Aviation Investigation A15O0188

Collision with terrain

The occurrence

On 9 November 2015, a Cessna 182H departed the Parry Sound municipal airport for a night flight to Tillsonburg, Ontario. Just after takeoff from Runway 35, the aircraft turned left towards Tillsonburg. The aircraft was reported crashing in the woods near highway 400, west of the airport. The aircraft had clipped trees in a nose-down attitude with a significant angle of bank, impacting the ground on a rocky downward slope. The two occupants were fatally injured; a post-impact fire destroyed most of the aircraft.

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.
