Collision with terrain
Updated on 27 December 2017
The following update contains facts that the TSB has been able to validate at this time. It contains no conclusions about the factors that contributed to the occurrence. The final investigation report will include an analysis of all relevant factors and provide the Board's findings.
On 13 December 2017, a ATR42-320 aircraft operated by West Wind Aviation as flight WEW282 departed Fond-du-Lac Airport, Saskatchewan (ZFD) for Stony Rapids, Saskatchewan (YSF) with 22 passengers and 3 crew on board. At 1812, shortly after takeoff, the aircraft collided with trees and terrain less than a mile west of the end of Runway 28. The aircraft was destroyed. Six passengers and one crew member sustained serious injuries. Eighteen other aircraft occupants were also injured. One of the seriously injured passengers subsequently died. The TSB is investigating.
Progress to date
An investigation team including air investigators and technical experts from the TSB Engineering Laboratory in Ottawa was deployed to the accident site. The team is wrapping up the field phase of the investigation, and will be leaving once the aircraft has been moved to a secure location. Selected components will be shipped to the TSB Lab for further examination and testing. So far the team has:
What we know based on the initial examination
Safety action taken
Working with others

We would also like to recognize the contributions of the Royal Canadian Mounted Police (RCMP) and of the local Canadian Rangers who protected the site.
Among other activities in the coming days and weeks, the team will:
Communication of safety deficiencies
Investigations are complex and we take the time needed to complete a thorough investigation. However, should the investigation team uncover safety deficiencies that present an immediate risk, the Board will communicate them without delay.
Further, it is important not to speculate, or draw conclusions as to causes at this time. There are often many factors that can contribute to an accident.

Transportation Safety Board investigation process
There are 3 phases to a TSB investigation:
- Field phase: a team of investigators examines the occurrence site and wreckage, interviews witnesses and collects pertinent information.
- 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.
- 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.
