The occurrence

On 10 October 2016, a privately operated de Havilland DHC-2 Beaver on amphibious floats departed Vanderhoof, British Columbia for Laidman Lake, British Columbia with 1 pilot and 4 passengers on board. The aircraft was approximately 24 minutes into the flight when it crashed 11 nautical miles east of Laidman Lake. One of the passengers was able to call 911 using their cell phone and a search and rescue operation was initiated. The aircraft was found substantially damaged from collision with terrain.

Transportation Safety Board 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.
