As a result of the disaster at Incheon International Airport in South Korea, which claimed the lives of 179 people, the country's authorities decided to implement changes to the cement barriers used at some airports. On December 29, a collision of the Boeing aircraft "Chudju" during landing in Muan occurred, when the plane, arriving from Bangkok, landed without a chassis, skidded on the takeoff-landing strip, and crashed into a cement barrier, catching fire.
All 2216 passengers died, except for two crew members, making this aviation disaster the deadliest in the history of South Korea. After the incident, numerous questions arose about the reasons, including why the end of the runway had a cement structure with built-in equipment for determining the aircraft's position. The Ministry of Planning, Infrastructure and Transportation of the country stated that conducted safety checks revealed the need to introduce changes in the navigation equipment at seven airports, including Muan and the island of Cheju, especially recommending replacing foundation structures with lightweight steel constructions.
Research by the National Institute of Biological Resources of South Korea indicated the presence of debris in the engines of the damaged plane. The scenario of the collision with birds was put forward to explain the disaster, as the control tower of Muan Airport warned the crew of the presence of birds three minutes before landing.
