South Korea's transport ministry has extended special inspections of all 101 of the Boeing 737-800 jets run by the country's airlines by a week, after the worst aviation disaster on the country's soil,

Accident investigators are trying to find the cause of a Jeju Air fatal crash landing that killed 179 of the 181 on board the flight.

Shares of Boeing fell in early trading on Monday, one day after a Boeing model 737-800 was involved in the Jeju Air plane crash in South Korea that killed scores of passengers. The slide came hours after South Korea's transportation ministry announced it would investigate the crash and conduct a full inspection of all Boeing 737-800 aircraft in use in South Korea.

South Korean officials said Monday they will conduct safety inspections of all Boeing 737-800 aircraft operated by the country's airlines, as they struggle to determine what caused a plane crash that killed 179 people a day earlier.

Joo Jong-wan, the deputy transport minister for civil aviation, acknowledged that safety measures were not sufficient when building the embankment, but said they were done in line

South Korea plans to review the concrete walls positioned just beyond the end of some airport runways after an aircraft attempting an emergency landing smashed into one just over a week ago, killing almost everyone on board.

South Korea’s transport minister is resigning because he feels “heavy responsibility” for the Jeju Air crash that killed 179 people last month. A Jeju Air aircraft carrying 181 passengers and crew crashed at the Muan international airport on 29 December in what was the country’s worst air disaster.

Da Nang and Phu Quoc have seen a sharp decline in South Korean tourist arrivals as a fear of flying has taken hold following the Jeju Air crash.
