The occurrence

The Jazz Aviation LP de Havilland DHC-8-102 (registration C-GTAI, serial number 078) was operating as flight JZA7795 on a scheduled flight from Toronto/Lester B. Pearson International Airport, Ontario, to Sault Ste. Marie Airport, Ontario. At 1825 Eastern Standard Time, while on approach to Runway 30 in conditions of twilight and reduced visibility due to blowing snow, the aircraft touched down approximately 450 feet prior to the runway threshold. Following touchdown, the aircraft struck one of the runway approach lights before coming to a stop approximately 1500 feet past the threshold, on the runway surface. There were no injuries to the passengers or to the crew; however, there was significant damage to the aircraft.

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.
