Key Takeaways:

Valdor Aircraft received supplemental type certificate (STC) approval for a comprehensive upgrade of de Havilland DHC-2 Beavers.
The upgrade involves replacing the original radial engine with a modern Pratt & Whitney Canada PT-6A-34 turbine, alongside extensive overhauls including new wings, fuel, oil, and electrical systems.
Dubbed the "BX Turbo Beaver," these modifications aim to significantly increase performance and efficiency while updating the aircraft to meet modern aviation regulations.
The upgrades help extend the service life of the sought-after Beaver aircraft, which often have outlived their original radial engines.

Valdor Aircraft, a Quebec company that provides a range of aircraft services, received supplemental type certificate (STC) approval to install Pratt & Whitney Canada PT-6A-34 engines in de Havilland DHC-2 Beavers.

The recently approved upgrade goes beyond replacing the Beaver’s original Pratt & Whitney R985 radial engine with a modern turbine to increase performance and efficiency. The re-engined Beavers receive new wings, fuel, oil, and electrical systems, engine monitoring, carbon-fiber cowlings, and more. Valdor calls the almost-all-new aircraft the BX Turbo Beaver.
