The occurrence

On , at approximately 0852 Eastern Daylight Time, the float-equipped de Havilland DHC-2 Mk. I Beaver aircraft (registration C-FBBG, serial number 358), operated by Hawk Air, departed from the Hawk Junction Water Aerodrome, on Hawk Lake, Ontario. The aircraft, with the pilot and 1 passenger on board, was on a daytime visual flight rules charter flight. The aircraft was going to drop off supplies at an outpost camp on Oba Lake, Ontario, approximately 35 nautical miles north-northeast of the Hawk Junction Water Aerodrome.

The aircraft departed heading northeast. Shortly after takeoff, during the initial climb out, just past the northeast end of Hawk Lake, the aircraft crashed in a steep nose-down attitude, severing a power line immediately before impact, and coming to rest next to a hydro substation.

The pilot and the passenger received fatal injuries. The aircraft was destroyed as a result of the impact, but there was no post-impact fire. The emergency locator transmitter activated on impact, and the signal was received by the Joint Rescue Coordination Centre in Trenton, Ontario.

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.
