Circumstances:
On approach to Pohang Airport, the crew encountered poor weather conditions with rain falls and strong winds. The captain decided to initiate a go-around procedure and started a second approach few minutes later. On approach to runway 10, the wind component changed and the crew continued the descent with a 20 knots tailwind. At an excessive speed of 158 knots, the aircraft landed 1,500 feet past the runway threshold. On a wet runway surface, the aircraft was unable to stop within the remaining distance (runway 10 is 7,000 feet long), overran, struck a 3 metres high embankment and came to rest in a ravine, broken in two. All 156 occupants were rescued, among them 60 passengers were injured, two seriously.
Probable cause:
The following findings were identified:
- Poor crew action during an approach in poor weather conditions,
- Excessive tailwind component,
- Misuse of brake and thrust reverser systems during the landing roll, about 27 seconds after touchdown only,
- The crew failed to initiate a go-around procedure as the landing was obviously missed,
- Poor ground assistance.

Circumstances:
Originally, the flight was a direct one from Tokyo-Narita to Seoul but due to poor weather conditions at destination, the crew diverted to Jeju. The aircraft departed Jeju Airport at 2107LT on the final leg to Seoul-Gimpo Airport. At destination, weather conditions were still poor with heavy rain falls and wind from 220 gusting to 22 knots. After touchdown on runway 14R, the crew started the braking procedure but the aircraft deviated to the right and veered off runway. While contacting soft ground, the aircraft lost its undercarriage and came to rest. All 395 occupants evacuated, among them 20 were slightly injured. The aircraft was damaged beyond repair.
Probable cause:
It was determined that the loss of control after touchdown was the consequence of the captain's misuse of the thrust reverser during the landing roll and his confusion over crosswind conditions. Investigations revealed that after touchdown, the n°1 engine thrust reverser did not deploy because the n°1 engine power lever's position did not allow the reverser to be deployed. The following contributing factors were identified:
- Poor weather conditions,
- Cross wind component,
- Wet runway surface,
- Poor braking action.
