Two hours of inconvenience at the airport due to the passenger verification system not working... 44 aircraft delayed (comprehensive)

Ministry of Justice "Precise analysis of the cause of failure...Make sure to establish a plan in advance when replacing equipment"

(Seoul, Incheon = Yonhap News) Reporter Choi Won-jeong and Kim Sang-yeon = On the 3rd, a failure occurred in the Ministry of Justice's Passenger Pre-Confirmation System (IPC), causing inconvenience for about two hours, including delays in flights at airports across the country.

According to the Ministry of Justice and Incheon International Airport, at around 6:05 a.m. on this day, the Ministry of Justice's IPC encountered a problem and airline check-in counters at airports across the country linked to it did not work.

IPC is a system that receives passenger information from the airline, checks in real time whether the person scheduled to board is a serious criminal such as an international terrorist, and then informs them of whether they can leave the country and blocks boarding in advance.

The Ministry of Justice ordered the airline to force (manually) issue tickets at around 6:15 a.m., 15 minutes after receiving a report from the Incheon International Airport Immigration Office that the airline was not receiving passenger information.

Passenger information was transmitted to the airline's system at 7:25 a.m., and the Ministry of Justice finally confirmed that the airline's communication response speed had returned to normal at 8:25 a.m., 2 hours and 20 minutes after the failure.

Some congestion occurred while airline employees were checking passenger information, and as a result, 44 of the 201 flights scheduled to depart from airports across the country were delayed. Flight 36's departure was delayed by 30 minutes to 1 hour, and flight 8's departure was delayed by more than an hour.

The Ministry of Justice believes that while Incheon International Airport Authority was replacing old storage devices in the early morning of the same day, passenger information that had not been entered for about two hours was updated at once, causing a system load.

An official from the Ministry of Justice said, "(The flight delay) was at a normal level and all passengers completed departure screening before the scheduled departure time," and added, "We will carefully analyze the cause of the failure and make every effort to establish a plan in advance to ensure that there is no system impact during future work due to equipment replacement."

Previously, at Incheon Airport, on the 30th of last month, some airline check-in systems experienced problems, boarding procedures were suspended for about 13 hours and flights were delayed, causing inconvenience to about 1,200 passengers.
