기본 사실

• 원인

  It is highly probable that this serious incident occurred when the Aircraft landed on RWY 10 in Niigata Airport, the Captain did not let the Aircraft reduce enough lower speed to approach the runway threshold lights that the Captain understood as the stop bar lights for the intersecting RWY 04/22, which the Captain was holding a doubt, and when the Captain realized there was no runway beyond the red lights, the Aircraft could not stop within the runway anymore, resulting in overrunning.

• 기여요인

  Both the Captain and the F/O presumed that the ATC instruction “cross runway 04/22” from the Niigata Tower was “the clearance to cross the intersecting runway during landing roll” rather than “the taxi clearance including crossing the intersecting runway after vacating the runway,” unable to understand the intention of the instruction, and both of them believed the Aircraft was short of the intersecting runway.

• 기여요인

  The Captain was going to roll to the end of the runway; therefore, he disarmed the autobrakes as fast as about 70 kt. After that the Captain could not take appropriate control of reducing speed with manual braking, even though he should have reduced speed in a careful manner.

• 기여요인

  The Captain and the F/O were not familiar with Niigata Airport which had a intersecting runway, and they had difficulty to identify the intersecting position with RWY 04/22 because ground objects and others which pilots could observe during night landing were limited. In such circumstances, it was difficult for them to judge the speed of the Aircraft in the low speed area in which they did not count on the airspeed indicator.
