Korean Air KE631 A330 Runway Overrun at Cebu (HL7525)

On October 23, 2022, a Korean Air Airbus A330-322 (HL7525) overran the end of Runway 22 while landing at Mactan–Cebu International Airport in Lapu-Lapu City, Cebu, Philippines. The aircraft struck airport equipment and came to rest in a grassy area beyond the runway after multiple approach attempts in instrument meteorological conditions. Investigators are examining the approach sequence, weather and runway environment, and the aircraft system alerts and performance issues reported during the event.

Accident Summary

What Happened

Public reporting and accident summaries describe the flight as conducting multiple approach attempts to Mactan–Cebu International Airport in heavy rain and low visibility. After the first approach, the crew elected to go around after descending below minima and losing runway visual reference. A second approach was also discontinued, with the flight performing another go-around after an aural “sink rate” warning; the summaries state the landing gear contacted the ground during the go-around initiation.

After the second go-around, the crew held and performed abnormal and checklist actions while managing system alerts. The publicly available summaries describe fault indications involving the landing gear control interface units and anti-skid/brakes, followed later by a hydraulic reservoir low-level message. The flight then continued for another landing attempt.

During the landing that resulted in the excursion, the aircraft was unable to stop on the runway, overran the end of Runway 22, and collided with the localizer antenna and approach lighting equipment before coming to a stop in a grassy area beyond the runway end. The available summaries state there was no post-accident fire and that passengers evacuated using slide rafts from the L2 and R2 doors, after which occupants were transported to the terminal.

Aircraft and Operational Context

The aircraft is publicly identified as an Airbus A330-322, registration HL7525, operating as a scheduled passenger flight (KE631) from Seoul/Incheon to Cebu/Mactan. Passenger counts in public sources vary; some reporting describes 162 passengers onboard, while other summaries list 165 passengers, with 11 crew. Injury reporting also varies across sources, with one summary reporting minor injuries among crew and passengers and other reporting emphasizing survivability.

Instrument meteorological conditions were reported at the time of the accident, with heavy rain and changing winds described as affecting runway selection and approach continuity. In such environments, approach stability, runway visual reference acquisition, and strict adherence to go-around criteria can become central to how investigators frame the event. The specific runway condition measurements and braking action assessments were not publicly reported in the materials provided.

Accident Investigation

Aviation investigations typically proceed from early operational reconstruction to detailed systems analysis and final reporting, as explained in our overview of the aircraft accident investigation process. For this event, public summaries reference system alert messages and the sequence of approach attempts, which investigators commonly corroborate using flight data, maintenance records, and air traffic control communications.

Investigators generally examine how weather and runway environment interacted with aircraft energy management and stopping performance, and they assess the timing and operational impact of any faults or warning messages that appeared during the approach sequence. Where airport equipment is struck during an overrun, investigative work also typically documents the aircraft path beyond the runway end and the condition and location of the impacted infrastructure.

Operational and Regulatory Issues

Multiple approach attempts in convective or heavy-rain conditions can increase flight deck workload and compress decision timelines, particularly if abnormal indications emerge between attempts. Investigators often evaluate stabilized approach criteria, the decision-making leading to go-arounds, and the adequacy of operational guidance for continuing or discontinuing approaches in rapidly changing conditions. The publicly available summaries emphasize heavy rain, loss of runway visibility, and system fault messages prior to the runway excursion.

Runway excursion analysis frequently includes stopping performance considerations, including the availability and effectiveness of braking, anti-skid, spoilers, and thrust reversers, as well as runway surface condition and potential contamination. Where a fault affects a deceleration system, investigators typically review whether cockpit indications were inhibited or delayed, how quickly they became actionable, and what checklist actions were completed before the subsequent approach and landing attempt.

Aviation Accident Litigation

Separate from the safety investigation, civil claims arising from runway excursions often focus on operational decision-making, injury causation, and the evidentiary record surrounding aircraft systems, maintenance history, and warnings, as outlined in our overview of aviation accident litigation. For international events, applicable law and jurisdictional questions can shape how claims are evaluated and where they may be brought. Any legal assessment should remain grounded in verified investigative findings rather than early summaries.

When litigation involves aircraft system alerts, braking effectiveness, or runway/environmental factors, case development can require detailed technical work, including document discovery and expert analysis consistent with issues seen across the firm’s aviation matters experience. Depending on the facts established, civil issues can involve airline operational procedures, training and oversight, airport condition information, and manufacturer component/system performance questions.

Where matters resolve, outcomes generally turn on technical causation proof and individualized damages evidence, as reflected in the firm’s summaries of aviation verdicts and settlements. Broader context on how event severity and injury mix can influence civil outcomes is discussed in our overview of aviation verdict trends.
