In an industry defined by constant innovation, few aircraft achieve enduring icon status. Fewer still reach a milestone that speaks not just to engineering success, but to decades of real-world impact. De Havilland Canada has done just that, marking the delivery of its 1000th DHC-6 Twin Otter—an aircraft whose legacy stretches from the remote reaches of the Canadian North to the diverse and demanding terrain of Colombia.

The milestone delivery, alongside the 999th aircraft, will join the fleet of SATENA, Colombia’s state-owned regional airline. It represents both a global production achievement and a deepening partnership rooted in a shared mission: connecting communities that are otherwise difficult to reach.

For more than 60 years, the Twin Otter has defined utility aviation. Originally designed to unlock access to Canada’s most remote regions, the aircraft quickly became synonymous with reliability in extreme conditions. Its ability to operate in harsh climates—from Arctic tundra to tropical environments—combined with its short takeoff and landing (STOL) performance, has made it indispensable for operators worldwide.

That same capability now takes on renewed purpose in Colombia. SATENA, tasked with serving remote and underserved regions, relies on aircraft that can navigate mountains, jungles, coastlines, and isolated rural areas with consistency and efficiency. The addition of the 999th and 1000th Twin Otters strengthens that mission, reinforcing the airline’s role in enabling mobility, economic development, and national integration.

The delivery also marks SATENA’s fourth De Havilland Canada aircraft, underscoring a growing partnership built on performance and operational trust.

“Delivering our 1000th Twin Otter is a proud milestone for De Havilland Canada,” said Brian Chafe, CEO of De Havilland Canada. “Built to connect people in the world’s most challenging environments, the Twin Otter’s success reflects the skill and dedication of our teams and the trust our customers have placed in this aircraft for generations. We’re pleased to see it continue serving communities around the world.”

For SATENA, the significance of the moment extends beyond fleet expansion.

“We are honoured to receive the 1,000th Twin Otter,” said Major General Óscar Zuluaga, President of SATENA. “This aircraft will play a vital role in strengthening connectivity throughout Colombia. As we welcome our fourth De Havilland Canada aircraft, we celebrate not only a milestone in aviation history, but a continued commitment to serving communities that rely on us every day.”

More than a production number, the 1000th Twin Otter stands as a symbol of continuity—of a platform that has remained relevant by doing one thing exceptionally well: going where others cannot. From enabling economic activity in isolated regions to supporting humanitarian and commercial operations, the aircraft has quietly shaped the connectivity of nations.

As it enters its next chapter in Colombia, the Twin Otter carries forward the same purpose it was built for—to open access, create opportunity, and connect people.
