The occurrence

A Cessna 172 aircraft, operated by Airborne Energy Solutions, was conducting a pipeline inspection flight south of Shaunavon, Saskatchewan. The flight consisted of multiple legs to facilitate visual and electronic data collection of pipeline infrastructure, between Swift Current, Saskatchewan, and Estevan, Saskatchewan. At approximately 1015 Central Standard Time, approximately 6 nautical miles southwest of Shaunavon, the aircraft struck a communications tower. A 4-foot section of the aircraft’s right wing was shorn off. The aircraft entered a steep descent and collided with the ground approximately 640 m southeast of the tower. A post-impact fire ensued, which consumed most of the wreckage. The aircraft was destroyed, and the 2 crew members were fatally injured.

Class of investigation

This is a class 4 investigation. These investigations are limited in scope, and while the final reports may contain limited analysis, they do not contain findings or recommendations. Class 4 investigations are generally completed within 220 days. For more information, see the Policy on Occurrence Classification.

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.
