At around 10:49 am on the day of the helicopter crash, the helicopter flies over the village while broadcasting guidance on the forest fire.



[Let's all be careful of forest fires.]



Then, after making a big turn to the right, it suddenly crashed and quickly made three and a half turns.



Even after falling to the ground, the genealogy broadcast continues.



[Hwang Young-man/Village resident: As soon as I went, it caught fire, and the helicopter was completely on fire and burning, and the fire was everywhere...]



The scene of the accident was also caught on the CCTV of a nearby elementary school about 500 meters away.



Part of the fuselage was blown to a house about 100 meters away due to the impact of the explosion, and an expert opinion came out that the tail wing of the helicopter may not have worked properly.



[Yoo Tae-jeong/Professor of Helicopter UAM Pilot Department, Far East University: The tail rotor blade is installed to prevent the fuselage from rotating in the opposite direction to the rotation direction of the main rotor blade.

An aircraft turning sharply to the right is typical of what happens when a tail fin fails.]



The traces of the pilot's efforts until the end to minimize the impact of the accident and the damage to private houses are also visible.



[Yoo Tae-jeong/Professor, Department of Helicopter UAM, Far East University: If a failure occurs (in the rotary wing), auto rotation (automatic gliding flight) is performed.

Looking at the video of the accident, it seems that the autorotation was not executed perfectly.

At the time, the altitude was a little low, and since there are (no open areas) and private houses nearby...]



The Accident Investigation Committee plans to move the crashed helicopter body to the Gimpo Airport investigation room starting tomorrow (the 1st) and begin a detailed investigation to determine the cause of the accident. .



Genetic analysis results for two women out of five helicopter passengers, excluding three flight attendants, are expected to be released tomorrow at the earliest.
