The occurrence

The privately operated Cessna U206F floatplane (registration C-FWBQ, serial number U20602785) was flying under visual flight rules from Kuashkuapishiu Lake, Quebec, to Ra-Ma Lake, Quebec, near the Manicouagan Reservoir, Quebec, with the pilot and 2 passengers aboard. After taking off at around 1400 Eastern Daylight Time, the aircraft began a climbing turn to the left while it was at the north end of the lake. A few moments later, the aircraft quickly banked to the right, lost altitude, struck the ground, and immediately caught fire. The fire consumed almost the entire cabin. The pilot was seriously injured, and the 2 passengers were fatally injured. No emergency locator transmitter signal was received.

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.
