    The occurrence

    On 24 November 2023, the privately registered Piper PA-28-180 (Cherokee) aircraft was conducting a visual flight rules (VFR) cross-country flight from Vanderhoof Aerodrome (CAU4), British Columbia (BC), to Invermere Aerodrome (CAA8), BC, with only the pilot on board.

    During the flight, the aircraft reportedly went into a nose-down attitude, approaching the ground at a high speed. The aircraft then reportedly raised its nose abruptly to a level attitude, then rolled to the right as the nose dropped. The aircraft then collided with terrain.

    The Canadian Mission Control Centre did not receive a signal from the aircraft's emergency locator transmitter. Multiple search and rescue helicopter sorties were flown in an attempt to locate the crash site, which was found more than 17 hours after the occurrence.

    The aircraft was destroyed. The pilot was fatally injured.

    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.
