The occurrence
On 02 August 2022, the Air Tractor, Inc. AT-802A aircraft (registration C-FFQS, serial number 802A-0629), equipped with amphibious floats and operated by Conair Group Inc. as Fireguard 673, was conducting aerial firefighting operations from Cranbrook/Canadian Rockies International Airport (CYXC), British Columbia, with 1 crew member on board. Fireguard 673 was the 4th aircraft working in a group of 4, with 1 additional aircraft acting as a bird dog. After conducting the 8th water drop on the Connell Ridge wildfire, the pilot of Fireguard 673 applied power for the climb-out, but the engine power rolled back to idle. When he then selected the emergency power lever, no more power was produced. The pilot selected a reforested area and completed a forced landing. The pilot sustained minor injuries and was taken by helicopter to receive medical aid. There was no post-impact fire. The aircraft was substantially damaged.

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.

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.
