Collision with runway light on landing

Baie-Comeau Airport
Baie-Comeau, Quebec

The occurrence

On the evening of , a Bombardier Dash-8-300 aircraft, operated by Jazz Aviation LP as JZA8964, was conducting a scheduled instrument flight rules flight from Mont-Joli to Baie-Comeau, both located in the province of Quebec. There were 3 crew members and 18 passengers on board. On that day, the width of Runway 10 at the Baie-Comeau Airport had been reduced by half (75 feet) due to construction work. Upon landing, the aircraft was aligned with the center of the runway, and the right landing gear touched down on the closed area. As the aircraft moved towards the open area of the runway, the inboard wheel of the right main landing gear struck a temporary runway light and the tire punctured. No injuries or damage was reported. There were no closed runway signs on the south end of the runway. The TSB is investigating.

Class of investigation

This is a class 5 investigation. Class 5 investigations are limited to collecting data, which are then stored in the modal database. If TSB investigators deployed to the occurrence site, a short description of the occurrence is posted to the TSB website once the investigation has been completed. These investigations are generally completed within 90 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.

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.
