The Ministry of Land, Infrastructure and Transportation ordered Asiana Airlines to halt flights from Incheon to Saipan for a week due to a safety violation in April.
The last time the government ordered a carrier to halt flights was in 1997 following the Korean Air crash in Guam.
In April, an Asiana passenger jet continued flying for four hours after a warning signal telling pilots that something was wrong with the engine. The incident happened just four days after the April 16 ferry disaster. Asiana at the time told the ministry that the warning signal had soon disappeared, but investigators said a thorough inspection later revealed it had not.
The flight suspension is expected to cause between W3 billion and W4 billion in losses for Asiana, which planned to operate two to three daily flights to Saipan during the peak summer season.
Although the exact date of the suspension has yet to be finalized, it is apparently expected to happen between July and August.
