Incident Overview
On December 12, 2023, Hokkaido Air System's Flight JL2823, an ATR 42-600 aircraft, experienced mechanical problems shortly after departing from Sapporo Okadama Airport, leading to an emergency landing at Hakodate Airport. The flight was en route to Akita and carried a total of 26 individuals, including 23 passengers and 3 crew members. Fortunately, there were no injuries reported among those on board.
Timeline of Events

- 12:32 PM: The aircraft took off from Sapporo Okadama Airport.
- 12:34 PM: The crew reported instability in the right engine power system.
- 12:35 PM: The crew contacted air traffic control to report the issue.
- 12:45 PM: The destination was changed from Akita to Hakodate.
- 1:33 PM: The aircraft landed at Hakodate Airport.
- 1:37 PM: The plane arrived at the gate.
- 1:58 PM: Passenger disembarkation commenced.
As a result of this incident, three subsequent flights were canceled: Flight JL2824 from Akita to Sapporo/Okadama, Flight JL2865 from Sapporo/Okadama to Kushiro, and Flight JL2864 from Kushiro to Sapporo/Okadama.
Mechanical Issues and Expert Insights
Hokkaido Air System indicated that a potential freezing of one of the propellers may have caused the engine power instability. Experts noted that a malfunction in the de-icing system, which is designed to prevent ice accumulation on the propellers and wings, could be a contributing factor. Despite the mechanical issues, the ATR 42-600 is designed to maintain stable landing capabilities even if one propeller stops functioning.
Official Statements & Responses
Hokkaido Air System confirmed the emergency landing and emphasized that all passengers and crew were unharmed. The airline is likely to conduct a thorough investigation into the mechanical failure to prevent future occurrences.
Criticism & Opposition
While no specific criticisms were reported in the immediate aftermath of the incident, the cancellation of three flights due to the emergency landing may lead to scrutiny regarding the airline's operational protocols and maintenance practices.
Conflicting Reports & Gaps
There were no significant discrepancies in the reports regarding the timeline of events or the nature of the mechanical issues. However, further details on the investigation into the mechanical failure have yet to be disclosed.
What's Next
Hokkaido Air System is expected to release further information following the investigation into the incident, which may include insights into the mechanical failure and any necessary changes to operational procedures.
