The occurrence

On 09 November 2015, a privately registered Cessna 182H (registration C-GKNZ, serial number 182-56161) with 1 pilot and 1 passenger on board, departed from the Parry Sound Area Municipal Airport, Ontario, at 1917 Eastern Standard Time under night visual flight rules for a flight to Tillsonburg Airport, Ontario. Once airborne, the aircraft immediately started a right climbing turn for approximately 90° of heading, and then continued its turn for an additional 180° while descending before colliding with the terrain. The aircraft clipped trees in a nose-down attitude with a significant angle of bank to the right before striking the ground on a rocky downward slope. The 2 occupants were fatally injured and a post-impact fire destroyed most of the aircraft. The aircraft was equipped with an emergency locator transmitter, but it was not activated by impact forces. The accident occurred during the hours of darkness.

Class of investigation

This is a class 3 investigation. These investigations analyze a small number of safety issues, and may result in recommendations. Class 3 investigations are generally completed within 450 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.

For more information, see our Investigation process page.

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.
