July 22, 2026 (Farnborough, United Kingdom) — De Havilland Aircraft of Canada Limited (“De Havilland Canada”) today announced that its Twin Otter Re-Life Supplemental Type Certificate (STC) programs are now available to operators worldwide, providing new factory-supported options to extend the service life of DHC-6 Twin Otter aircraft.
Following the acquisition of the Re-Life STCs, De Havilland Canada worked closely with Transport Canada to complete the transfer and validation of the programs and has now integrated them into its aftermarket product portfolio.
The Re-Life STC programs provide approved life-extension solutions for key structural components, helping operators maximize the value of their aircraft, support continued safe and reliable operations, and better plan long-term fleet maintenance.
“De Havilland Canada has invested significant effort to validate these STCs to the standards customers expect from an original equipment manufacturer,” said Rob Mobilio, Chief Commercial Officer at De Havilland Canada. “By making these Re-Life programs available directly through our Aftermarket program, we’re giving operators access to factory-supported life-extension solutions that help protect their investment and keep Twin Otter aircraft flying for years to come.”
The Re-Life STC portfolio now offered by De Havilland Canada includes:
- Wing Box – Extends the wing box service life by replacing key structural components, adding up to 33,000 flight hours or 66,000 flight cycles.
- Flight Controls – Extends the service life of the flaps, ailerons, rudder, and elevators by replacing critical structural components, adding up to 66,000 flight hours or 132,000 flight cycles.
- Engine Nacelles – Replaces the engine nacelles with STC-approved components, extending their service life to 45,000 flight hours or 90,000 flight cycles.
- Fuselage, Horizontal Stabilizer, and Vertical Stabilizer – Extends the service life of the fuselage, horizontal stabilizer, and vertical stabilizer by replacing critical structural components, adding up to 66,000 flight hours or 132,000 flight cycles.
The first Flight Controls Re-Life STC sold by De Havilland Canada is expected to be incorporated later this year.
