The Transportation Safety Board of Canada (TSB) has released its investigation report regarding a significant incident that occurred in May 2025 at the St-Mathias Water Aerodrome in Quebec. The report details the loss of control and subsequent overturn of a float-equipped De Havilland DHC-2 Mk.I aircraft, which was operated by ETA Aviation & César Camp du Nord inc.

The investigation focused on the circumstances surrounding the accident, which took place during the aircraft's takeoff phase. According to the report, the aircraft experienced a loss of control shortly after becoming airborne, leading to its overturn in the water. This incident raised critical safety concerns, particularly regarding the operational protocols for float-equipped aircraft in similar environments.

In analyzing the factors that contributed to the accident, the TSB emphasized the importance of adhering to established safety measures and conducting thorough pre-flight checks. The report serves as a reminder of the inherent risks associated with water aerodromes and the need for pilots to remain vigilant during takeoff, especially in challenging conditions.

Experts in aviation safety note that incidents like this highlight the necessity for ongoing training and education for pilots operating floatplanes. As the industry continues to evolve, ensuring that operators are equipped with the latest safety information and practices is paramount.

The TSB's findings will likely prompt further discussions within the aviation community regarding operational standards and safety regulations for float-equipped aircraft. The report aims to enhance awareness and prevent similar occurrences in the future, ultimately contributing to safer flying conditions for all.

As the investigation concludes, it underscores the critical role of regulatory bodies in maintaining aviation safety and the ongoing need for vigilance in the operation of specialized aircraft. Stakeholders in the aviation sector are encouraged to review the report and implement any recommended changes to improve safety protocols.
