    The occurrence

    On 17 November 2025, a Boeing 737-248C operated by Nolinor Aviation was conducting a flight under instrument flight rules from Montréal-Mirabel International Airport, Quebec, to Val-d’Or Regional Airport, Quebec.

    A vibration was felt when the aircraft landed. Directional control was maintained, and normal braking was performed. The vibrations continued until the aircraft came to a complete stop on the runway. The crew informed the airport authority. The airport authority dispatched emergency services, who observed that the right landing gear was damaged.

    No injuries were reported. The passengers disembarked normally by the forward door and were taken to the terminal by bus. The TSB is investigating.

    Class of investigation

    This is a class 4 investigation. These investigations are limited in scope, and while the final reports may contain limited analysis, they do not contain findings or recommendations. Class 4 investigations are generally completed within 220 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.
