The occurrence
On 24 September 2025, a privately registered, amateur-built Bushmaster Super 22 aircraft departed Lillooet Aerodrome, British Columbia, on a recreational flight to Chilliwack Airport, British Columbia, with only the pilot on board.
Shortly after takeoff, the aircraft levelled at about 300 feet above ground level and turned back towards the aerodrome. En route, the aircraft collided with trees and then terrain, coming to rest upside down. The pilot was fatally injured. The aircraft was substantially damaged; 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.
