    The occurrence

    On 14 January 2025, a De Havilland DHC-8-314 aircraft operated, by Air Inuit with 6 passengers and 3 crew members on board, was conducting a flight from La Grande Rivière Airport, Quebec, to Montréal/Pierre-Elliott-Trudeau International Airport, Quebec.

    Approximately 2 hours into the flight, when the aircraft was at its cruising altitude, the left engine shut down because of a fuel issue. The crew then declared an emergency with the air traffic control unit and diverted to Chibougamau-Chapais Airport, Quebec, where the aircraft landed uneventfully. The TSB is investigating.

    Class of investigation

    This is a class 3 investigation. These investigations analyze a small number of safety issues, and may result in recommendations. Class 3 investigations are generally completed within 450 days. For more information, see the Policy on Occurrence Classification.

    TSB investigation process

    There are 3 phases to a TSB investigation

    1. Field phase: a team of investigators examines the occurrence site and wreckage, interviews witnesses and collects pertinent information.
    2. Examination and analysis phase: the TSB reviews pertinent records, tests components of the wreckage in the lab, determines the sequence of events and identifies safety deficiencies. When safety deficiencies are suspected or confirmed, the TSB advises the appropriate authority without waiting until publication of the final report.
    3. Report phase: a confidential draft report is approved by the Board and sent to persons and corporations who are directly concerned by the report. They then have the opportunity to dispute or correct information they believe to be incorrect. The Board considers all representations before approving the final report, which is subsequently released to the public.

    The TSB is an independent agency that investigates air, marine, pipeline, and rail transportation occurrences. Its sole aim is the advancement of transportation safety. It is not the function of the Board to assign fault or determine civil or criminal liability.
