Synopsis
On October 23, 2022, at approximately 2310 local time (1510 UTC), an Airbus A330-322 aircraft with registration HL7525, operated by Korean Air Lines Co., Ltd., experienced a runway overrun during the landing roll on Runway 22 at Mactan-Cebu International Airport (RPVM), Lapu-Lapu City, Cebu, Philippines. The flight was a scheduled commercial operation from Incheon International Airport, Korea. Instrument meteorological conditions prevailed at the time of the accident.
Injuries
One flight crew member, four cabin crew members, and fifteen passengers sustained minor injuries.
Damage to Aircraft
The aircraft sustained damage during the runway overrun, including multiple faults to the right-hand main landing gear (MLG) and loss of braking capability.
History of Flight
The aircraft conducted several approaches to Runway 22. During the second approach, the aircraft made ground contact before the runway threshold. The right-hand main landing gear struck a 15-centimeter step of the cemented edge of Runway 22, resulting in damage to the lower articulating link, bogie pitch trimmer, brake manifold, hoses, harnesses, and other components. Subsequently, during the fourth approach and landing, the aircraft experienced a loss of alternate braking and most deceleration means, leading to a runway overrun.
Cause Factors
The Aircraft Accident Investigation and Inquiry Board determined that the cause factors of this accident were attributed to:
- The increase of vertical speed indicator (VSI) attributed to the forward pitch control from the captain that resulted in ground contact before the runway.
- The increase in vertical wind factor during the aircraft's descent on the second approach.
- The right-hand main landing gear hitting a 15-centimeter step of the cemented edge of Runway 22, resulting in multiple damage and faults to the said landing gear, and consequently the loss of most of the deceleration means, specifically aircraft braking failure resulting in runway overrun.
