case of such a situation.
Although it is rare for both engines to be turned off at the same time, it is estimated that both engines were lost due to bird strikes in the Jeju Air accident.
A representative example of an accident caused by a bird-like) Miracle on the Hudson River

■ Things to Watch Out for in the Press
Overlapping the landing gear problem could be a coincidence (cautiously) (of course, the engine failed due to the bird strike, which may have disabled the landing gear by hydraulic pressure guns)
So far, the contents of the hydraulic system are only the principled theory of the model (B737-800).
This questioning is also an area of speculation.

■ Check it out
After all, you have to see CVR and FDR. CVR and FDR are located at the tail of an aircraft.
In particular, black boxes are made durable against impact and fire due to the nature of aircraft accidents. An orange color that is easy to spot.
It takes a long time to solve both data. Aircraft accident investigations usually take six months to three years.
Also, in a normal aircraft accident, the survival probability of the wing or rear part is high. This time again, the two data located in the tail must have been found, as it appears that survivors came from the rear.
However, if either of these is not found, there may be doubts.

■ Other than that
First of all, the only video that has been released is the informant's video. The communication details with the control tower and the above two data must be provided for proper analysis.
Until then, all areas of speculation.

■ Addition
-Point out that the problem is that the bird alarm went off and it landed
Even though there is a bird warning, it is not prohibited to take off and land. It is purely the judgment of the captain. It is not common for a captain to say that a bird cannot take off and land. It is not easy for a company to make such a decision.

-Is the B737-800 model a problem?
The B737MAX is a talkative model. Recently there was an issue, and due to the stigma, the name was changed to the 737-8. Some people misunderstand it as the same model they bought and claim it's a problem.

-Is it because it's LCC?
LCC does not apply differently to the maintenance regulations. However, there is a culture that is fast, such as FSC and LCC.

-Muan runway length issue?
Daegu and Cheongju are shorter on the runway than Muan.
The 2.8 km Muan runway has no problem for the model (B737-800) to take off and land.
The landing distance is salty because the weather is cold now.
