Press Release

Calgary, AB (March 25, 2026) – De Havilland Aircraft of Canada Limited (De Havilland Canada) is proud to announce that the Supplemental Type Certificate (STC) for its CL-415 Avionics Upgrade was officially approved by Transport Canada. This milestone marks a significant advancement in the modernization of the iconic waterbomber platform.

The certification is the result of a highly collaborative effort between De Havilland Canada and its subsidiaries, Mid-Canada Mod Center (MC2) and Avionics Design Services (ADS), in partnership with Universal Avionics. Together, these teams have developed a state-of-the-art avionics solution that enhances operational capability, reliability, and long-term supportability for CL-415 operators worldwide.

“The approval of this STC not only modernizes the CL-415 but also reinforces our commitment to delivering advanced, mission-ready solutions for aerial firefighting operators.” said Jean-Philippe Côté, Vice President, Programs and Business Improvement at De Havilland Canada. “We look forward to deploying these advanced avionics systems across the CL-415 fleet and into the next generation of DHC-515 aircraft.”

This milestone comes during an important period for De Havilland Canada’s waterbomber program, as the company continues to invest in the modernization and long-term sustainability of its fleet. The newly certified avionics suite will also be incorporated into the upcoming DHC-515 aircraft, ensuring fleet commonality and operational efficiency across both platforms.

De Havilland Canada extends its sincere appreciation to the many teams who contributed to this achievement, including engineering, production, flight test, certification, supply chain, programs, maintenance operations, and technical support. Special recognition goes to the MC2 and ADS teams, whose expertise and dedication were instrumental in bringing this program to certification.
