JL585 reserve fuel for landing fell lower than required value

Outline

On July 12, 2023, flight JL585 (from Haneda Airport to Hakodate Airport) diverted to its alternate airport Sapporo New Chitose Airport, due to low visibility at Hakodate Airport. While heading to Sapporo New Chitose Airport, considering the possibility that the amount of reserve fuel remaining at the time of landing would be less than specified amount (fuel able to fly 30 minutes), the flight crew declared priority landing to Air Traffic Control (ATC). When the aircraft landed at Sapporo New Chitose Airport, the remaining fuel value was equal to flying approximately 25 minutes (short of 5 minutes). None of the passengers or crew members were injured. On the next day, this case was classified as a serious incident by Japan Civil Aviation Bureau (JCAB), Ministry of Land, Infrastructure, Transport and Tourism(MLIT).

Investigation into the cause

Japan Transport Safety Board, MLIT is investigating the cause of the incident. JAL Group is providing full cooperation with the investigations.
