The occurrence

On 28 September 2014, a de Havilland DHC-6-300 Twin Otter aircraft (registration C-GKSN, serial number 493) operated by Air Labrador Limited, was on a charter flight from Lourdes-de-Blanc-Sablon, Quebec, to La Tabatière, Quebec, with 2 crew members and 17 passengers on board. The aircraft touched down about 750 feet beyond the threshold of Runway 23. During the rollout, the captain determined that the aircraft would not stop before reaching the end of the runway, and initiated a high-speed left turn onto the taxiway. The aircraft skidded to the right, and the right propeller struck a runway identification sign before the aircraft came to a stop. The aircraft sustained substantial damage. There were no injuries, and no fire occurred. The 406-megahertz emergency locator transmitter did not activate. The accident occurred at 1512 Atlantic Standard Time, in daylight.

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.
