The occurrence

On 2 November 2017, a Fairchild SA227-AC Metro III aircraft was conducting a repositioning flight from Gods River, MB (CZGI) to Thompson, MB (CYTH). Approximately 40 nm southeast of CYTH, the crew advised air traffic control of a low oil pressure indication on the left engine and that the engine may need to be shutdown. Upon landing in Thompson with both engines operating, the aircraft veered to the right and exited the runway. The pilot and co-pilot were taken to hospital with minor injuries. The aircraft sustained substantial damage. The TSB is investigating.

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.
