Circumstances:
The crew was completing a local training at Jeju-Jungseok Airport. On approach via 'White 2' airway, the captain cancelled his IFR flight plan and continued under VFR when, at an altitude of 2,300 feet, the aircraft struck east side of Mt Hallasan (1,950 meters high). The wreckage was found about 8 km west of the airport at an altitude of about 700 meters. All three crew members were injured and the aircraft was destroyed.
Probable cause:
For unknown reasons, the crew initiated the approach to Jeju-Jungseok Airport from the west while the standard procedure required an approach from the north. At the time of the accident, the visibility was poor due to low clouds and Mt Hallasan was shrouded in clouds.

Circumstances:
During the takeoff roll at Seoul-Gimpo Airport, the left engine lost power and severe vibrations were encountered. The captain decided to abandon the takeoff and initiated an emergency braking procedure. Unable to stop within the remaining distance, the aircraft overran, lost its undercarriage, cartwheeled and came to rest, bursting into flames. All 48 occupants were evacuated, among them 21 were injured. The aircraft was totally destroyed.
Probable cause:
It was determined that the loss of power on the left engine was the consequence of ice that detached from the left upper wing and went into the engine. This caused the high pressure compressor to stall, followed by vibrations and a loss of directional control.
The following contributing factors were reported:
- Poor flight preparation on part of the flying crew,
- The aircraft has not been properly deiced prior to takeoff.

Circumstances:
Following an uneventful flight from Los Angeles via Anchorage, the crew started the approach to Seoul-Gimpo Airport in the early morning, just after sunset. On final to runway 14, with a limited visibility of 1,000 meters due to patches of fog, the crew failed to realize his altitude was insufficient when the airplane landed 90 meters short of runway threshold. Then the aircraft struck a concrete wall, causing all main gears to be torn off or to pushed back in their respective wheel well, except the nose gear which remained intact. The airplane slid on its belly for about 1,200 metres before coming to rest in flames on the left side of the runway. 14 occupants escaped uninjured while 198 others were injured. Unfortunately, eight passengers and six crew members, among them both pilots, were killed. The aircraft was destroyed by a fire that probably ignited in a cargo compartment.
Probable cause:
Wrong approach configuration on part of the flying crew who continued the approach below the glide without any visual contact with the ground until the airplane struck the ground short of runway.
