What happened
During an approach to Pohang Airport, the flight crew encountered adverse weather characterized by heavy rain and significant wind. Following an initial aborted approach, the crew attempted a second landing sequence on runway 10. During this second attempt, a shift in wind conditions resulted in a 20-knot tailwind component.
The aircraft descended at an excessive speed of 158 knots and touched down 1,500 feet beyond the runway threshold. Due to the high velocity and the wet state of the runway surface, the aircraft could not decelerate within the 7,000-foot length of the runway. The aircraft subsequently overran the paved surface, collided with a 3-meter-high embankment, and exited the airfield into a ravine, where the fuselage split into two sections.
All 156 occupants were successfully rescued from the wreckage. Among the passengers, 60 injuries were reported, including two individuals who sustained serious conditions.
Findings
- The presence of a significant tailwind during the final approach contributed to the high touchdown speed.
- The wet runway conditions reduced the available braking effectiveness.
- The aircraft's touchdown point was too far down the runway to allow for a safe stop within the remaining distance.
