Jeju Air flight 120, a Boeing 737-800 airplane, suffered a runway excursion incident at Seoul-Gimpo Airport, South Korea.
The flight took off from Jeju International Airport about 21:09, and landed at Gimpo at 22:18. However it failed to decelerate and veered off the runway as it attempted to vacate runway 14R via taxiway B1 at the end of the runway.
There was no damage to the aircraft and there were no personal injuries.

The Aviation and Railway Acident Investigation Board (ARAIB) determines that the causes of this serious incident were
1. Since the flight crew failed to carefully consider the runway condition before landing, they failed to neither predict and select the braking action of the runway under adverse conditions during landing nor share information on landing distance and deceleration plan between the Pilot Flying (PF) and the Pilot Monitoring (PM);
2. The PF not only disengaged the deceleration system altogether before the aircraft decelerated enough to vacate the runway during landing roll, but also failed to respond to the slippery condition in the last 1/3 section of the runway since he mistakenly believed that the remaining distance to the end of the runway was enough.

Contributing to this serious incident were (1) the PF's failure to conduct the landing briefing; and (2) non-provision of the runway surface information after snow removal operations on runway 14R for the flight crew.
