The Conair amphibious float-equipped Air Tractor AT-802A Fire Boss, C-FDHV, serial number 802A-0348, was operating as Tanker 692 in support of wildfire management operations 25 nautical miles northwest of Cold Lake, Alberta. Tanker 692 was the last in a formation of 4 AT-802A Fire Boss aircraft followed by 2 CL-215T aircraft being operated by Conair Group Inc. Tanker 692 had completed 2 drops on the fire, from west to east, with a turnout to the north. When exiting its third drop, Tanker 692 encountered severe turbulence and then pitched to a nose-up attitude. The aircraft climbed to approximately 400–500 feet above ground level, where it rolled to the left and entered a nose-down attitude. It struck the ground right-wing low and close to nose-level at 1630 Mountain Daylight Time. The pilot was fatally injured as a result of non-survivable impact forces. There was no post-impact fire.

TSB 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.
