South Korea will remove a concrete structure at the runway of one of its southern airports, the scene of a plane crash that killed all but two of the 181 people on board last month.

Son Chang-wan was in office while works were undertaken at Muan International Airport. Last month, a plane crashed into a concrete barrier there, killing 179 people.

South Korea will tear down concrete walls at several airports, including Muan International Airport, after the Jeju Air plane crash in December.

South Korea will remove concrete embankments from airports after the county’s deadliest domestic air disaster. The wall installed at Muan International Airport will be removed following December’s Jeju Air crash that killed almost 200 people.

South Korea will extend runway safety areas and redesign infrastructure after the crash of a Jeju Air Co flight last month that killed almost everyone on board, sparking criticism that the design of the airport might have exacerbated the accident.

Seven airports will also have their runway safety areas adapted following a review of all South Korea's airports that was carried out after the crash - the deadliest in the country's history. The Jeju Air flight was bringing passengers home from Thailand after Christmas when it made an emergency landing at Muan airport and exploded after slamming into a concrete barrier at the end of the runway.

South Korean authorities said on Wednesday they will change the concrete barriers used for navigation at some airports across the country after the Jeju Air crash that left 179 people dead.
