Incident Overview
An aircraft conducting a flight from Sapporo to Nakashibetsu Airport experienced a crash landing short of the runway during its final approach. The incident occurred in marginal weather conditions, with the crew initiating a descent to the airport before encountering difficulties.
Sequence of Events
After an uneventful flight from Sapporo, the crew began the descent to Nakashibetsu Airport. While on final approach, the aircraft performed a last turn to the left at an angle of 30°. During this turn, the aircraft struck the ground and crash landed in a snow-covered field. The snow depth was approximately 40 centimeters. Following impact, the aircraft slid for several dozen meters before coming to rest 100 meters short of the threshold of runway 23. The force of the landing caused the airframe to break into two sections.
Injuries and Damage
According to the official report, 31 of the occupants sustained injuries, while 22 other occupants escaped without injury. The aircraft was substantially damaged, breaking in two upon coming to rest.
Probable Cause
The official investigation determined the probable cause to be the pilot-in-command's misjudgment of altitude and distance while completing the approach in low ceiling conditions. Improper control of the engine power was cited as a contributing factor.
