    The occurrence

    On 14 August 2014, an Air Tractor AT-802A on amphibious floats, C-GXNX, was carrying out wild fire fighting operations off Chantslar Lake, British Columbia along with 3 other aircraft of the same model. C-GXNX was second in the formation on a touch-and-go maneuver to pick up water. Upon lift-off, a control issue occurred and the aircraft struck the water, separated from the floats but remained upright and subsequently sank. The pilot was wearing a helmet, a personal floatation device (PFD) and a 4-point safety harness. The pilot received minor injuries, exited the aircraft on his own and inflated the PFD.

    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.
