Circumstances:

On approach to Sapporo-Okadama, the aircraft was too high on the glide and approached at an excessive speed. It landed too far down a snow covered runway and was unable to stop within the remaining distance. It overran, collided with snow bank and came to rest. All 41 occupants escaped uninjured while the aircraft was damaged beyond repair.

Probable cause:

Wrong approach configuration on part of the crew who completed the approach at an excessive speed and above the glide, causing the aircraft to land too far down the runway. The following findings were identified:
- The aircraft speed was 23 knots higher than the reference speed above threshold,
- Excessive speed upon touchdown,
- The braking action was reduced because the runway surface was contaminated with snow,
- The aircraft was unable to stop within the remaining distance,
- The crew failed to initiate a go-around procedure while the landing was obviously missed,
- Marginal weather conditions,
- Poor crew coordination,
- Poor airspeed monitoring on part of the flying crew.

Circumstances:

Following an uneventful flight from Sapporo, the crew started the descent to Nakashibetsu Airport in marginal weather conditions. On final, while completing a last turn to the left at an angle of 30°, the aircraft struck the ground and crash landed in a snow covered field (40 cm deep snow). It slid for few dozen meters and came to rest 100 meters short of runway 23 threshold, broken in two. 31 occupants were injured and 22 other occupants escaped uninjured.

Probable cause:

The pilot-in-command misjudged altitude and distance while completing the approach in low ceiling. Improper control of the engine power was a contributing factor.

Circumstances:

While descending to Hakodate Airport, the crew encountered poor weather conditions. At an altitude of 6,000 feet, the airplane struck the slope of Mt Yokotsu located 18 km north of Hakodate Airport. The aircraft disintegrated on impact and all 68 occupants have been killed.

Probable cause:

The flight crew mistook a point approximately 5 nautical miles north of the Hakodate NDB as being just over the Hakodate NDB, a navigation aid, and initiated their descent from an estimated altitude of 6,000 feet in an attempt to cross the high station at 2,500 feet by making a single circle. The outbound flight leg was extended westward and because of a strong southwesterly wind, the aircraft drifted further to the north than the crew expected, striking the mountain. It is so considered that the accident was the consequence of a controlled flight into terrain.
