What happened
On July 9, 2026, an Air Canada Boeing B737-800 (Max) operating under instrument flight rules arrived at Montréal/Pierre Elliott Trudeau International Airport in Quebec. The aircraft was inbound from Los Angeles International Airport in the United States, carrying 155 passengers and six crew members.
Upon landing on Runway 06L, which had a wet surface, the pilot initiated deceleration procedures. During this phase, the pilot executed a right turn to utilize high-speed exit taxiway B3. The aircraft subsequently departed the paved surface, entering the grass area. It came to rest approximately 100 feet south of taxiway B and roughly 800 feet from the runway edge.
No injuries were reported among those on board. Post-incident inspection revealed that damage was confined to the left engine, which had ingested foreign objects during the excursion.
The investigation
Following the event, Transportation Safety Board of Canada (TSB) investigators deployed to the scene to collect initial information and assess the incident. The laboratory team subsequently extracted data from both the flight data recorder and the cockpit voice recorder to reconstruct the sequence of events.
In the days following the occurrence, investigators returned to the site to conduct precise measurements of the aircraft's trajectory. They also documented marks left on the runway surface and measured the texture of the pavement. These physical assessments were performed to calculate wheel grip coefficients, providing critical data regarding the friction conditions present during the landing roll.
