The Ministry of Land, Infrastructure and Transport announced on the 30th that the landing point of the Jeju Air aircraft, which was involved in an accident at Muan International Airport in South Jeolla Province on the morning of the 29th, was confirmed to have passed the usual landing point.
Yu Kyung-soo, Director General of aviation safety policies at the Ministry of Land, Infrastructure and Transport, stated during a briefing on the Jeju Air Muan Airport accident held at 10 a.m. on the 30th, that the landing point of the accident aircraft is estimated to be on runway direction 19 (reverse direction, north to south) at the one-third point. In meters, the landing occurred past the 1,200-meter point on the 2,800-meter-long runway. The aircraft ran 1,600 meters and then veered off.
According to the summary provided by the Ministry of Land, Infrastructure and Transport, the accident aircraft ran 1,600 meters along the runway in a belly landing state before veering off the runway. It first collided with a localizer, which appeared like a mound installed 199 meters away from the southern end of the runway, and then had a secondary collision with an outer wall. The outer wall is located 124 meters from the localizer and 323 meters from the southern end of the runway.
The point at which the accident aircraft landed on the runway exceeded the usual aircraft landing point, known as the touchdown zone. The usual touchdown zone for aircraft is formed within 300 to 900 meters from the end of the runway. Director General Yu stated, "It is true that the accident aircraft landed beyond the marked touchdown zone on the runway."
Based on calculations from the Ministry of Land, Infrastructure and Transport's explanation, the accident aircraft ran for 1,800 meters after initial ground contact before colliding first with a localizer. The video suggests the aircraft ran along the runway for approximately 20 seconds.
It is estimated that the aircraft was traveling at an average speed of 90 meters per second (equivalent to 324 kilometers per hour). A Ministry of Land, Infrastructure and Transport official noted, "There may be second-level errors. The aircraft's speed at the time of the accident needs to be determined through the retrieved flight data recorder (FDR)."
