HL8088 737-800 Runway Overrun at Muan
Contents
On 29 December 2024, a Boeing 737-800, HL8088, operated by Jeju Air was approachiong Muan, South Korea, runway 01,
The aircraft went around due to a bird strike. Several popping sounds and flames from an engine were seen by observers on the ground. The crew declared a mayday and requested an approach on the opposite runway (19).
Video footage appears to show the aircraft touching down apporximately 1200m into the 2800m runway with gear, flaps and slats retracted just 3 minutes after the initial go around. The aircraft overran the runway and hit a concrete wall 300m past the runway end and was destroyed in the impact.
175 passengers and 4 crew died. Only 2 cabin crew members survived, they were seated at the rear of the aircraft.

Muan airport is surrounded on 3 sides by seashore and wetland which according to the EAIP "provide good nesting habitat for both resident birds such as Black-billed Magpie, Ring-necked Pheasant, Rufous Turtle Dove, Tree Sparrow, Mew Gull and migratory birds such as Mallard, Gray Heron, Egret, House Swallow.". "Muan International Airport strives to prevent bird strikes by implementing both non-lethal techniques, gas cannons and playback of distress calls, and lethal techniques, live ammunition shooting, during airport operating hours."
The following questions will be key to the investigation:
- What engines and systems damage was sustained by the birdstrike
- Why was the landing gear not down and locked
- Why where the flaps and slats not deployed
- Why did the aircraft land so far down the runway
- Why was there a concrete structure in the runway overrun
- Why was power to the FDR and CVR lost 4 minutes prior to impact
For those unfamiliar with Boeing 737 systems:
The landing gear is normally operated by hydraulic system A. There is a gravity extension mechanism as a backup in case of the loss of hydraulics.
The flaps and slats are normally operated by hydraulic system B. There is an electical extension mechanism as a backup in case of the loss of hydraulics.
