The occurrence

On 19 January 2017, a Victoria Flying Club Cessna 172 was conducting a training flight departing from Victoria Airport, British Columbia, with one student pilot and one instructor on board.

The instructor sustained serious injuries and the student pilot sustained minor injuries.

The son of a Canadian Forces fighter pilot, he was building and flying model aircraft before he was a teenager, and hang gliding by age 15. Mr. Shelongosky is a licensed pilot and a graduate of the British Columbia Institute of Technology's Aircraft Maintenance Engineer (AME) program. After receiving his AME licence, he worked for Central Mountain Air and Harbour Air maintaining a variety of aircraft, including the Beech 1900, Douglas DC-3, de Havilland DHC-2 and DHC-3, and Cessna 180 and 185. He also built, flies and maintains an amateur-built aeroplane.

Transportation Safety Board 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.
