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.

The South Korean Transport Ministry announced on Wednesday that the concrete feature would be removed from Muan International Airport, according to Reuters. Most other international airports simply mount similar arrays on breakaway posts to allow planes to overrun the pavement across flat ground.

Son Chang-wan, a former president of the state-run Korea Airports Corporation, who spearheaded a controversial facility upgrade at Muan International Airport, was found dead at his home in Gunpo, Gyeonggi Province,

The Ministry of Land, Infrastructure and Transport said it had ordered plans for localizers to be placed underground or replaced with lightweight metal structures within the year

South Korea's transport ministry said on Wednesday that it would remove the concrete embankment installed at Muan International Airport following last month's Jeju Air crash, its deadliest domestic air disaster.

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.
