TSB says seaplane had faulty repair job months before 2025 crash in Quebec

On Jan. 13, 2026, the TSB released a report linking a faulty repair to the May 2, 2025 crash of a float-equipped De Havilland DHC-2 Mk. I near St-Basile-le-Grand.
A post-crash probe traced the issue to work on the control column, finding maintenance work performed a few months before the crash included a faulty repair where a chain linking the control was not reinstalled correctly.
During takeoff the pilot lost control, the right wing struck the water and detached, and the aircraft overturned underwater in St-Basile-le-Grand.
When crews recovered the seaplane to shore, the pilot was found dead inside the aircraft while the passenger escaped through a window.
The maintenance company has since added an additional independent check for flight-control work, and the TSB safety advice urges thorough pre-flight checks and wearing a personal flotation device.
